I was very pleased with the Bug Zapper service. The serviceperson had the appropriate equipment to brush down the exterior of my house and then sprayed the entire foundation. The spiders and sow bugs that populate the foundation dropped dead right before my eyes. I haven't seen a live bug in several days. He will return within 60 days for a second application. It is so nice that those tiny spider webs are now gone and the house looks very clean. I highly recommend this business.
