How to get rid of No See Ums
No see ums are a nuisance because of their tiny size. They can fit through spaces in typical window screens and so people who live near marshes or swampy environments may see No see ums enter the home frequently. True infestation indoors is impossible because they are unable to breed without a moisture source, nor can they develop without a moisture source. Therefore, the best ways to control infestations are to target nests that are located outdoor and close to your home.
You can prevent No see ums from entering the home by creating a barrier around the perimeter of your home. Using a liquid concentrate insecticide like FenvaStar EcoCap or FenvaStar Plus-Esfenvalerate that is diluted with water and sprayed with the Chapin Gallon Sprayer around the perimeter of your house, will help prevent entry of the No see ums. You should pay close attention to your window screens, window frames, door frames and screens, and any crack or crevice that may serve as an entry point for these insects. If possible, the screening should be changed to a super-fine mesh to keep No see ums from entering through these areas.
Non-residual misting concentrates like Riptide Waterbased Pyrethrin ULV and EcoExempt MC & EcoEmulsifier can also be applied in areas of heavy infestation for a fast knock down and instant gratification. Archer IGR is recommended to be added to the solution so that the reproduction of No see ums can be controlled. A fogger or an automatic misting machine can be used to dispense the solution.
No see um stragglers may enter the home at any given time during the summer season. If the flies have entered, aerosol sprays like Microcare Aerosol Spray may be applied indoors.
You may also want to consider creating “shields” from the inside using the liquid concentrate insecticides to focus on windows and door frames.
