So how much does it cost to rid your home of these pests? Well that depends on the size and scope of your rat infestation, and also how many areas need to be sealed up to prevent re-entry. If you were to just set traps without sealing up the entry points, that would be like swatting flies and leaving your door open. Not really going to solve the problem, is it?
Of course, some pest control operators will “treat” a rat problem with poison. The problem with this is the rats will sometimes end up dying in your walls or an inaccessible place in your home. When this happens, you may have a terrible, decaying rat smell in your home for weeks. And cutting into your walls to remove a dead animal can be quite expensive.
