To get rid of mice in your drain pipes, you should:
- Set mouse traps in the areas where the mice are most likely to be present.
- Seal up any possible entry points that may allow the rodents access into your home. This includes cracks around windows and doors, as well as holes or gaps in walls or floors.
- Use a solution of bleach and water to flush out any debris from beneath sinks and behind appliances that could attract rodents.
- Place some peppermint oil near potential nesting sites, as this can help deter them from entering these areas.
Finally, call a professional exterminator if necessary for particularly stubborn infestations.
