I was impressed with Critter Control's responsiveness and professionalism. The company sent Doug to my house each time and I felt like he became a friend after a while because he was so pleasant and easy to work with. He showed up on time, with a smile and ready to help. He got rid of all the raccoon activity in my attic and he found and sealed the access points and other holes that I hadn't even noticed. He did a very professional job in placing mesh over my vents and closing up the other holes. I was very happy with the results and have not had raccoons since. The rats are a different story. I heard the noise in my walls and called Critter Control. They came out and placed rat baits around the exterior perimeter of my house. It helped but after a month, I still had just a little noise in my walls. I called another company, Bob Jenkins, just to see if they could get rid of the remaining rats. A Bob Jenkins serviceman came out, was nice and professional, and they installed rat baits like Critter Control had done. After a month, I still had evidence of rats (one of my cats killed a rat in my backyard, and I could still hear the noise in the wall). Bob Jenkins's company also sealed up a couple of holes they found, but the work wasn't nearly as professional and nice looking as what Critter Control had done. I think rats are extremely hard to get rid of permanently. Both companies said rats could fit through a 1/2 inch hole, and they can burrow under the house. I will happily use Critter Control again for any of my future rodent issues! I recommend them to you as well.
