We seal all the construction gaps with a treated foam spray that blocks any and all critters from entering your home. After the sealing process is complete, you will benefit in two ways. Poison is a very bad idea. One, it's inhumane and two if an animal ingests the poison and dies in your house you won't know where but you will know by the smell that you won't be able to live with. Trying to find a dead animal in your house can be very costly. At Wildlife Roundup, we fix the problem so you won't have to pay, spray or contract for pest control service ever again.
