Do not waste your money!!!!!! 3 weeks later and we still have a bee problem. The hive is in our gutter, Bill "sprayed" the hive with a chemical then immediately sealed the space with a yellow foam. He said that we shouldn't see any more bees for a few days. There's bee activity in the same gutter area he treated and in our house. Called him a few days later and he said there's nothing else he can do, he cannot control nature or guarantee anything. Called him a week later and he agreed to come the next day-sprayed fogger in a gap then foamed again.Now we are killing up to 20 bees a day in our house while we wait on another company to come out and fix his work. The only reason he was rated one star is because the site wouldn't let me proceed to type a review. $145 down the drain.
