NemaControl Chafer Grub Control is a professional-grade biological solution for targeting chafer grub infestations in lawns, turf, and planting areas. This treatment uses beneficial nematodes (Heterorhabditis bacteriophora) that naturally seek out and destroy chafer grubs in the soil before they can cause significant root damage.
Safe, sustainable, and effective, NemaControl offers an excellent alternative to chemical insecticides—ideal for use in amenity turf, golf courses, public green spaces, sports fields, and domestic lawns.

Applications & Uses
Chafer grubs feed on the roots of grass and plants, causing thinning, browning, and dieback. Affected turf is also prone to being torn up by birds, badgers, and foxes seeking grubs.
Use NemaControl to treat:
Lawns and ornamental turf
Sports pitches and playing fields
Golf greens and fairways
Parks and public grounds
Garden borders and bedding plants
When and How to Apply
Apply when soil temperatures are above 12°C and grubs are present near the surface, typically between late May and early October.
Water the soil before and after application to ensure good penetration.
Avoid applying in full sun; early morning or evening is best.
Use a watering can with a coarse rose, hose-end sprayer, or nematode applicator.
