As soon as your lawn starts to green up in the spring, it’s time to start thinking about grub control. Grubs are the larvae of beetles, and if left unchecked, they can do serious damage to your lawn. The best way to protect your lawn from grubs is to prevent them from getting established in the first place.
There are two main types of grub control products on the market: those that kill adult beetles before they lay their eggs, and those that kill grubs after they hatch. Both have their pros and cons. Insecticide sprays that target adults can be effective at preventing an infestation, but they need to be applied regularly (usually every 2-3 weeks) throughout the summer to be effective. And since many of these insecticides are also harmful to bees and other pollinators, it’s important to use them only when necessary and follow all label instructions carefully.
Granular insecticides that target grubs are also available, but they need to be applied before eggs hatch in late summer or early fall. These products work by killing grubs as they feed on grass roots. They’re most effective when applied before egg hatch, so timing is critical for this type of product.
No matter which type of product you choose, always read the label carefully and follow all directions for safe and effective use.
