European Chafer Grub
To most people, a grub is a grub. If you’ve seen one, you’ve seen them all. In the state of Michigan, there are two varieties of grubs that we most commonly see: the Japanese beetle and European chafer. The European chafer may be the most serious grub pest of home lawns. Although not as wide spread as the Japanese beetle, the European chafer is more damaging to your turf in areas where both are found. Unlike the Japanese beetle, the European chafer is not a problem in daily irrigated turf.
The European chafer grub is slightly larger than the Japanese beetle grub. It feeds later into the fall and starts feeding again earlier in the spring. They have even been known to resume feeding in the winter months during warm spells. Turf damage caused by grubs is most severe in drought conditions, when water stressed plants cannot grow new roots to replace injured one. Damage is observed when turf fails to turn green in early spring. Major infestation areas may turn brown and die during prolonged periods of dry weather in the fall or spring.
Here are some helpful hints to combat your European chafer problems:
- Keep your turf moist from the last week of June into the early part of August. European chafer won’t lay their eggs in moist soil.
- Over seed your turf, with a Tall Fescue blend of grass. It is more drought tolerant and has deeper root growth.
- Increase mowing heights when grubs are laying their eggs in the early part of July.
- Fertilize regularly to help promote a dense and healthy turf stand.
