Japanese Beetles Are Here To Stay!

Japanese beetles have been making
their slow march across the country
since first being inadvertently
introduced to the New Jersey area in
1916, feeding on over 300 different plant
varieties. They are a species of the

scarab beetle. Their larvae feeds on
roots of plants, especially turf, adding
another subterranean turf enemy to
deal with. The adult beetle skeletonizes
leaves as they eat
out the softer leaf
tissues between
the veins in
addition to the
fruit of plants
if available. As
with so many non
native invaders, Japanese beetles have
natural enemies in their native land that
keep them in check, here in the states
we have no such natural enemy to keep
them under control. Over the past few
years we have seen their numbers
grow, a population growth that we can
expect to continue until they will likely
plateau... but be assured of this they
are here to stay.

Control options available would be
traps, hand picking, biological control
by introducing other predator parasites
and of course chemical controls. Traps
can be satisfying to use because of
the large number of beetles caught but
they rely on pheromones to attract the
beetles. Japanese beetles intoxicated
with pheromones (particularly those
they think are from the opposite sex)
are not very good flyers and most
end up missing the trap and landing
on the plants they are intended to
protect. The best placement for traps
would therefore be on your neighbor’s
property rather than your own if that can
be arranged. Hand picking, physically
removing and placing in soapy water to
prevent escape and eventually death,
is not likely to be the idea of a good time
for most. Biological controls could be
considered, though there seems to be

limited availability. Natural repellents
such as catnip, chives and garlic may
offer some deterrent for vegetable
gardens. Chemical controls are for now
the most effective at targeting beetles
and larvae on specific trees, turf and
plants. Make sure the insecticide used
is labeled for the use intended or call
to schedule a treatment to be applied
to control.
