How to Get Rid of June Beetles (Natural & Organic Methods)

By Sabrina Wilson / July 27, 2022

The furry brown or black June beetle is one-half to three-quarters of an inch long. The six-spotted green June beetle is about the same size. The adult does not do much damage to plants. It is the white C-shaped larva, or grub, that feeds on the roots of plants, especially grasses. Grubs are present in the soil from late spring to early fall. They are most numerous in early summer.

The injury done to turf grasses by grubs is often first noticed in early to mid-summer when the grass withers and dies in small, irregular patches. The turf can be pulled back easily to reveal the grubs feeding on the grass roots. In late summer and early fall, as the grubs mature, they move closer to the soil surface in preparation for winter. At this time, they may be found just below the thatch layer or in the top 2 to 3 inches of soil.

There are several ways to reduce grub populations and the damage they cause. One is to maintain a thick, healthy turf through proper fertilization, mowing, and irrigation. A well-cared-for lawn is more tolerant of grub damage and can better withstand an attack. Be sure to follow recommended cultural practices for your turf type.

In small areas, grubs can be killed by applying insecticides to the soil. Treatments should be done in late summer or early fall, before the grubs move deep into the soil for winter. Consult your local cooperative extension office or garden center for specific product recommendations and application rates.

Organic methods for getting rid of june beetles are preferable for a number of reasons. First, they are more environmentally friendly than using pesticides or other chemical methods. Second, they are often more effective at getting rid of the beetles than chemical methods. Third, they pose less of a risk to human health and the environment. Finally, organic methods are generally more affordable than chemical methods.

Beneficial Nematodes

There are a few different species of June beetles, also called June bugs, but the most common in North America is the Northern Rose Chafer. These reddish-brown bugs are about ½-inch long as adults and are attracted to lights at night. The larvae, called white grubs, are plump, C-shaped worms that live in the soil and feed on the roots of grasses and other plants.

If you have June beetles in your yard, you can get rid of them using beneficial nematodes. Beneficial nematodes are microscopic worms that kill pests by entering their bodies and releasing bacteria that dissolve the insides. They’re safe to use around people and pets and won’t harm beneficial insects like bees and butterflies.

To use beneficial nematodes to get rid of June beetles, mix the nematodes with water according to the package directions and pour them into a garden hose-end sprayer. Then, water the entire yard, paying special attention to any areas where you’ve seen the beetles or their larvae. Reapply every 4 weeks through the summer to keep June beetles away.

Neem Oil

To get rid of june beetles, mix equal parts neem oil and water in a spray bottle and shake well. Spray the mixture on the beetles and their larvae, and also on the leaves of any plants that are infested. Repeat every few days until the beetles are gone.

Insecticidal Soap

Insecticidal soap is a mixture of fatty acids and potassium hydroxide. The fatty acids work by breaking down the cell membranes of insects, while the potassium hydroxide disrupts the ion balance within the cells, causing the cells to collapse.

If you have a june beetle problem, insecticidal soap is a good solution. Mix up a batch of soap following the directions on the package, and then apply it to the affected area. The june beetles will be killed on contact, and their bodies will be easy to clean up.

Horticultural Oil

Modern insecticidal soaps are highly effective against a wide range of common pests, including aphids, whiteflies, spider mites, and thrips. Insecticidal soap works by disrupting the surface of an insect's exoskeleton, which leads to dehydration and death. Insecticidal soap is made of potassium salts of fatty acids, which act as a surfactant. This soap-like material is then mixed with water and applied to plants.

Horticultural oil is a great way to get rid of June beetles. You can either purchase horticultural oil at your local nursery or make your own. To make your own horticultural oil, mix 1 part canola oil with 1 part dish soap. Mix well and apply to the affected area. Apply the horticultural oil in the evening so that the June beetles will be attracted to the light. Be sure to apply the horticultural oil to the tops and bottoms of the leaves so that the June beetles are getting the full treatment.
