How to Get Rid of Japanese Beetles

Japanese Beetles eat the leaves of your plants and its roots which leave your plant looking entirely destroyed. Learn how to get rid of Japanese Beetles with Ortho products.

At the end of June, the sun is shining, and you can finally enjoy the beautiful weather in your garden filled with flowers of a thousand colours... but only the skeleton of the leaves remains and everything has been devoured. The culprit: the Japanese beetle, a polyphagous beetle that feeds on more than 300 species of ornamental plants, perennials, trees, shrubs and annual flowers.

The Japanese beetle can be distinguished from other beetles of the same family, such as the common chafer or the European chafer, by its colour: the thorax, abdomen and head of this insect are metallic green.

In this article, you'll learn how to get rid of Japanese beetles by using Ortho® Beetle B Gon Max™ Beetle Killer.Japanese Beetles as Grubs

Japanese Beetles are born as grubs and are known for eating grass at the roots which in turn, leaves patches of dead grass on your lawn. Grubs are born and bred 8cm beneath the grass turf surface and spend the winter season continuing through its growth cycle. They then turn into adult Japanese beetles by the summertime.

Should grubs attack your lawn, it is likely that you may have to redo your entire lawn at great expense to get rid of the grub problem.

How to Recognize a Japanese Beetle Infestation

At the beginning of summer, when temperatures range between 21ºC and 35ºC, the adult beetles emerge from the ground to feed and reproduce. It is at this time that they can be seen flying, often by the dozens, in the direction of light sources that attract them. If you see them busy in your trees, shrubs or flower beds, you can consider that you have an infestation and that it is better to act quickly.

Recognizing a grub infestation before seeing a fully blown-out Japanese beetle infestation is also a proactive approach to preventing infestations in general. In the late summer season, dig 8cm deep into the turf of your grass to see if any grubs exist.
