Slugs are garden pests that can cause major damage to your plants. Homemade sprays for controlling slugs offer a natural and non-toxic alternative to chemical-based pesticides. Many commercial slug control products contain harmful chemicals that can not only harm slugs but also have detrimental effects on other beneficial insects and wildlife. Natural slug repellents are not only effective but also environmentally friendly alternatives to chemical pesticides.
Top 10 Homemade Sprays for Slugs
Diatomaceous Earth
Diatomaceous Earth is an eco-friendly slug solution in your garden. When slugs come into contact with the diatomaceous earth, they dehydrate their bodies by absorbing the moisture from their skin. This causes them to die eventually. Unlike chemical pesticides, DE is non-toxic to pets, making it a safe option for slug control. To use diatomaceous earth as a slug deterrent, sprinkle a thin layer around the plant base or create a perimeter around your entire garden. Make sure to reapply after rain or watering to maintain its effectiveness.
Copper Tape Barrier
Slugs are known to dislike copper, making this a natural and non-toxic pest control for slugs. To create a copper tape barrier, wrap the adhesive-backed copper tape around the base of pots or planters or create a perimeter around your garden beds. The slimy pests will be deterred by the electrical charge that occurs when they come into contact with the metal. The great thing about using a copper tape barrier is that it can be easily applied and removed as needed. It adds an attractive touch to your garden decor. Just make sure to clean any debris or dirt off the surface before applying the tape for optimal effectiveness.
Citrus Peel Spray
This homemade remedy harnesses the power of citrus fruits like oranges, lemons, and grapefruits to create an effective slug deterrent. To make your citrus peel spray, collect leftover peels from your morning juice or snacks. Place the peels in a jar and cover them with boiling water. Let the citrus peel mixture steep overnight before straining out the liquid. Once you have your citrus-infused concoction ready, transfer it into a spray bottle. Then generously spritz it onto areas where slugs tend to congregate – around plant bases or along garden borders – creating a barrier that will keep those pesky pests at bay.
Coffee Grounds Barrier
The strong scent of coffee can repel these slimy creatures and keep them away from your plants. To create the coffee grounds barrier, sprinkle a generous amount around the base of the plants you want to protect. Make sure to spread it evenly so that there are no gaps for slugs to crawl through.

Not only does this method help ward off slugs, but it also acts as a natural fertilizer for your soil. Coffee grounds are rich in nitrogen levels, which can promote healthy plant growth. Remember to replenish the coffee grounds regularly, especially after rainfall or watering. This will ensure that their odor remains strong enough to repel any lurking slugs.
Breer Trap
The Breer Trap is a simple yet effective solution for getting rid of slugs in your garden. To create a Breer Trap, start by burying a container up to its rim in the ground. This could be an old plastic cup or even a yogurt container. Fill the bottom of the container with beer, which acts as bait for the slugs.
Slugs are attracted to the yeast smell in beer and will crawl into the pot, seeking it out. Once inside, they become intoxicated by the alcohol and are unable to find their way back out. In effect, this DIY slug trap becomes their final destination. Remember to check your Breer Trap regularly and empty it as needed. Refill with fresh beer to continue attracting more slugs.
Epsom Salt Spray
Epsom salt is not only beneficial for your body but can also be an effective solution in controlling slugs in your garden. This simple and affordable homemade spray works by dehydrating the slugs and ultimately driving them away. To make an Epsom salt spray, dissolve Epsom salt in about one cup into a gallon of warm water. Once dissolved, transfer the mixture to a spray bottle and apply it to areas where you’ve observed slug activity.
The high magnesium content in Epsom salt acts as a desiccant, drying out the slugs and causing them to shrivel up. It’s important to note that this method may harm other wildlife or plants if overused or applied directly to them. By using this natural remedy, you can create an unfavorable environment for slugs without resorting to harmful chemicals. However, it’s essential to regularly reapply the Epsom salt spray after rainfall or heavy watering since it easily washes away.
Garlic and Onion Sprays
Garlic and onion sprays are not just great for adding flavor to your favorite dishes, but they can also be effective in deterring slugs from wreaking havoc on your garden. These pungent vegetables contain compounds that repel slugs, making them natural for controlling slug infestations. To make a garlic spray, blend several cloves of garlic with water until you have a concentrated liquid.
Strain the garlic mixture and transfer it into a spray bottle. Spray the solution directly onto plants or around the garden perimeter to create a barrier that slugs will want to avoid. Onion sprays can be made similarly by blending onions with water and straining the mixture before transferring it to a spray bottle. Like garlic, onions emit an odor that is unpleasant for slugs, which helps keep them away from your precious plants.
Vinegar Spray
To make this DIY vinegar spray, all you need is white vinegar and water. Mix vinegar and water equally in a spray bottle, then generously spritz it onto the leaves and stems of affected plants. The strong odor and taste of vinegar act as a deterrent to slugs, preventing them from feasting on your precious greens. And unlike chemical pesticides, vinegar spray won’t harm beneficial insects or contaminate your soil. Remember to reapply the vinegar spray after rain or watering to ensure its effectiveness.

Lavender Oil Spray
Lavender oil spray is not only a delightful scent for humans, but it can also serve as an effective homemade slug barrier. These slimy creatures are repelled by the strong aroma of lavender, making this natural homemade spray a great solution to keep them at bay. To make your lavender oil spray, mix pure lavender oil with water in a bottle.
Shake well before use and then generously spritz the mixture around areas where slugs tend to congregate or where you’ve noticed signs of their presence. The powerful scent of lavender will act as a barrier and discourage slugs from venturing into your beloved plants. Plus, it’s completely safe for both humans and pets, so you don’t have to worry about any harmful chemicals being introduced into your garden environment.
Salt Solution
To make a salt solution, dissolve a generous amount of table salt in water until it forms a concentrated mixture. Then, transfer the salt solution into a spray bottle for easy application. When using the salt spray, aim directly at any slugs you spot in your garden. The high concentration of salt will cause dehydration and ultimately kill these slimy pests.
It’s important to note that while this method is effective, it should be used with caution as excessive use can harm other plants and soil organisms due to its high salinity levels. Therefore, only target specific areas where slugs are present rather than applying them indiscriminately throughout your entire garden. Remember that prevention is important when dealing with slugs.
