There’s no doubt about it: pests can be the bane of a gardener’s life. There’s nothing worse than growing the perfect crop of tomato plants, only to have them demolished by slugs and insects. Chemical pesticides can be highly effective at deterring and removing unwanted critters, however, these can be detrimental to the environment, and other beneficial wildlife. So here are some great eco-friendly pest control methods that can be equally effective.

Netting & Cloches

Pigeons, along with many species of insects, enjoy eating flowers and vegetable plants. Protective netting is a great way of keeping your plants safe and sound, however, there needs to be space between the net and the plant, otherwise, birds may land on the net and peck through it if they can. You can support your netting with bamboo canes or upturned pots, however, cloches and grow tunnels provide a ready-made safety system. This set of 3 Victorian Glass Bell Jar Cloches are a stylish way to protect growing plants.

Companion Planting

Companion planting involves growing your plants alongside other species that will disguise the vulnerable plants, or attract predatory insects that feed on pests. This is a great method of eco-friendly pest control, as it is harm-free, increases the biodiversity of your garden, and can also have other benefits such as improving taste and yields. Good companion plants for repelling unwanted insects include dill, fennel, allium, basil, coriander, and marigolds. Check out our full guide to companion planting here. 

Natural Sprays

Sprays have long been used to deter bugs from plants, however, there are plenty of eco-friendly natural alternatives to chemical pesticides. Spraying plants with water or a light soap solution can remove aphids, caterpillars, or similar insects from plants, and creating a herbal water spray from essential oils such as sage, thyme, basil, or rosemary can act as a repellent. You could also spray with a pepper or alcohol solution to deter pests.

Natural Predation 

Your garden can be a great place to support species of animal that are declining in the wild, and many of these creatures have the added benefit of ridding your garden of unwanted pests. Animals such as birds, hedgehogs, ladybirds, frogs, and lacewings are great at limiting numbers of common garden pests such as slugs and aphids. To encourage these critters into your garden, make them welcome by adding homes such as bird nest boxes, hedgehog houses, and ladybird towers. You can also add bird feeders, birdbaths, and leave out bowls of food and water for wild animals.

Organic Deterrents

Many organic substances are great for deterring unwanted pests, and are completely environmentally friendly! Many plant oils can be used as an insect deterrent, along with garlic- you can stick a clove next to your plants to drive unwanted pests away. Slugs do not like the sharp edges of eggshells, so surrounding plants with them can keep them safe from these pesky critters. Beer traps are also a common method of slug protection.

Ultrasonic Repellers

Ultrasonic repellers are a high-tech humane way of deterring a wide range of unwanted pests from your garden. These handy devices emit high-pitched noises that are beyond the range of human hearing but scare away other creatures. They can be used to keep larger creatures such as foxes, deer, and cats out of your garden, but can also be used in your house to deter pests such as spiders and mice. The Advanced Solar Mole Repeller emits low-frequency vibrations into the soil to deter moles from digging up your lawn, and the Advanced Rat and Mouse Repeller combine ultrasonic frequencies with electro-magnetic technology to keep your whole house free of rodents.
