This is our 2nd year of using Mosquito Squad. We live in Oregon, WI, and Friday evening (April 3), we were sitting on our front porch and getting eaten alive by mosquitoes! We gave one call to Mosquito Squad, and Greg and Karin came out the next day to treat our yard. It is now Sunday, and I just came in from sitting on our porch this evening. I'm happy to report there were no mosquitoes! What a difference one treatment makes. Thanks Mosquito Squad!
