Jay J, sorry I thought the question was built in. What we have is a home in northern Mi. that is located on 2 acre parcels on a lake. One neighboring home has similiar problems, but what I am asking is " How does one get rid of these problems ". We have used sprays and foggers, but these are a temporary remidy. Is there some type of chemical that I can use that would make an insect carry back to a "HOME" nest and kill the originator. Thanks!!!
