Introduce natural enemies to your garden, such as birds and hedgehogs, which like to eat grubs. Create a wildlife-friendly garden with plenty of hiding places to attract these beneficial animals.

Keep your garden clean and free of plant debris, where grubs can hide and feed. Regular weeding and removing dead plants will help make the area less attractive to these pests.

Rotating the crops in your garden each year can help reduce the chances of grub infestations. Grubs often lay their eggs near the same plants. By changing their locations, you disrupt their life cycle and reduce the chances of serious infestations.

One of the most effective and environmentally friendly ways to control grubs is to use biological nematodes against grubs . These microscopic worms penetrate the grub larvae and infect them with bacteria, which leads to their death. Nematodes are safe for plants, pets and people, and are a sustainable solution for your garden.
How to apply Nematodes?
