ProStar has sprayed my home for several seasons now to protect my family, and guests from bees and those nastier wasps and yellowjackets and the like. I appreciate the fact their technician gets into very specific nooks and crannies of my yard. For instance, around a built-in grill and around a pool house. IF a determined swarm of a stinging pollinators decides to build a nest, despite the preventative measures taken, ProStar will come back out and spray the area, no questions asked. They are very good!
