The European chafer beetle problem isn’t going away anytime soon. We are seeing a lot of damaged lawns right now in the Tri-cities area where I live. So much damage, it even enters the conversation on soccer field sidelines. Many of the soccer parents are clearly frustrated with the damaged look of their lawns. Otherwise they would be discussing their sons’ performances on the pitch.
I don’t have any good news for you. It’s fall and if your lawn is damaged by birds and animals digging for grubs there is very little you can do. Once the grubs are eaten you should fix your damaged lawn. Simply rake out the damaged spots and install a light layer of turf blend soil. Then rake it into the lawn.
My City of Port Moody handout on chafer beetles suggests covering up the damaged lawn spots to deter further damage from animals.
November is a bit late for applying grass seed because there isn’t enough sunlight for grass seed to germinate. Wait for spring when daytime temperatures shoot up.
One thing you could do now is apply winter fertilizer to your lawn for strong roots. If your lawn wasn’t aerated in spring you could do that now before the ground gets really cold and stiff. Core aeration allows more oxygen and water to reach the root zone.
In spring 2018 you should start caring for your lawn or hire professionals to do it for you. Municipalities have their own handouts on chafer beetles so pick one up where you live and follow the steps. Aeration is a good idea again in spring.
I know it takes effort and costs money but fixing your damaged lawn areas will make you happier. Rake everything over and put down more turf blend soil. Rake it in and overseed once temperatures go up.
You can pre-order nematodes for late summer application in spring. I have a private client who applied them in 2016 but declined the service in 2017. As of right now, November 2017, his lawn is fine. Only his neighbour’s uncared for lawn has chafers.
This is an interesting case because the recommendation is to apply nematodes every year. I know, more bad news. But if you need help, I can come help you apply it the first time. Once you’re trained, you can do it yourself. Or just follow the directions; and check my previous blogs on chafer beetle battles. Read my previous blog on nematode application.
You can also consider alternatives. Yesterday I was blown away by a lawn in Port Coquitlam. The owners planted their front lawn in clover. Actual clover, not the micro version that’s mixed in with seed and sold as anti-chafer mix. For a hefty price, too.
Clover will attract bees and other insects and chafers don’t care for clover. I think when it’s nicely edged, it looks good. There are other ideas so spend the winter thinking about it. You can also read some of my previous blogs on lawn alternatives.
No action is required for your lawn in December. The way it’s been going, it will be covered by snow anyway. So just enjoy the holidays.
