Outdoor Fogging: Insecticides, Foggers
To kill mosquitoes, flies, biting flies, gnats, fleas and other annoying pests outdoors, thermal or cold foggers can be used. There is a wide variety of insecticides to choose from but not every fogging material can be used in thermal foggers. If you use an electric cold fogger indoors and outdoors, choose a fogging solution that is labeled for such uses. When using a thermal fogger, choose a fogging solution that will burn properly.
Choosing a Fogger
A cold fogger is an electric fogger that has the obvious
disadvantage of needing an electrical outlet and extension cord to power the unit, but it
does not produce fog or smoke with a heat coil (as does a thermal fogger.) If
treating a patio or small outdoor area is all the work needed around your home, an
electric fogger will work. Many electric foggers have a knob or valve for adjusting
droplet size. These units are usually designated as a ULV type of machine. An
example of a ULV fogger is the B&G Flex-A-Lite fogger.
A thermal fogger is a unit that has a heating coil used
to turn your liquid insecticide into a very light mist or smoke. This is the most
popular type of fogger used by home owners or individuals that want to rid their yard,
patio, gazebo (or other such areas) of mosquitoes, flies and biting insects. The fog
can be directed at grass, shrubs, small trees, cook-out areas, under picnic tables or
other areas that need to be mosquito and insect free.
Choosing Fogging Solutions, Fogging Concentrates
Mosquito, Insect Killer for Thermal Fogger
A thermal fogging machine uses heat to transform your liquid insecticide into a fog or smoke. The product you choose must have properties that allow it to burn. Resmethrin Fogging Solution contains .2% Resmethrin and is manufactured for use in your thermal fogger. Another option is to use Ready to Use .5% Fog, a material that contains .5% pyrethrins. This material is cleaner and can be used indoors and outdoors. For a longer residual (on outdoor vegetation) add 2 ounces of Permethrin-10 (a synthetic pyrethrin insecticide concentrate) to your fogging solution to be used in thermal foggers. Permethrin-10 can be added to outdoor fogging solutions. Resmethrin (a man-made or synthetic pyrethrin) and natural pyrethrins have a quick knock-down of targeted flying insect pests but leave little to no residue. If you desire a longer residual, add Permethrin-10 to your solution.
Mosquito, Insect Killer for Cold Fogger
Cold foggers do not require a solution which will burn. Resmethrin Fogging Solution and Ready to Use .5% Fog can be used in cold foggers when treating for outdoor pests. When fogging indoors, do not use Resmethrin products. Pyrethrin products are usually labeled for indoor use. Use Exciter or Ready to Use .5% Fog for your indoor applications. Exciter is a very high concentrate of pyrethrins that is suitable for large jobs. Mix 1 to 4 ounces Exciter per gallon to make your own indoor pyrethrin fogging solution. If you do not want to mix your own, use Ready to Use .5% Fog. Permethrin-10 can be added to these fogging solutions for outdoor applications, only.
