I hired GrassRoots this year for their mosquito treatments as their price was better than others. We have not regretted it! Every time we went outside we always had mosquitos hovering around us on the new porch we built. We have tiki torches, which helped, but fires burning all around us was the last thing we wanted on an already hot and humid Georgia summer day. I went out last weekend to grill out and immediately noticed the lack of mosquitos...and with no lighting a single torch! Were sold. Plan on doing this again next year!
