Pests like insects, rodents, and wildlife can pose serious health risks for you and your family if they infest your home. Although there are many treatments available to remove a pest infestation once it has occurred in your home, there are preventative steps you can take to ensure they never arrive in the first place. By taking precautionary steps to prevent pests from invading your home, you will save money on future extermination costs, avoid health risks, and even improve the energy efficiency of your home. The best way to prevent pests form entering your home is to find the problem areas and treat them. If these pests cannot enter your home through these key areas, they will most likely be diverted to find another nesting place. There are many problem areas in a home where pests most commonly enter. These include cracks around your doors and windows, holes in your roof and walls, access points in the foundation, and chimneys.
