Slugs, soft-bodied molluscs drawn to dark, damp hideaways such as vents and drains, can become a nuisance in homes and gardens, especially during winter when fading daylight limits opportunities to inspect plants. These predominantly nocturnal creatures often leave shimmering trails on floors and walls as evidence of their nighttime activity.
Outdoors, telltale signs of slug activity include gnawed holes in plant leaves and fruits, along with slimy trails revealing where they have emerged. Pest control specialist Edris Latifi, proprietor of Eco Care Pest Management, suggests the solution may already be in your kitchen cupboard.
Five Natural Remedies Recommended by a Pest Expert
Edris recommends trying common household ingredients before considering drastic measures such as professional pest control. One such remedy is coffee. Ground coffee can work wonders in protecting plants that slugs have developed a fondness for. Sprinkling it around plants has proven effective, and Edris advises simply leaving the coffee grounds to do their job. He notes that "the higher the caffeine concentration the more effective it will be".
Thanks to its notably slippery consistency, petroleum jelly can prove highly effective in preventing slugs from gaining purchase on surfaces and reaching plants, flowers, or household areas. Smear the balm around the rim of flower and plant pots, as well as along plant stalks, to stop slugs from gripping and gnawing through greenery. For problem areas indoors, apply a ring of Vaseline around drains and vents to trap slugs in their tracks.
Simple Barriers Using Household Waste
Eggshells are another household waste product that can be put to good use. According to Edris, these are "a great option as slugs don't like moving across jagged objects." Simply crush an empty eggshell into small fragments and scatter them around flowers and plants to protect them from slug damage. This technique can also benefit soil, as the calcium contained within the eggshells helps to enrich it as they break down.
Much like eggshells, crushed nutshells operate in precisely the same manner to repel slugs. Break the nutshells into small pieces and form a protective barrier around plants.
Seaweed as a Natural Deterrent
Less likely to be lurking in your cupboard, seaweed is nevertheless readily available in most supermarkets. Whether powdered or fresh, seaweed is remarkably effective at deterring slugs. Position the seaweed surrounding the plants and spots you wish to protect, and allow the elevated salt levels to do the work.
