Grub worms are commonly referred to as June bugs or May beetles and are a type of scarab beetle that eats at the roots of plants, grasses and vegetables. Both the larvae and adults of the species can become problematic for gardeners and can wreak havoc on lawns and landscaping.
The adults emerge beginning in spring and are attracted to light. The female grub worm will tunnel into the soil to deposit her eggs. Patches of brown on the lawn that you can peel away in sections, like carpet, are indicative of a grub worm infestation. There are several treatments for grub worms, including pesticides like Neem oil that can be sprayed on to the lawn to kill them.
