The first step involves clearing out the rodents by de-scenting, decontaminating, and finally destroying. Finding and de-scenting is crucial to combating your rodent problem because once the scent is eliminated the rats will have no one place to congregate. Most professionals will use rat poison or rat traps to catch and kill the actual rats that are within your home. What makes professionals crucially different from homemade solutions to your rodent problem is rat proofing your home. Finding out how the rodents are coming into your home and then closing these entrances, is the most important step in how professionals remove rats from your home.
