These guys are GREAT!!! I had the WORST problem with fleas in my house. I bombed 3 times and used industrial pesticide spray from the feed store and sprayed twice and the fleas only got worse. Guaranty came out and sprayed the yard and house, the fleas came back. Guaranty stuck with us and came back out and sprayed again (no charge). The fleas came back. Guaranty came out a third time (no charge again). The third time was the charm for these super fleas. Haven't had a problem since. They stuck with us through the problem and so I would recommend them to anybody.
