June Beetle Control: How To Get Rid of June Bugs

While in the south there are several different beetles that are referred to as a June Bug, the true June bug is the June Beetle, which is a metallic green colored insect that often has yellow stripes on their wings. The June Beetle is a very common pest to gardeners and lawn owners because of the damage they do to plant life. If left untreated, June Beetles can multiply and ruin a garden because of their frantic eating, mating, and egg-laying habits.

June Beetles do most of their damage as larvae to ripe fruits, tomatoes, figs, berries, apples, peaches, plums, and even corn. This makes them a particularly troublesome problem in orchards. When there isn't fruit available, they would happily eat grass and garden plants.

June beetle damage to turf can be so severe if their populations are high that the turfgrass can be rolled away from the ground similar to the way one would roll up a carpet or rug. If you have June Bugs plaguing your yard, Solutions Pest and Lawn has the products to take them out and keep them away.

By following our professional DIY guide, you can get rid of a June Beetle infestation yourself. Use the recommended products on the side and follow our step-by-step directions below to eliminate a June Beetle problem quickly and affordably.

Identification

Before you can carry out a treatment program, you need to determine what June bugs look like so you know for sure that is the pest you are encountering. Misidentification can lead to using the wrong treatment methods, costing you time and money.

• June beetles refer to a type of beetle from the Phyllophaga genus, of which there are 300 different species. They get their common name because of the times of the year where they are seen the most. Adult beetles are 0.5 inches to 1 inch long.
• The upper body of the June Beetle can be velvety green to a dull-colored brown. The underside of the body is shiny metallic green or gold. June Beetles have elytra, a hardened shell-like forewing that opens and closes when they take flight. Adults also have a distinct, small, flat horn on the head. The larvae stage of June Beetles are white and c-shaped grubs about an inch in length.
• Adult June Beetles emerge spring through summer, laying eggs under the soil that will hatch into grubs 3 to 4 weeks later. The grubs will feed on grass roots until they grow into adults and emerge in the late spring and summer.

Inspection

Once you have confirmation you are dealing with June Bugs, proceed with an inspection to locate their hotspots of activity so you know where to focus your treatment applications.

Where to Inspect

Perform a careful inspection on your lawn to see where these June Beetles are residing and whether you have a small or large infestation in your garden. Check the damage of your garden plants and if there are any eggs in high grass or weeds. Look in areas where you see patches of dying grass especially.

Since June Bugs are found under the soil you will have to dig a 1 foot square patch 3 inches deep and check for any pest activity.

What to Look For

You should be looking for active adult June Beetles or evidence of June Beetle activity. When you cannot locate any June Beetles, check for grass damage that they may have inflicted.

Timing is important when treating for June Beetles as these bugs are known to lay a lot of eggs and it would be best to control them before they hatch and add to the damage. Adult June Beetles are attracted to light so you may see some clustered around your outdoor lighting and windows.

Treatment

Once you have completed the inspection, you should then prep your lawn for chemical treatment. Before applying chemicals, we recommend wearing personal protective equipment for safety.

The product we recommend to treat for June Bug larvae is Dominion 2L. Apply the insecticide preferably around June or July.

If you observe June Beetles depositing eggs in the soil, you can gauge the timing of insecticide application. June beetle grubs emerge from their eggs about 3 weeks after eggs are deposited into the soil around shrubs and in lawns.

Step 1 - Apply Dominion 2L to the Lawn

Dominion 2L is a systemic insecticide that can be used to control larvae underneath dirt and treat the adults along the entry points of your home.

Start by first calculating the square feet of your lawn or treatment area. Do this by measuring your lawn's length and width in feet, and then multiplying them together (length x width = square footage). This will determine how much Dominion 2L you will need to mix.

Dominion 2L should be broadcast, preferably with a hose-end sprayer, at a rate of 0.46 to 0.6 fl. oz. per 1,000 sq. ft.

Make sure the sprayers control valve and water pump are off and then attach the hose-end sprayer nozzle to the hose. Remove the reservoir from the nozzle and then add the proper amount of Dominion 2L and the proper amount of water. Plan to use 2 gallons of water per 1,000 sq. ft. of treatment area.

Attach the reservoir back to the nozzle and turn the water on and begin broadcasting evenly over your lawn by pushing forward on the control valve. As you make the application, make sure to keep track of the amount of product you have left in the reservoir.

Step 2 - Apply Dominion 2L Around Your Home Perimeter

Next, you should spray a perimeter treatment of Dominion 2L around the outside of your home and structure to create a barrier that will keep June Beetles out. Use a hand pump sprayer for precise spot applications.

To use a pump sprayer, open the sprayer and add half a gallon of water followed by the appropriate amount of Dominion 2L, then fill with the remaining half-gallon of water. Agitate the sprayer until well mixed and you are ready to apply.

Spray around doors and windows, around the foundation going up 2 or 3 feet then spray any other possible points of entry. You should also treat around exterior lighting since June Bugs are attracted to these areas.

Prevention

After eliminating the June beetle infestation, you will need to work to prevent the infestation from returning. In the summertime, June Beetles will be waiting to feast on your garden. 

• Regular monitoring and a consistent lawn maintenance schedule is the best preventative practice to put into place to make sure June Beetles don't make a comeback to damage your garden or lawn. Rake your lawn regularly to remove thatch and expose the June Beetle grubs to its natural predators.
• Water your grass with 1 to 1.5 inches of water once a week and mow your grass at a height of 3 to 4 inches to encourage root growth. June Beetles like to lay eggs in short grass so try to keep your grass a little longer during the active summer season. You should fertilize on a regular schedule to make sure your turf gets the nitrogen nutrition it needs to fight against pest symptoms.
• Finally, make preventative applications of Dominion 2L every 3 months to keep June Bugs off of your yard.
