THE BLOOD HUNTERS

The Boner’s Botanicals DIY Mosquito Arsenal

How to “Jam” Their Sensors — And Fight Back

Mosquitoes have been hunting for blood for millions of years, and they have become remarkably sophisticated at finding us. They don't need binoculars, GPS, or a search party. Instead, they use a combination of carbon dioxide, body odor, body heat, moisture, and other chemical signals to locate a potential meal. Once they get within range, they can use those signals to zero in on exposed skin.

But mosquitoes aren't all the same. Different species have different habitats, feeding preferences, geographic ranges, and even different times of day when they are most active. Understanding which mosquitoes you're dealing with is an important part of understanding how to protect yourself.

That brings us to the purpose of this article and our Boner's Botanicals DIY Mosquito Arsenal. We've put together five botanical-based preparations using ingredients that have been studied for mosquito-repelling activity, skin care, or formulation properties. Some have interesting scientific evidence behind them, while others are best viewed as traditional or experimental approaches.

Before we break out the arsenal, however, let's take a closer look at three mosquitoes that are especially important in the United States.

KNOW YOUR ENEMY

For this project, we're focusing on Aedes aegypti, Aedes albopictus, and Culex quinquefasciatus. These three mosquitoes have different behaviors and geographic distributions, which makes them a good illustration of just how diverse the mosquito battlefield can be.

Aedes aegypti — The Yellow-Fever Mosquito

Aedes aegypti is a small, dark mosquito that has become exceptionally well adapted to living around people. In the United States, it is primarily associated with the South, Southeast, Gulf Coast, Florida, Texas, and portions of the Southwest. Its broader global distribution includes tropical and subtropical regions around the world.

Unlike mosquitoes that spend much of their time in wetlands or natural habitats, Aedes aegypti can thrive in and around human residences. It can reproduce in relatively small amounts of standing water found in flowerpots, buckets, discarded containers, tires, pet dishes, and other objects capable of collecting rainwater.

Aedes aegypti is also an important human-biting mosquito and is primarily active during the daytime, with increased activity around dawn and dusk. It can transmit several viruses of public-health importance, including dengue, Zika, chikungunya, and yellow fever.

This is one reason mosquito control around the home matters. You don't necessarily need a pond, swamp, or marsh nearby to have a mosquito problem. Sometimes, all it takes is a forgotten container holding a little water in the backyard.

Aedes albopictus — The Asian Tiger Mosquito

Aedes albopictus, commonly known as the Asian tiger mosquito, is one of the easiest mosquitoes to recognize because of its distinctive black-and-white markings and banded legs. It has become widespread throughout much of the United States.

Its potential U.S. range includes much of the Southeast and Gulf Coast, extending northward into portions of the Midwest and Mid-Atlantic and into areas of the West and Southwest. One characteristic that has helped this species establish itself across such a broad area is its ability to tolerate cooler temperatures than Aedes aegypti.

Like Aedes aegypti, the Asian tiger mosquito is comfortable living around people and can use small containers of standing water as breeding sites. It is also primarily a daytime biter, meaning you don't necessarily have to wait until sunset to encounter it.

Aedes albopictus feeds on both people and animals and is capable of transmitting viruses including dengue, Zika, and chikungunya. Its feeding behavior and ecology differ from Aedes aegypti, however, which is another reminder that the term "mosquito" covers a remarkably diverse group of insects.

If you've ever been working in the yard during the day and suddenly found yourself being attacked by a small black-and-white mosquito, there is a good chance you've met the Asian tiger.

Culex quinquefasciatus — The Southern House Mosquito

Culex quinquefasciatus, commonly called the southern house mosquito, follows a somewhat different playbook. In the United States, it is primarily associated with the southern states, extending from the Southeast and Gulf Coast across the southern Plains and into the Southwest and California.

Unlike the two Aedes species discussed above, Culex quinquefasciatus is primarily a nighttime mosquito. It commonly becomes active during the evening and continues feeding after dark.

Culex mosquitoes also have a particularly important relationship with birds. Female mosquitoes feed on both birds and mammals, and this feeding behavior is significant because birds can serve as important hosts in the transmission cycle of West Nile virus. Culex mosquitoes are among the important vectors involved in the transmission of West Nile virus and other mosquito-borne viruses.

So while Aedes mosquitoes may be looking for you while you're working outside during the day, Culex can be waiting for you after the sun goes down.

THREE MOSQUITOES, THREE DIFFERENT PLAYBOOKS

Aedes aegypti, Aedes albopictus, and Culex quinquefasciatus demonstrate just how different mosquito species can be. Their geographic ranges overlap in many places, but their preferred habitats, feeding behavior, and active periods are not identical.

Aedes aegypti and Aedes albopictus are primarily daytime biters and are strongly associated with residential environments and small containers of standing water. Culex quinquefasciatus is primarily nocturnal and has an important ecological connection with birds.

The common denominator is that all three need to locate a host before they can bite.

And that brings us to the central question behind Mosquito Warfare: if mosquitoes use chemical and environmental signals to find us, can we use botanical compounds to make ourselves a less attractive target?

Let's build the arsenal and take a look at what the science tells us.

WATCH THE BLOOD HUNTERS - How Mosquitoes Find You — And How to Fool Them

In the video above, we take a closer look at how mosquitoes locate their targets and then put five DIY botanical preparations to the test. The recipes below provide the ingredient lists, preparation instructions, and additional background information for each of the five preparations featured in the video.

THE BONER'S BOTANICALS DIY MOSQUITO ARSENAL

Before getting into the recipes, there is an important distinction to make. These preparations should not be considered equivalent to commercially tested mosquito repellents. Natural ingredients can have interesting insect-repelling properties, but their effectiveness can vary substantially depending on the mosquito species, concentration, formulation, application, temperature, perspiration, and exposure to water.

Some of the ingredients used in these recipes have been studied in laboratory or field conditions, while others are primarily included because of their skin-care or formulation properties. The fact that an ingredient has demonstrated mosquito-repelling activity in a scientific study does not necessarily mean that a homemade mixture containing that ingredient will provide the same level or duration of protection.

With that in mind, let's get to work.

1. THE CITRUS COOLER

Fresh Aloe Vera, Lemon, Peppermint, and Witch Hazel

The Citrus Cooler combines fresh aloe vera, fresh lemon juice, peppermint essential oil, and witch hazel to create a botanical preparation that brings together skin care and several plant-derived ingredients of interest for mosquito defense.

Aloe vera has been used for thousands of years as a traditional skin-care plant. Its gel provides a smooth, water-rich base for the preparation and can leave the skin feeling cool and hydrated. While aloe itself should not be presented as a proven adult mosquito repellent, it can make an interesting addition to a topical botanical formulation.

Next comes a little citrus firepower in the form of fresh lemon juice. Research involving citrus oils has demonstrated mosquito-repelling activity associated with certain compounds found in citrus plants, although that evidence should not be interpreted as proof that applying ordinary lemon juice to the skin provides reliable mosquito protection.

Peppermint brings another interesting botanical component to the formula. Research has demonstrated mosquito-repelling activity associated with peppermint oil under laboratory conditions, although the results depend on concentration and formulation.

Finally, we add witch hazel. Witch hazel has a long history of use in skin-care preparations and is commonly used to cleanse the skin and provide a mild tightening or refreshing sensation.

Put it all together and you've got what we like to call The Citrus Cooler—a botanical skin preparation designed with mosquito warfare in mind, with a little skin therapy on the side.

Recipe - 2 oz Amber Glass Spray Bottle

Ingredients:

• Fresh aloe vera gel - 2 Tbsp

• Fresh lemon juice - 2 Tbsp

• Peppermint essential oil - 10-15 drops

• Witch hazel - Fill to top of 2 oz glass spray bottle.  

Directions

Blend the fresh aloe vera gel until it reaches a smooth consistency. Add the lemon juice, peppermint essential oil, and witch hazel and mix thoroughly. Transfer the finished preparation to a clean spray bottle or container and shake before use.

Because this recipe contains fresh aloe vera and lemon juice and does not contain a commercial preservative system, it should be treated as a fresh preparation. Refrigerate it and discard it if its appearance, odor, or texture changes.

2. THE SPICE BOMB

Pure Vanilla, Cinnamon, Clove, and Witch Hazel

The Spice Bomb takes a completely different approach. Instead of citrus and aloe, we're heading straight for the spice cabinet with pure vanilla, cinnamon, clove, and witch hazel.

Cinnamon and clove are the ingredients that make this preparation particularly interesting from a mosquito-research standpoint. Studies have found mosquito-repelling activity associated with both cinnamon and clove oils. Clove oil is especially interesting because eugenol, one of its major naturally occurring compounds, has demonstrated insect-repelling properties.

The vanilla is included for its aroma and as part of the overall botanical formulation, but it is important not to oversell it as a proven mosquito repellent. Evidence for ordinary vanilla extract as a reliable mosquito repellent is weak compared with the research surrounding ingredients such as cinnamon and clove.

That leaves us with witch hazel to help round out the preparation.

The result is a recipe that smells considerably better than a mosquito trap and gives us a chance to put some serious spice into the battlefield.

Miss Mosquito just walked into the spice aisle.

Recipe - 2 oz Amber Glass Spray Bottle

Ingredients:

• Pure vanilla extract - 3/4 tsp - 1 tsp

• Cinnamon leaf Oil - 10-15 drops

• Clove Essential Oil - 3-5 drops

• Witch hazel - Fill to top of 2 oz spray bottle

Directions

Combine the ingredients in a clean container and mix thoroughly. Shake well before use, as the components may separate over time.

For topical use, avoid the eyes, mouth, broken skin, and irritated areas. Because essential oils and concentrated botanical ingredients can cause skin irritation or allergic reactions, patch-test a small area before applying more broadly.

3. THE BOTANICAL MOLOTOV COCKTAIL

Neem Oil, Coconut Oil, Eucalyptus, and Witch Hazel

Now we're getting into some serious botanical artillery.

The Botanical Molotov Cocktail combines neem oil, coconut oil, eucalyptus essential oil, and witch hazel. Of these ingredients, neem is particularly interesting because it has a history of scientific investigation as a mosquito-repelling botanical.

Field research has demonstrated significant mosquito-repelling activity from certain neem preparations. In one study, neem oil incorporated into coconut oil provided substantial protection against several mosquito groups under the conditions tested. Those results are interesting, but they should not be interpreted as a guarantee that a homemade preparation will provide the same protection.

This is where formulation becomes important. The concentration of an active botanical compound, the carrier used, the mosquito species, and the conditions under which the product is applied can all influence performance.

Coconut oil serves as an oil-based carrier in this preparation, while eucalyptus contributes another aromatic botanical component. Witch hazel helps create a more usable topical preparation.

The end result is our Botanical Molotov Cocktail—no explosives required, just a little botanical attitude.

Recipe - 2 oz Amber Glass Spray Bottle

Ingredients

• Neem oil - 1-3 tsp (2-10%)

• Coconut oil 1/2 tsp

• Eucalyptus essential oil - 15 drops

• Witch hazel - Fill to top of 2 oz spray bottle

• Optional - Add 5 drops of Lemon Eucalyptus (creates nice citrusy blend).

Directions

Combine the oils and witch hazel thoroughly. Shake well before each use because oil and water-based ingredients naturally separate.

Apply the preparation only to appropriate exposed skin and avoid the eyes, mouth, broken skin, and irritated areas. Patch-test before broader application.

4. OPERATION: SMOKE-OUT

Cinnamon, Vapor Rub, and Smoke

This next one takes mosquito warfare away from the skin and into the surrounding environment.

Operation: Smoke-Out uses cinnamon and vapor rub to create an aromatic smoke zone. The concept is simple: instead of applying a botanical preparation directly to your skin, we're creating an aromatic environment around the area where you're trying to discourage mosquitoes.

There is an important scientific distinction here. Cinnamon and some of its compounds have demonstrated mosquito-repelling activity in research, but that does not mean ordinary household smoke has been scientifically established as a specific or reliable mosquito-repellent treatment. This preparation is better viewed as an experimental environmental tactic than as a proven substitute for an EPA-registered repellent.

Because this method involves heat, flame, and smoke, safety is particularly important. It should only be used outdoors, away from flammable materials, and in accordance with applicable fire restrictions. Never leave a flame or smoldering material unattended.

When the smoke begins to roll, however, the Boner's Botanicals battlefield has officially entered the smoke zone.

Miss Mosquito, your radar just went dark. Time to find another neighborhood.

Important Safety Note

Never use a flame or smoldering material indoors or near combustible materials. Follow local fire regulations and use appropriate fire-safety precautions.

5. THE VAPOR ATTACK

Peppermint, Lemon Eucalyptus, and Tea Tree

For the final weapon in our botanical arsenal, we're taking the fight into the air with The Vapor Attack.

This preparation combines peppermint, lemon eucalyptus, and tea tree essential oils in an ultrasonic diffuser. Essential oils contain volatile compounds that readily disperse into the surrounding air, which makes them particularly interesting for an aromatic approach to mosquito defense.

Peppermint has demonstrated mosquito-repelling activity in laboratory research, while various eucalyptus-derived compounds have also been investigated for insect-repelling properties. Tea tree oil contains naturally occurring compounds that have demonstrated insect-related activity as well.

However, there is an important distinction when discussing lemon eucalyptus. Pure lemon eucalyptus essential oil is not the same thing as an EPA-registered repellent containing oil of lemon eucalyptus or PMD. Those commercially formulated products have undergone specific safety and efficacy testing, while a bottle of pure essential oil has not necessarily undergone the same testing.

For that reason, The Vapor Attack should be presented as a botanical aromatic experiment rather than as an equivalent replacement for a tested mosquito repellent.

And when the vapor starts rolling...

Well, let's just say Miss Mosquito may want to bring a cough drop.

Recipe

Ingredients

• Peppermint essential oil

• Lemon eucalyptus essential oil

• Tea tree essential oil

• Water

Directions

Add the essential oils and water to an ultrasonic diffuser according to the manufacturer's instructions. Use the diffuser in a properly ventilated space and follow the manufacturer's recommendations for cleaning and operation.

Never ingest essential oils, and use caution around children and pets because some essential oils can be hazardous to animals and young children.

THE BOTTOM LINE

There is no single botanical ingredient that makes every mosquito disappear, and there is no one-size-fits-all approach to mosquito defense.

Aedes aegypti, Aedes albopictus, and Culex quinquefasciatus have different behaviors, habitats, feeding patterns, and geographic distributions. The same botanical preparation may perform differently against different mosquito species, and the concentration and formulation of an ingredient can have a major impact on its effectiveness.

The research surrounding botanical repellents is promising in some areas, but it is also highly variable. Some ingredients have demonstrated meaningful mosquito-repelling activity under laboratory or field conditions, while others have considerably less evidence behind them.

That is why it is important to distinguish between an interesting botanical ingredient and a proven mosquito repellent.

If you're in an area where mosquito-borne disease is a significant concern, the CDC recommends using EPA-registered insect repellents according to their labels. These include products containing active ingredients such as DEET, picaridin, IR3535, oil of lemon eucalyptus/PMD, and 2-undecanone.

The recipes in this article are intended to explore botanical ingredients, traditional plant-based approaches, and DIY formulation techniques. They are not guaranteed to prevent mosquito bites or mosquito-borne disease.

The best mosquito is still the one that never gets the opportunity to bite you.

REDUCE THE BATTLEFIELD

Repellent is only one part of mosquito defense.

One of the most effective things you can do around your home is eliminate places where mosquitoes can reproduce. Regularly empty or change water in containers, clean gutters, dump standing water from outdoor objects, and pay attention to anything capable of holding rainwater.

A mosquito doesn't need much water to get started.

That forgotten flowerpot saucer, bucket, tire, birdbath, or toy left outside after a rainstorm can become part of the problem.

In other words, sometimes the best mosquito defense isn't a spray bottle.

It's a five-minute walk around the backyard.

SAFETY FIRST

Natural does not automatically mean harmless. Essential oils, concentrated botanical extracts, and homemade preparations can cause skin irritation, allergic reactions, or other adverse effects.

Always patch-test a topical preparation on a small area before broader use. Avoid the eyes, mouth, mucous membranes, broken skin, and irritated skin. Do not ingest essential oils, and keep concentrated essential oils away from children and pets.

Homemade preparations containing fresh ingredients have a limited shelf life because they generally do not contain the preservatives used in commercial products. Refrigerate fresh preparations when appropriate and discard them if they develop an unusual odor, appearance, or texture.

Any preparation involving flame, heat, or smoke should be used outdoors with appropriate fire-safety precautions and in compliance with local fire regulations.

For situations where protection against mosquito-borne disease is particularly important, use an EPA-registered repellent according to the product label.

FINAL THOUGHT

Mosquitoes may be tiny, but they're remarkably sophisticated hunters. They have evolved an impressive sensory system that allows them to locate their targets in a complex environment.

But understanding how they operate gives us an advantage.

We can eliminate their breeding sites, reduce the places where they hide, use physical barriers, and choose repellents that have been tested for effectiveness.

And, if you're the DIY type, you can experiment with the remarkable chemistry found in the plant kingdom.

That's what Boner's Botanicals Mosquito Warfare is all about.

Understanding the enemy.

Exploring the science.

Building the arsenal.

And having a little fun while we fight back.

Frequently Asked Questions

How do mosquitoes find you?

Mosquitoes use a combination of sensory signals to locate their next blood meal. Carbon dioxide from our breath can alert them to a nearby host, while body heat, skin odors, moisture, and other chemical cues help guide them the rest of the way. Once a mosquito gets close, these signals work together to help it pinpoint a suitable place to land and feed.

Why do mosquitoes seem to bite some people more than others?

Mosquito attraction varies from person to person. Differences in body odor, skin chemistry, carbon dioxide production, heat, and even the microorganisms living on the skin can influence how attractive someone is to mosquitoes. This is one reason why two people standing next to each other can experience very different numbers of bites.

What attracts mosquitoes to humans?

The biggest clues include carbon dioxide, body heat, moisture, and the collection of chemical odors produced by our skin and sweat. Different mosquito species can respond differently to these signals, but together they create what amounts to a biological homing beacon for a hungry female mosquito.

How far away can a mosquito detect a human?

Mosquitoes can detect carbon dioxide from relatively far away and use it as an initial clue that a potential host is nearby. As they get closer, they rely increasingly on additional signals such as body odor, heat, and moisture. There isn't one fixed detection distance because it varies with mosquito species, wind, environmental conditions, and the strength of the host's signals.

What time of day are mosquitoes most active?

It depends on the species. Aedes aegypti and Aedes albopictus are commonly active during the daytime, with increased activity around dawn and dusk. Culex quinquefasciatus, on the other hand, is primarily active from dusk through the night. Knowing when a particular mosquito is most active can help you time your defenses more effectively.

What is the difference between Aedes aegypti, Aedes albopictus, and Culex quinquefasciatus?

These three mosquitoes have different habits and behaviors. Aedes aegypti, the yellow-fever mosquito, is strongly associated with human environments and commonly breeds in small water-holding containers. Aedes albopictus, commonly called the Asian tiger mosquito, also breeds around residential areas and is generally active during the day. Culex quinquefasciatus, the southern house mosquito, is primarily a nighttime biter and is associated with birds as well as mammals. Their geographic ranges also overlap in many parts of the southern United States.

Do essential oils really repel mosquitoes?

Some essential oils and their individual compounds have demonstrated mosquito-repellent activity in laboratory and field research. Peppermint, cinnamon, clove, neem, and certain eucalyptus preparations have all been investigated. However, results can vary considerably depending on the mosquito species, concentration, formulation, and application. A homemade essential-oil mixture should not automatically be considered equivalent to a tested commercial repellent.

Does lemon eucalyptus repel mosquitoes?

There is an important distinction here. Oil of lemon eucalyptus (OLE) and PMD, a component derived from OLE, have been studied as mosquito repellents and are used in some registered repellent products. Pure lemon eucalyptus essential oil is not the same thing, and it should not be assumed to provide the same protection. For reliable bite protection, use an EPA-registered product according to its label.

What is the best natural mosquito repellent?

There isn't one natural ingredient that works best against every mosquito under every condition. Neem, peppermint, cinnamon, clove, and certain eucalyptus compounds have shown interesting results in research, but their effectiveness and duration can vary. For protection against mosquito-borne disease, the CDC recommends using an EPA-registered repellent according to the product label.

How can I reduce mosquitoes around my home?

One of the most effective strategies is to eliminate places where mosquitoes can reproduce. Empty standing water from buckets, flowerpots, toys, birdbaths, clogged gutters, and other containers regularly. Keep water-holding containers covered or emptied whenever possible, and maintain screens and other physical barriers. Sometimes the best mosquito defense isn't another bottle of repellent—it's removing the mosquito nursery from your backyard.
