What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Inspect the Crawl Space

Begin by thoroughly inspecting your crawl space for signs of rodent activity. Look for droppings, gnaw marks, and nests, as these are clear indicators of a rat problem.

2

Identify Entry Points

Check for any gaps or holes in the foundation, vents, or around pipes. Rats can squeeze through surprisingly small openings, so be thorough in your search.

3

Eliminate Food Sources

Remove any potential food sources that may attract rats, such as pet food, garbage, or stored food items. Ensure that your crawl space is clean and free of debris.

4

Seal Entry Points

Use steel wool or metal mesh to seal any identified entry points. This can help prevent further access by rats looking for shelter.

5

Set Traps

Place traps in areas where you've noticed rat activity. Consider using snap traps or live traps, and be sure to follow safety precautions.

6

Monitor for Activity

After taking these steps, regularly check for new signs of rat activity. If you still notice signs of infestation, it may be time to call in Pure Maintenance Down Under for professional assistance.
