They keep appearing in my basement and I have not located where they are coming from.
Bifen IT will kill yellow jackets but only if they land on a surface you have treated. Have you tried looking outside in the morning or early afternoon? This is when yellow jackets are most active and chances are you can see where they are going into your home which usually would be under some siding or through a small opening in brick or around a window. If you can locate their entry point then it is an easy fix. Early in the morning or late at night when the yellow jackets are not flying around and not active, you can apply Tempo Dust into the opening using a hand duster. If you can locate the entry point, then this treatment will usually kill all of the yellow jackets within 24 hours. Once there is no more activity, you want to be sure to close the opening with caulk or some other method so future yellow jackets do not try to use the same entry point.
