Grubs in your lawn or garden? ✅ Effectively and sustainably combat grubs and beetles with GREEN GUARDIA HB Nematodes & Repellent Spray – completely chemical-free.

1. General information about grubs

Grubs are the larvae of beetles such as cockchafers, June beetles, garden chafers, and rose chafers . They live in the soil, are whitish, C-shaped, and several centimeters long. While they are harmless or even beneficial to some beetles (e.g., rose chafers), cockchafer and June beetle larvae cause considerable damage.

The grubs feed on the roots of lawns, flowers, shrubs, and vegetables . Large areas of lawns, in particular, can die when the larvae destroy the root system. Grubs are among the most feared pests in horticulture.

2. Detecting grub infestation – typical signs

A grub infestation in the garden or lawn is indicated by the following signs:

  • White, thick larvae in the soil (up to 5 cm long), C-shaped
  • Dying lawns that can be pulled off like carpet
  • Weak, stunted plants due to root damage
  • Secondary damage caused by animals : Birds, hedgehogs or moles burrow more frequently in the lawn to eat grubs

Anyone who notices these signs should act quickly, as grubs can destroy entire areas.

3. Preventing grubs – Tips for garden & lawn

How to prevent a grub infestation :
