How long does it take Bifen I/T to work on mosquitoes?
I sprayed bifen I/T all over my lawn, bushes, and trees during the heat of the day as recommended for mosquitoes. However, after sunset mosquitoes were all out again feasting on my family. did I use the right product to kill mosquitoes.
Bifen IT is to give off a residual to last up to 30 days outdoors for the insects that come into contact with the residual left behind. With mosquitoes this will take some time to see any results because they are flying insects. It can take time to see any result after application.
