About Nemasys Chafer Grub Killer (500 m²)

What is it?

Nemasys Chafer Grub Killer is a biological pest control containing Heterorhabditis bacteriophora, a species of nematode (microscopic worm) that infects chafer grubs naturally. Nematodes are a chemical-free option that’s commonly used in horticulture for pest control.

How does it work?

Fair warning: this bit isn’t for the squeamish. Juvenile nematodes enter chafer grub larvae through their natural body openings. Once inside, they release bacteria that stop the grub feeding and kill it quickly. The nematodes then grow into adults and breed inside the grub for two or three generations, until the food supply starts to run low and thousands of new juveniles disperse into the soil to find more grubs.

How effective is it?

Used correctly, this kind of biological pest control can be effective. Applied properly, nematodes can reduce chafer grub populations in the treated area in subsequent years.

Use Nemasys Chafer Grub Killer within 3-4 weeks of receiving it. Keep it refrigerated until you use it.
