Heterorhabiditis Bacteriophora Nematodes

Beneficial nematodes are microscopic worms that attack and kill targeted insects, without affecting any other organisms. Within the infected insect, the beneficial nematodes continually reproduce and then spread out for long term control.

Target Pests: Larval and white grub stages of: European chafers (Rhizotrogus majalis), Oriental beetles (Exomala orentalis) and Japanese beetles (Popillia japonica)

Use in Biological Control: Nemasys G contains live nematodes (heterorhabditis bacteriophora) in their vigorously infective juvenile stage. These nematodes attack pest larvae by entering their natural body openings. Once inside, they release symbiotic bacteria that quickly kill the insect larvae. Reproduction inside the larvae releases a new generation of hungry, infective juveniles that disperse in search of further prey.

NOTE: Nemasys G (L and Millenium) is a special order item. We do not stock them. They are produced in England. The nematode orders are shipped from England to the US two times per month. We try and get them delivered as soon as possible, but there will be a delay between ordering and receiving them. With this method, you will be receiving the freshest nematodes available. Please contact us at support@buildasoil.com and we can furnish you with the ETA when you are ordering.

 Notice: The $225.00 price IS the price of two trays together.
