Combating grubs biologically with insect-parasitic nematodes

Grubs are the larvae of a beetle that is part of the scarab beetle family. Grubs can cause considerable damage to grass and plants by feeding on the root hairs. This makes it harder for the grass/plants to absorb water and nutrients. Other creatures such as moles and birds can increase the damage by searching for the grubs in the soil.

It is possible to combat grubs biologically using nematodes. Using nematodes we offer a solution for controlling grubs to sectors such as tree nurseries, public green spaces, and sports fields, where these pests can cause damaging infestations.

The best known grub is the larva of the May bug (Melolontha melolontha). The larvae of the June beetle (Amphimallon solstitialis) and the garden chafer (Phyllopertha horticola), among others, are also called grubs.

How Terranem works
Terranem contains the nematode Heterorhabditis bacteriophora. After application the nematodes go in search of the grubs of the June beetle and garden chafer and enter them through naturally occurring body openings. Infected grubs change colour from whitish-beige to reddish-brown and the insect becomes slimy, often making it difficult to find.
