Gardeners facing slug and snail infestations can turn to common kitchen scraps for a natural solution. Eggshells, when crushed and scattered around plants, create a sharp barrier that slugs avoid. Some gardeners even use half eggshells to form a more substantial obstacle. However, the Royal Horticultural Society (RHS) warns that heavy rain can make eggshells slippery and less effective.
Citrus and Beer Traps
The RHS also recommends traps made from scooped-out orange, grapefruit, or melon skins placed cut-side down, or jars partially filled with beer sunk into the soil near vulnerable plants. These traps should be checked and emptied daily, preferably each morning, to draw molluscs away from crops like salad leaves, courgettes, peas, and strawberries.
Biological Control Option
For those seeking a biological method, 'Nemaslug' offers an organic solution. This product contains microscopic nematodes that are watered into the soil. The nematodes infect slugs with a fatal bacteria, posing no risk to other wildlife. According to the RHS, this method is safe and effective for controlling slug populations without harming birds or other garden creatures.
While slugs play a role in the ecosystem as a food source, they can quickly overrun gardens. Avoiding chemical slug pellets, even organic ones, protects beneficial wildlife. Natural and biological controls provide effective alternatives for keeping vegetables and strawberries safe from slug damage.
