Öso avoid spraying flowers. I was under the impression that these insecticides have a residual effect & thatís why you only need to apply a few times a year to kill. If thatís the case, how does it NOT kill the beneficials that happen to land on leaves, grass to rest? We have swampy wooded acreage w/ mosquitoes but we also have dragonflies, butterflies, & bees. When we broke down & used a company (cyfluthrin/ bifenthrin) after trying TONS of organic options, I noticed that I didnít have any more of my beneficials. We are organic but didnít know there was swampland when we looked at the house w/ snow on the ground last year. I didnít even plant any more flowers for fear Iíd Ďentice them to their doomí.
Bifen IT is not labeled for beneficial insects, but it has the potential to kill them if they come in contact with the treated area.
