Why do slugs come inside?

If you’re wondering why you keep finding slugs in the house, it’s because they have an amazing sense of smell. They may be attracted to food in your kitchen, pantry or even pet food.

Where do slugs come from?

Slugs have no bones. In fact, they don’t even have a hard shell like an insect. This means they are capable of squeezing through tiny cracks up to half its size. They can also travel up vertical walls and surfaces and upside down. This allows them to get in through holes drilled for water, gas pipes, electric wiring, joints along walls, dryer ducts and more.

How to prevent slugs in your house

  1. If you’ve found slugs in kitchen cupboards or trails on pantry shelves, you can use these tips to get rid of slugs in the house and prevent a future slug infestation.

  2. Wear old clothes and gloves when doing this type of work.

  3. Follow the slug trails to find their entry points. Check joints, holes and gaps along walls, door frames, pipes and under cabinets.

  4. Keep children and pets out of the way when filling the holes.

  5. Place plastic tarpaulin, old newspapers or an old sheet below the area you are working.

  6. Use an old rag to catch any excess filler which might ooze out of the nozzle as you work.

  7. For larger cracks, use expanding foam. 

  • You can buy polyurethane foam in a can, which makes it easier to use. 

  • This won’t just keep out slugs; it keeps out the wind, noise and rodents, too!

  • Use up the can while it is fresh as once it begins to harden, it will block the nozzle.

  • Once the foam has hardened in the crack, trim off any excess with a serrated knife or hack saw.

If the entry point is a smaller crack or opening, use silicone sealant.

  • Purchase a squeeze tube as this will be much easier to use.

  • Simply squeeze a bit of sealant into any holes you find where slugs can enter.

  • You can also use it to fill in spaces between floorboards, door frames and timber joints.

How to get rid of slugs in your house

Once you’ve sealed their entrances, you’ll want to get rid of any slugs which are already in your house. Here are a couple of tips for getting rid of these slimy pests.

  • Use slug bait. These are a great way to get snails and slugs alike to come out of their hiding places so you can get rid of them. Most baits are developed to be tasty to slugs and non-toxic to pets and children, but always check the manufacturer’s details on the label.

  • Lay out some salt. Salt is an easy way to kill off slugs, but it isn’t the most humane way of getting rid of them! Be aware if you are laying out a line of salt it could also affect nearby plants.

Can slugs damage my property?

Slugs can indeed cause damage to various aspects of your property. These slimy creatures are known for their voracious appetite and can feed on a wide range of plants, including flowers, vegetables, and ornamental foliage. They can devour leaves, stems, and fruits, leading to unsightly and damaged vegetation. Slugs can also leave slimy trails on outdoor surfaces, which can be difficult to clean. Moreover, they can find their way into homes and cause damage to carpets, furniture, and stored items. Taking preventive measures like using barriers, removing debris, and employing organic slug control methods can help minimise their impact on your property. With these top tips you will not only be able to get rid of slugs but also prevent a future slug infestation in your house.
