A huge construction project nearby stirred up an incredible number of rats in the dead of winter, and of course the rodents wanted safe, dry places to live. Human houses! What else? In our case, we could hear them in our walls and ceilings, and we found droppings and nest-making evidence in the attic. We started with two other pest control outfits, and their efforts at trapping helped a bit, but not enough. We feel lucky to have found All Natural because they have the professional know-how, the energy, and the attention to detail required to actually win this war. A really nice man -- a biologist!-- from All Natural spent an entire day sealing off our house to prevent rats from entering. He found openings the other two outfits had missed. After All Natural arrived, the noises stopped almost at once. No kidding. In case of pest problems in the future, All Natural guarantees to help us over the next year. We recommend this company without reservation.
