Not all visitors are welcome, and not every visitor enters through the front door. Homeowners who have experienced a close encounter with a raccoon, squirrel, bird or snake in their home know this all too well.

To prevent critters from invading your home, take precautions to keep them out in the first place. It's a much easier approach than dealing with them after they have taken up residence in your home. The damage caused by home-invading animals can be extensive, from destroyed electrical lines to droppings that can ruin insulation and cause airborne illnesses.

When selecting an animal removal company to help you assess areas around your property that could be vulnerable to animal intrusions, take these eight areas into consideration:

1. Roof: If your roof has deteriorated due to harsh weather conditions or other issues, small areas could be exposed to animal entry without your knowledge.
2. Soffit vents/fascia: An inspection of soffit vents and fascia are crucial, as small animals often use gaps in these areas to gain entry into the attic.
3. Exterior structure: Whether your home has siding, brick or wood, it can be vulnerable to wildlife if there are any damaged areas. For example, wood damaged by moisture can make it easy for animals to gnaw a hole into the structure and into your home.
4. Foundation: Inspections around the foundation of your home could expose cracks or other damage that could allow critters enough space to enter. It is also important to check spaces around or below your porch or deck.
5. Chimney/fireplace: The installation of a chimney cap is critical in keeping your home protected against animal intrusions.
6. Attic: Make sure the exhaust fan opening for your attic is properly installed and covered.
7. Window wells: Ensure your window wells have been covered with commercial grates.
8. Landscaping: A reputable landscaping service should be able to provide solutions that will deter wild animals from your property, such as trimming nearby tree limbs to prevent squirrels and raccoons from having easy access to your attic. Treatments to the lawn also can keep it free of grubs and other insects that could attract hungry critters.
