June bugs do not bite. They lack the mouthparts to pierce or break human skin, and they don’t sting either. These clumsy, buzzing beetles are essentially harmless to people, even though their habit of crash-landing into you on a summer evening can feel startling.
Why June Bugs Can’t Bite
June bugs belong to the scarab beetle family, and their mouthparts are designed for chewing soft plant material, not for biting skin. Adult June bugs feed on leaves, flowers, and fruit. Their jaws simply aren’t strong or sharp enough to puncture human skin.
That said, if a June bug lands on you and clings with its legs, you might feel a prickly, pinching sensation. Their legs have small spines and curved claws at the tips, built for gripping bark and plant stems. When they latch onto bare skin, those tiny hooks can scratch or feel like a bite. It’s not a bite, and it won’t break the skin in any meaningful way, but it explains why some people suspect they’ve been bitten.
Which Beetles Are “June Bugs”?
The name “June bug” applies loosely to several species of scarab beetles across North America. The most common are beetles in the genus Phyllophaga, brown and stocky, which emerge in late spring. In the southern U.S., the green June beetle (Cotinis nitida) is also widespread. It’s larger, metallic green, and a noticeably louder flier. Both types are harmless to humans, and neither one bites or stings.
The Real Damage June Bugs Cause
While adult June bugs pose no threat to you, their larvae (white grubs) can be a genuine problem for your lawn. The grubs live underground and feed on turfgrass roots, sometimes for two to three years before maturing into adults. Kentucky bluegrass, perennial ryegrass, and creeping red fescue lawns are the most vulnerable. Tall fescue, zoysia, and bermudagrass hold up much better against grub feeding.
Green June beetle grubs cause lawn damage in a slightly different way. They feed on roots and thatch but also burrow through soil, displacing dirt and creating uneven patches. That burrowing actually causes more visible lawn damage than the root feeding itself.
A secondary problem: animals love to eat grubs. Skunks, raccoons, and wild turkeys will dig up sections of your lawn to get at them, peeling back poorly rooted turf and leaving depressions behind. If you’re seeing torn-up patches of grass in late summer or fall, grub-hunting wildlife is a likely culprit.
Are June Bugs Safe Around Pets?
Dogs and cats frequently snap up June bugs, and in general this is safe. June bugs are not toxic. As long as the beetles haven’t been exposed to pesticides, eating a few won’t cause harm. Eating large quantities of any insect can lead to mild stomach upset, vomiting, or diarrhea, but that’s a volume issue rather than a toxicity issue.
Keeping June Bugs Away From Your Home
June bugs are strongly attracted to light, which is why they swarm porch lights and bump against windows at night. The simplest way to reduce the swarm is to minimize the light you broadcast after dark. Close blinds, turn off unnecessary outdoor lights, or switch your porch bulb to one that emits light in the yellow-red spectrum. Many insects have difficulty seeing those wavelengths, so yellow “bug lights” dramatically cut down on the crowd at your front door.
For longer-term control, treating your lawn for white grubs reduces the local June bug population before they ever reach adulthood. A healthy, well-maintained lawn with grub management means fewer adult beetles showing up the following spring. Since May and June beetles can take two to three years to complete their life cycle underground, consistent lawn care over multiple seasons makes the biggest difference.
