Josh from North Carolina writes

I've been using Bifen IT and had success early, but now 1 to 2 weeks later we're being mauled.

I also use dunks on nearby ponds. The tiger skeeters are aggressively biting in daylight just 2 weeks after I did an application of bifen. I've done 3 applications this year since March when they get going. I'm using a ULV fogger and tank mixing some pyrethrin and IG regulator, I've measured the coverage area and applied it correctly. Are they just flying through from the neighbor's yard? We're getting killed!

Answer:

Bifen IT cannot be applied via a ULV Fogger. It can only be applied via a sprayer or mister. Generally, products that can be fogged do not leave a residual. We cannot say for certain what effects fogging the product may have caused, but we would recommend spraying your next application. It is also possible that they are coming from the neighbor's yard. Insects need to come in contact with areas sprayed with Bifen in order to be affected
