How to Control Green June Beetles
There are several different beetles which are referred to as “June bugs;” but green June beetles are the giant, greenish, iridescent ones that are nearly an inch long.
June beetles lay their eggs in rich, sandy soil; and the adults often emerge after a hard rain to feed on fruit.
As I looked from my garden over the adjoining pasture, I could see thousands of beetles flying low over the grass, looking for mates and good places to lay next year’s eggs.
Adult green June beetles do most of their damage to ripe fruits – tomatoes, figs, berries, apples, peaches, plums, and even corn.
A few June bugs flying around your yard are usually nothing to worry about, but they can be particularly problematic in orchards, where their feeding and waste can ruin a good fruit harvest.
For egg-laying and grub activity, June beetles are drawn to rich soil; and they can become a pest of lawns, golf courses, and playing fields.
June beetle larvae fall in the general category of “white grubs.” They’re distinctive not only because they’re huge (up to 2” long), but because June beetle larvae crawl on their backs with their feet in the air.
If your lawn has a white grub problem, you may find June beetle grubs among them, but they’re likely to be far outnumbered by other, more damaging grubs such as Japanese beetles.
The larvae eat decaying organic matter, rather than plant roots, so their damage is mostly caused by tunneling and disturbing the soil under the grass.
If you only have a few beetles, the grubs can actually act as beneficial aerators of the soil. But if the infestation is severe, tunneling by white grubs can begin to cut off contact between the soil and grassroots.
Like other white grubs, June beetle larvae are active in the fall and spring, while adults are active in mid to late summer.
How to Control Beetles and Grubs
To check for green June beetle grubs, dig up flat sections of sod several inches deep. If you see upward of 10 grubs per square foot, your lawn may be suffering.
The best time to control adult beetles is in the summer when they’re most active. Beetle grubs should be tackled during the early fall.
Here are some tips on how to control beetles in your lawn or garden:
- Chemical Control: If necessary, there are chemicals available that are applied in the fall to control green June beetle grubs. Also, during the adult flying season, pesticide soaked overripe fruit can be placed around the perimeter of orchards to help control adult beetles.
