Rodent Control in Crawl Spaces

A crawl space makes an inviting home for rodents, such as mice and rats, as well as many other pests. This poses numerous problems for homeowners. Rodents contaminate food and can make people sick. They leave urine and fecal droppings that contain germs and cause allergic reactions in some people. Even worse, rodents can cause house fires by gnawing on wires.

Get the Facts: Baby rodents mature in 2-5 months and can produce up to six litters per year. A pair of rats and their offspring can multiply to 278 rats in a single year!

Why rodents like crawlspaces

Signs You Have Rodents

  • Scratching or scurrying noises in the walls or ceiling, especially at night
  • Piles of dirt or rodent excrement
  • Foul odors
  • Signs of tunneling
  • Holes chewed in walls
  • Sightings

Rodents are attracted to crawl spaces because they are warm, damp, and protected from the elements. In addition, they are typically near food supplies (such as trash), and are not usually monitored frequently by homeowners. Crawl spaces supply plenty of entry points for pests, including gaps between the foundation and framing, spaces under doors, penetrations for wires and pipes, vents, and tunnels through dirt floors.

The CleanSpace® solution

Controlling Rodents

  • Do not store food in your crawl space Rodents will chew through a wooden cabinet to get to food.
  • Eliminate sources of water and lower humidity Rodents, many insects, and mold and fungi prefer areas with high humidity
  • Seal all cracks and openings Many pests follow the path of least resistance. Don’t make it easy for them to get into your home!
  • Add a barrier to dirt floor crawl spaces. A thin slab, commonly called a rat slab, is commonly used to stop rodents from tunneling into your crawl space.
  • Keep a trap in your crawl space. Set and bait it when you find evidence of rodent activity.
  • Keeping a cat on patrol will also help!

A CleanSpace® crawl space encapsulation begins with the removal of organic material that would otherwise support pest life. If rodents are present, an exterminator is called in to eliminate them before the work begins. A crawl space waterproofing system, if necessary, is installed prior to encapsulation as well.

The encapsulation process then makes your crawl space look a lot less like the rodent motel it did before. The water has been “turned off” thanks to waterproofing and dehumidification, deterring rodents that prefer damp conditions. Pest entryways, such as gaps and holes, are carefully sealed with spray foam insulation. Ill-fitting vent covers and hatchway doors are replaced with air-tight vent covers and hatchways. Finally, CleanSpace® crawl spaces are easier to monitor for rodent activity. If a rodent does manage to gain entry, it will be easier to spot the evidence and set a trap.

Get the Facts: Rodents possess soft cartilage that allows them to squeeze through very small openings. A mouse for example, can enter through a hole the size of a dime; a rat can enter through a hole the size of a quarter.
