If your lawn is only slightly damaged and you’re looking for an affordable, short-term fix, nematodes are a great option! These tiny creatures (Heterorhabditis bacteriophora) are natural predators of Chafer beetle grubs.


The best time to apply nematodes is between mid-to-late July, right when the Chafer beetles are laying their eggs. Timing is key because the nematodes can only target the younger, smaller grubs. If you apply them too late, the grubs will be too big for nematodes to feed on.


Here’s how to use them:


Pre-water your lawn: Water your grass for 2 hours before applying the nematodes. This will help them move through the soil.

Apply on a cloudy day: Try applying them on a cloudy day or in the late afternoon to avoid the harsh midday sun.

Water after application: After applying the nematodes, water your lawn again for 2 hours. Keep watering your lawn twice a week for the next three weeks.

Reapply annually: For long-lasting protection, apply nematodes at the same time every year to keep your garden safe.
