1. Why Crawl Spaces Attract Pests

Crawl spaces are often out of sight, which unfortunately makes them ideal environments for pests. Understanding how to control pests in crawl spaces begins with knowing why these areas are so appealing in the first place.

1. Crawl spaces tend to be dark, quiet, and undisturbed.

2. Moisture accumulation creates a perfect habitat for insects.

3. Small openings around foundations allow easy entry for rodents.

Many homeowners only realize there is a problem when it spreads into living areas. By then, the issue may already be extensive and costly.
