Why Do Slugs Come into My House and How To Get Rid of Them?

How To Get Rid Of Slugs In Your House

Imagine stepping on a slug while walking to your room with bare feet. Pretty disgusting, right? The same slugs can keep coming back to your house if you don’t find ways to throw them out.

Slugs leave behind their very own scent trail, which allows them to find their way back to your home.

Slugs mostly eat mould, leftovers, algae, and compost. They are attracted to cold, damp, dark refuge areas like drains, vents, and kitchens.

Slugs are more prevalent in old houses as they are damp and cold. If your house is full of moisture and dampness, slumps are more likely to enter your house. Cold and damp places attract slugs, which is why you should take effective measures to prevent it.

Another reason can be pet food. If your house is full of pet food scents, slugs may often make their way into your house. They are more likely to come on rainy nights as their sense of smell maximizes on these days.

Plants or herb pots can also be the reason for regular visits by the slugs.

One way to prevent drugs from entering is to make sure there are no cracks or gaps on your front door and windows.

Slugs come to your house because they usually need something, be it shade, food, or warmth. You should find out what attracts them to your house in order to keep them out.

Here’s a fantastic video that provides some useful tips and tricks on how to get rid of slugs:

How Do Slugs Get In?

Slugs OutsideSlugs can smell pet food and leftovers. They don’t have hard shells like other insects do, which helps them squeeze through tiny cracks.

Slugs can stretch their body up to 20x times than their normal structure. They have no bones or skeletal structure, which causes them to enter through the smallest gaps in your door.

They can walk upside down and climb on vertical surfaces. They have some commonly preferred entry points like ill-fitted doors, spaces under windows, holes drilled in your floors for gas pipes or water, joints along the surface of your walls, holes associated with electrical wiring, cutouts for dryer ducts or furnaces, and others.

How to Stop Slugs From Entering Your Home

Here are some quick tips on how to locate and eliminate the hiding spots of slugs to prevent them from coming back to your house.

Slug Bait

Place pellets where the slugs are more likely to hide. Control the repeated entry to your house by killing them at once with pellets.

These slug baits are not toxic to pets and children of your house, so there is no risk of accidental consumption.

They appear tasty to slugs and are effective in killing them. The last few years have seen improvements in the manufacturing of slug baits. They are developed using iron phosphate, which is toxic only to snails and slugs.

If slugs eat this bait, they will stop feeding and die after a few days. Refrain from using slug baits containing metaldehyde as it is toxic to pets and people.

Read through the specifications before buying a slug bait, as metaldehyde baits have an animal repellent coating. Go for slug baits labelled as safe for pets. You do not want your cat or dog or rabbit feeding on them when you are not looking and fall fatally sick.

You should always opt for the newer variants in slug pellets or baits. The old-style slug baits, apart from being toxic, are also slow in killing the slugs. The new pellets will act on the slugs from the very first time and kill them quickly.

Door Seals

Most doors have a substantial gap between them and the floors. Slugs mostly come in through such gaps as they have no bones in their body.

Door seals are the ideal way to close all entry points of slugs into your home. There are many options for door seals – they are discussed later in this article.

You need to slide the door seals under your door to eliminate the gap between them. If you have a carpeted floor, use a few duct tapes to slide easily under your door.

You can trim the door seals as per your needs and seal all existing gaps between the floor and doors.

Diatomaceous Earth

The fossilized remains of diatom, photosynthetic, single-celled aquatic algae, can also be used to eliminate slugs from your home.

The remains of millions of diatoms over the ages to form the soft, crumbly sedimentary rock called diatomaceous earth. You can sprinkle it on slugs directly or use it at the entry points as a barrier.

If your surrounding environment is dry, diatomaceous earth can effectively kill slugs and other insects. However, it is not effective in wet places. You need to apply them in places where there is no moisture. If you have a damp house, you should directly sprinkle it over the slugs.

Diatomaceous earth contains silica, which is toxic to the digestive system of the slugs.


Salt is an effective barrier to prevent the entry of slugs into your house. However, you should try to place them in an area where it is dry.

They will wash off quickly if you put them in a wet or damp place, as it is the property of any salt to dissolve in water.

If you leave a salt path in your house, it will cause the slugs to dry out along the path and eventually die. You can also sprinkle some salt near your door before going to sleep to prevent the entry of slugs at night.

Crushed Eggshells

Many people suggest crushed eggshells as an alternative for driving away slugs from your house.

However, it is not quite as effective as some of the other remedies on this list.

Create A “Beer” Trap

Some people prefer using beer as a home remedy to kill slugs. The yeasty odour of beer attracts slugs and draws them towards their death.

Slugs may crawl into beer containers and drown in them after failing to find an escape. You can create a beer trap for eliminating slugs from your house.

Find a plastic container with a lid to set up your trap. Margarine tubs or yoghurt containers will be great for this purpose. You should make a few holes on the top of the container to provide access to the slugs.

Bury the beer container in your garden or outside the house by keeping about an inch above the soil. Pour beer into the container and close the lid.

You should regularly check the beer traps to measure its effectiveness.  You should also remove all dead slugs and pour more beer regularly.

Birds, Ducks, And Other Predators

You can build a bird table to attract birds. Birds are predatory towards slugs and will eat them for you. You can also keep pet ducks in your garden for the same purpose.

However, this option is obviously not attainable or affordable for most.

How To Seal Cracks And Stop The Entry Points?

Use PU Foam ForLarge Gaps

If your house is full of larger gaps, you should opt for polyurethane foam cans. Polyurethane foam can expand and fill up all such gaps and cracks in your household.

It creates a waterproof and pest-proof barrier with incredible durability. You should spray it around joints, ducting, and spaces between doors, and anywhere else the slugs can make way through.

Wear old clothes and gloves while spraying expanding PU foam as it will stick to everything nearby when you spray.

After the foam seals and hardens, you can trim off any excess foam using a hack saw blade or serrated knife. Be careful enough to locate all gaps in your house.

Use Sealants For Small Holes

If you have tiny gaps in between your floors or doors, silicone sealant will work better than expanding foam.

You can squeeze out the product and seal of all the suspicious holes in your house. Cover spaces around your door trims, floors, walls, and joints. If you need to work with tight spaces, opt for squeeze tube sealants.

Copper Tapes To Keep Slugs Away

Copper tapes are the easiest solution to eliminate all slugs from your house. However, they are less effective than expanding foams and sealants.

Copper tapes last long, offering greater value for money. You can place them across your floors, door thresholds, and around pots.

Copper is known to react with the slime of a slug, thus disturbing its nervous system. The slugs will feel a reaction equal to an electric shock, causing them to die slowly.

However, in most cases, snails and slugs slide past them without much effort. You should opt for a copper tape with high ratings and good reviews. If you need something more full-proof, then opt for sealants and PU foam.
