Animals seeking shelter may intrude into the crawl space under your home. The crawl space is designed to give access to your home's piping and utility systems and to create an insulating gap between your house and the ground. If animals move into the crawl space, they can damage your house, create noise at all times of the day or night, cause odors, and even become aggressive to protect their new shelter. While poison may seem like a solution, it is not humane and the animal may die and decompose in the crawl space. Safer and more humane removal solutions are available.
Affix the glue boards to the plywood with the brass tacks. Glue boards are cardboard sheets covered with a tacky, glue-like substance. Small animals become stuck in the glue when they attempt to cross over the traps. Hardware stores and exterminators usually sell these traps.

Place the plywood board into the crawl space. Position the board against a wall where animals are likely to cross.
Check the traps daily. For humane concerns, do not allow the animals to remain mired in the glue any longer than necessary.
Remove the occupied trap from the crawlspace and carry it far away from the house. Be extremely cautious because the trapped animal may become aggressive.
Pour vegetable oil on and around the trapped animal. The oil will slowly break down the glue so the animal can escape unharmed back into the wild.
Place ammonia-soaked rags in the crawl space. Most larger animals are repelled by the scent of ammonia, so ammonia-soaked rags will discourage the animal from remaining in the crawl space. Place the rags along the walls and by any openings into the crawl space.
Scatter mothballs across the crawl space floor. Animals also find the scent of mothballs to be noxious. Add a few extra balls in the corners and at the openings to the crawl space.
Expose the animals to loud music and lights. Animals cherish a dark, quiet shelter, so you can drive them out of the crawl space by being a bad neighbor. Place a blaring radio and a powerful weather-resistant light into the crawl space. The light may be a portable flood lamp or a high-powered flashlight.
