The Koppert Larvanem 50 Million (74520) holds Heterorhabditis bacteriophora (third stage larvae) in inert carrier material. It targets the larvae of different species of beetle, such as as the black vine weevil Otiorhynchus sulcatus. Nematodes work by earnestly searching for the target species and penetrating them. They feed on the contents of the larvae by discharging specific bacteria from their digestive tracts. These bacteria change host tissue into materials that nematodes can easily ingest. Affected specie will become slimy and its color will turn from white-beige to red-brown. Within a few days, all larvae are expected to die.
Koppert Larvanem is available in two sizes:
- The small size contains 50 million larvae.
- The large size contains 500 million larvae.
IMPORTANT: These are live organisms that are shipped directly from the manufacturer via UPS Next Day Air so they do not die during transit. A physical address is required for UPS to deliver your package. These are only shipped twice a week:
- Orders received by noon (12pm ET) on Monday will be shipped on Thursday for Friday delivery
