I had a rat infestation in my attic about 5 ago. LOTS OF THEM. I hired my normal pest team who came out & sealed up entrances, about 13 of them. In just a few days the rats were still there, building condos as I tried to sleep. Then I heard about ALL PEST PROS - Not only did they seal up at least 20 more entrances, they removed all the old stained insulation & installed new. I also signed up for their yearly guarantee. A lot of time has passed and there have bee ZERO signs of any rodents in my attic. I HIGHLY recommend ALL PEST PROS! Kris Salter - Sand Canyon, CA.
