Homemade mosquito fogger

Want to make a homemade mosquito fogger? A mosquito fogger uses a heat source to send a mosquito repellent solution into the air as a mist or smoke. Fogging or misting works best for small areas, such as patios, but can be used on large areas with the homemade mower type foggers. Like all foggers and misters they are not very effective on windy days.

There are several different types and we will review the main types of homemade foggers and hopefully you will find the right project for your situation. The easiest homemade mosquito foggers are those that are made from a humidifier. There is very little difference in most of the commercial foggers, like the Mosquito Sentry Units and a cold air humidifier or diffuser. Fill the units with an all-natural solution that is mostly water and the unit will change the solution in to a mist. There are several essential oil recipes on this site to choose from. Do not use hot air type humidifiers, the heat can degrade the essential oils. Cold foggers use less product than thermal foggers.
For those of you that are good with tools, there are homemade mosquito foggers made from attachment to the exhaust of push or riding mowers. Regardless of what type of fogger you make, fogging is most effective at dusk, when mosquitoes are most active.

First, let’s talk about what we suggest you don’t do. There are homemade mosquito fogger recipes out there that involve mixing and melting 3 parts potassium nitrate with 2 parts granulated sugar and pouring the gooey mixture into aluminum foil and letting it dry. You can then put the foil packages outside and in the heat and let the produce fumes that will repel mosquitoes. Some of the recommendations are much more hazardous, cooking the mixture on a camping stove or grill. When heated the sugar and potassium produce a thick, noxious gas that is poisonous to mosquitoes, humans, pets and beneficial insects which we don’t recommend.

For the mechanically minded, the article on ehow Build Your Own Thermal Mosquito Fogger lists the materials you will need to convert your mower into a thermal fogger and has detailed instructions. There are several good videos showing how to make a mower-mosquito fogger, here is an excellent one.

Another one to check out is How to build an insect fogger. Both of these articles explain how to add a pipe to your mower that will drip the mosquito repellent solution on to your exhaust pipe. Like the aluminum foil foggers, these thermal foggers can be hazardous to your own health. In this article Homemade fogger Kills Mosquitoes the fogger is made out of an old power washer. Like he says in the article, any engine on a frame with wheels will work. He mounted a small plastic tank on the handles of his pressure washer. He fitted the plastic tank with a valve and copper tubing that he ran down to the pipe on the engine block. He fills the plastic tank with insecticide. It flows through the copper tube, is preheated as it flows around a steel pipe on the exhaust, and then vaporizes when it drips into the muffler.

There are several insecticide products available for foggers that you can use in your homemade mosquito fogger. We suggest buying a product made for foggers. There are several brands of chemical insecticide to choose from, such as Black Flag Fogging Insecticide. For nontoxic solutions, there's Natural Pyrethrum Concentrate, which is all organic and made from a relative of the chrysanthemum. Another alternative for a natural insecticide is a Neem oil concentrate, which is safe for use in all residential landscapes when diluted.

If you make your own insecticide for your fogger, we suggest staying away from using diesel. A mix with permethrin (to kill) and PBO (to stir the mosquitoes up) with mineral oil works for many people. Another mix includes 50ml of Permectrin2 with 1 gallon of mineral oil. If you have a bad mosquito problem, are allergic to mosquito bites, or have other insect issues like midge flies, buy a concentrate that is at least 30% Permethrin and 60% PBO-8. You can mix 10 ounces of this with a gallon of oil and you will have a gallon of chemical that is then reduced to 3% Permethrin and 6% PBO-8.

In summary, we suggest using a cold diffuser with an essential oil solution. This is the healthiest version of a homemade mosquito fogger. This is great for patios or screen porches or other small areas. If you are wanting to treat a large area, then by all means pick up an old mower, take the blades off and rig it up for fogging. With any motorized fogger we suggest wearing a respirator to reduce the amount you expose yourself to the chemicals.
