This small business out of the Brookfield-Waukesha area has a lot going for it! They were friendly,courteous,and they offer effective skeeter spraying (they say it kills a LOT more than just mosquitos) at affordable prices compared to other local mosquito killers. I noticed they take more time and put down more pesticide than other outfits who always seem to be rushing.A little rain won't hurt the effectivness of their spray job but a DELUGE of rain after spraying probably will cut down on the length of time the juice is effective. Usually one spraying a month does the job in my yard. This is a small two person opperation so you should call them early if you want your yard/business sprayed by a certain date. I can recommend them to anyone except maybe people with very SMALL yards since the little stingers can fly into your yard from a close, untreated yard. Go ahead and use Amscray if you want to enjoy our short Wisconsin summers!
