…so avoid spraying flowers. I was under the impression that these insecticides have a residual effect & that's why you only need to apply a few times a year to kill. If that's 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 didn't have any more of my beneficials. We are organic but didn't know there was swampland when we looked at the house w/ snow on the ground last year. I didn't even plant any more flowers for fear I'd 'entice them to their doom'.
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.
