    To effectively get rid of carpenter ants, you should first identify and eliminate their nest, which is likely in or near your crawl space. Here are the steps you can take:

    1. **Inspect the Area**: Look for signs of ant activity, such as frass (sawdust-like debris), and check for moisture issues. Carpenter ants are attracted to damp wood, so fixing any leaks is crucial.

    2. **Remove Food Sources**: Keep your bathroom clean and free of food debris. Store food in airtight containers and clean up spills promptly.

    3. **Seal Entry Points**: Check for cracks and gaps in your home’s exterior and seal them to prevent ants from entering.

    4. **Use Bait and Insecticide**: You can use carpenter ant bait stations, which contain poison that worker ants carry back to the nest. Look for these at local hardware stores.

    5. **Consider Professional Help**: If the infestation persists or is extensive, hiring a licensed pest control professional is advisable. Costs typically range from $100 to $300 depending on the severity of the infestation and your location.

    Your next step should be to get 2–3 local quotes on Handyman.com to find a pro who can help assess and eliminate the problem effectively.
