Japanese Beetles


Many backyard events can be spoiled by the presence of Japanese Beetles. Using a product such as Safer® Brand Japanese Beetle Trap will keep your backyard festivities free of these bothersome pests.


Japanese beetle traps such as the Safer® Brand Japanese Beetle Trap should be placed outside at the first spotting of a Japanese beetle. Read more about these annoying insects and how to control them.





So... What's a Japanese Beetle?

Japanese Beetles are voracious leaf-feeders and cause damage to a large variety of plants in a homeowner's lawn, landscape and garden.


Adult Japanese Beetles measure about 1/2" in length and have shiny bluish green bodies that appear metallic in the sunlight.  The copper or bronze colored wings add to this metallic appearance.


The larvae, often referred to as grubs or white grubs, measure about 3/4" in length and go through several instar or mini-stages. Eliminating Japanese Beetles begins with controlling the larvae. Using a product such as Safer® Brand Grub Killer will eliminate the larvae that causes Japanese Beetles.





Reproduction Patterns of Japanese Beetles


The white grubs or Japanese Beetle grublarvae overwinter down in the ground, and then in the spring, move upward toward plant roots to feed. After developing into a pupal stage at the beginning of summer, the pupae emerges as an adult and begins to feed on the plants around it.


The adults mate and the female deposits eggs in the soil during the middle to latter part of summer. After the eggs hatch, the larvae will dig into the soil to spend the winter. This life cycle may take a year or two. Be sure you do not have this life cycle happening in your yard by using a product such as Safer® Brand Grub Killer to eliminate the Japanese Beetles at the larval stage.





Japanese Beetle's Habitat

First found in the United States in 1916, this insect has spread to almost all areas east of the Mississippi River. Smaller pockets of infestation have been found in areas west of the Mississippi, but they have not infiltrated to the entire western part of the country at this point. 


These destructive insects can be found in vegetable gardens, flower gardens, fruit trees, and shrubs.  They also infest agricultural fields, golf course greens, and woodlands and parks.


Interestingly, the Japanese Beetle is not a problem in its native country like it is here, because in Japan this pest's natural predators keep it under control. If you do have Japanese Beetles that have grown out of the larval stage, using a product such as Safer® Brand Japanese Beetle Trap, will help eliminate your problem and give you back control of your back yard.
