Product Overview

Koppert Terranem is specially designed to help control beetles (grubs) effectively. It contains Heterorhabditis bacteriophora, a type of entomopathogenic nematode (EPN), Thread Worms, which specifically targets larvae of different species of beetles (grubs), particularly garden chafers (Phyllopertha horticola). It's also deemed effective against dung beetles from the genus Aphodius and Serica brunnea, Hoplia spp. It works when the nematodes look for grubs to penetrate them. It feeds on its content, but also excretes specific bacteria from their digestive tracts at the same time. The host tissue will be converted into products by these bacteria, making it easier for nematodes to ingest. The grubs will turn from white-beige to red-brown in color, become slimy and may die within a few days after application.

Koppert Terranem is available in two sizes:

  • The small pack comes in a box with a bag that contains 50 million Heterorhabditis bacteriophora larvae (worms).
  • The large pack comes in a box with 2 bags that contain 500 million Heterorhabditis bacteriophora larvae (worms), 250 million per bag.
