Slimy intruders: how to manage indoor slugs safely

Written by Avon Pest ControlFirst published 15 February 2025Updated 9 November 2026

Slugs indoors leave trails across carpets, tiles and skirting boards, and they are not something you want near food or pet bowls. The good news is that dealing with them safely is simple, and most of the products people reach for are not needed.

The short version

• Pick slugs up and put them outside. That is the safest and quickest way to remove them.
• Keep pet food up at night and keep dogs away from slugs, which can carry lungworm.
• Do not use salt, beer traps or slug pellets indoors. Find and close the way in instead.

Why do slugs come indoors?

• Moisture and humidity. Slugs dry out easily and head for damp spots: bathrooms, kitchens, utility rooms and anywhere with a leak.
• Food. Pet food left down overnight, crumbs and spills, and some houseplants.
• Access. Gaps under doors, around pipes, through air bricks and in cracked brickwork, especially during wet weather.

The risks of indoor slugs

Slugs are not dangerous to people, but they can carry bacteria on their bodies and in their slime, so clean any surface they have crossed where food is prepared. The bigger concern is for dogs. Slugs and snails can carry lungworm, a parasite that dogs can pick up by eating slugs or snails, or by eating or drinking from something they have been on. If your dog has eaten a slug, or you are worried about lungworm, speak to your vet.

Managing slugs indoors: safe solutions for pet owners

1. Remove them by hand. Pick slugs up with gloves or a piece of kitchen roll and put them outside, well away from the house. Checking with a torch after dark is the quickest way to catch them.
2. Clean the trails. Wipe hard floors with warm soapy water. On carpet, let the slime dry first, then brush and vacuum it out; rubbing it wet spreads it.
3. Remove what attracts them. Pick pet bowls up at night, clean up crumbs and spills, and do not leave damp cloths or washing on the floor.
4. Seal entry points. Use sealant around pipes, fit brush strips on doors and fit fine mesh over air bricks without blocking them. This is what stops new slugs arriving.
5. Reduce the damp. Run extractor fans, fix drips and dry out the damp corners they are heading for.

What not to use indoors

• Salt. It kills slugs slowly and painfully, damages flooring and is harmful if pets lick it.
• Beer traps. Fine in a garden bed, but indoors they are messy, attract other insects and can tip over.
• Slug pellets. They are made for gardens, not for use inside the house, and are a risk to pets and children.
• Eggshells, coffee grounds and copper tape. Garden trials have found these barriers make little difference, and indoors they just make a mess.

Call in the professionals

If slugs keep appearing after you have sealed the obvious gaps, we can trace where they are getting in and recommend proofing for those points. If the cause turns out to be a leak or damp in the structure, the right person to fix it is a plumber, builder or damp specialist, and we will tell you so rather than sell you a treatment.
