Japanese beetles are incredibly destructive pests that eat foliage from your trees and plants, leaving
only the skeleton of the leaf. Japanese beetles are voracious eaters and they can come in swarms. It is
important to get rid of Japanese beetles as soon as you see them in your yard. Much research has been
put into Japanese beetle control and there are several effective ways to eliminate them.
Traps are Tricky
Commercially available traps work in one of two ways. They emit the smell of
pheromes attractive to Japanese beetles or they emit the smell of food that Japanese
beetles like. The beetles are lured to the smell and fly into the top of a bag from which they
cannot escape. These traps are very effective. Too effective, in fact, because they draw
Japanese beetles to your yard from other areas. If you use a trap, place it far away from
your garden and empty the bag regularly.
Netting – Ugh
Another effective way to control
Japanese beetles is to place netting over
your bushes. Japanese beetles really
enjoy rose bushes and rose bushes are an
appropriate sized plant to put netting.
The downside, of course, is that you can’t
enjoy your beautiful roses.
You Can Easily Make a Spray
Insecticidal soap. The term sounds a little scary, but it is simply a mixture of soap, oil and
water that you can mix yourself and apply to foliage to get rid of Japanese beetles. Using an
empty spray bottle, mix a teaspoon of dishwasher detergent and a teaspoon of oil (any oil
will do – cooking, vegetable, olive, etc.) with tap water. Spray the Japanese beetles with
the mixture. You should spray both the tops and bottoms of all leaves in the area for
completely effective control.
Milky spore is a commercially available product that
kills Japanese beetles and their grubs that grow in your
grass. It is a bacteria that attacks many insect,
including Japanese beetles. It is applied to the grass
where it kills the grubs. Milky Spore takes three years
to be fully effective, but since it is a growing bacteria it
will last up to ten years. You might want to consider

The neem tree (found in India and
southern Asia) produces an oil that is
repugnent to Japanese beetles. Neem

Japanese beetles. Insecticides should be used as a last
resort due to toxic nature of the product. Never spray
insecticides on or near your vegetable garden. Always
follow the label directions carefully.
Japanese Beetles Won’t Eat …

Maple trees, boxwoods, boxelders, oaks, magnolias, hollydogwoods, ash trees, holly trees
and lilacs. Japanese beetles do not eat these plants.

Left unchecked, Japanese beetles can do tremendous damage to trees, roses and other plants on your lawn. However,
you can control Japanese beetles. Traps work, but they may attract more beetles to your lawn. You should keep traps far
away from your garden. It is easy to make your own insecticidal spray using water, oil and dishwashing soap. Neem products
kill and repel Japanese beetles and commercially available insecticides will also work.
