Yuck! Why do I have slugs in my house?  I mean not just one but a good number of them that seem to spread out everywhere in my house.

It’s one thing to fight off slugs from your garden, but it’s overwhelmingly yucking to step on them on your floor. How can I stop slugs from coming into my house?  How can I get rid of the ones already indoors?

If you face this dilemma, it’s time to learn a little more about these slugs that confidently take space in your home.

Which Slugs Are Likely To Come Into Your House?

The slug that loves to come indoors is the ‘Limacus Flavus‘, the yellow cellar slug, a medium-sized slug measuring 13cm long.  It is slender with pale mottling on a tan or a yellow, green body.

Slugs do not have bones; that makes it easy for them to slip through even the tiniest of holes in your doors or windows.

Which Slugs Are Likely To Come Into Your House

Why Do Slugs Come Into The House?

Slugs come indoors looking for something they need.  If they need warmth or shade, they will look for it in your home.  Knowing what attracts them to your house will help keep them away.  For example, the yellow cellar slug loves to eat algae and mould but can also be found eating pet food, leftovers, and compost.

This slug is attracted to dark, damp areas like vents and drains.  This creature comes in at night because it is strictly nocturnal, which means you will only see their mucous trail in the morning but not see them.

Slugs commonly infest old houses because they are likely to be cool and moist.  If you have a damp problem in your house, you should quickly sort it out to avoid slugs becoming your unwanted guests.

Pet food is another reason why slugs visit your hose.  Slugs have an excellent sense of smells that will lead them to your pet’s food or some plants that you are growing in your living room.

When the weather is hot outside, in most cases, slugs are looking to be cooled, and your house could come in the way of their search.

Remember, slugs don’t have bones and can stretch as long as 20 times their normal length to enable them to squeeze through the tiniest spaces in your house.

If you find several slugs in your kitchen or bathroom, pour salt on them; however, it will kill them. Don’t use salt on your indoor plants, as it can kill them.

Use A Slug Trap

Slug traps are best because they lure these creatures diverting them from their target.  Use beer or sugary liquid solutions, and once inside, the slugs will find it hard to navigate their way out.  This is a humane way to get rid of slugs in the house.  Empty your traps each time you catch a few slugs away from your house, so they don’t find their way back.  You can also make a beer trap by filling a container half full with beer and leaving it near where you dump them.
