In neighborhoods where the infestation of this beetle
is widespread, there should be a combined effort in the area to maximize the
control effects. In other words, if you are the only one treating for
these pests, your results will probably be minimal.
There are two schools of thought, when it comes to spraying for the Elm
Leaf Beetle. Many people prefer to spray the trunk of infested trees,
which does not affect larvae which have already done their damage. This
type of spraying is easier than foliage spraying. Foliage spraying is most
effective but should not be attempted unless you have confidence in your ability
to reach and treat all foliage, killing as many beetle larvae as possible.
The second option (foliage spraying) is the obvious top choice because (a)
offending pests are killed before too much damage is done (when spraying is
timed correctly) and (b) a wider variety of products is available. There
are other pros and cons to the treatment methods. When in doubt, use
both. Safety first! If you cannot treat the tree or trees in a safe
manner, minimizing risk to people, pets and environment, it would be best to
leave the job to a professional.
Products Used to Control Elm Leaf
When found indoors, simply using your vacuum to dispose
of a few invading beetles usually does the trick. If needed, however,
there are a couple of professional aerosols that can be used to treat cracks and
crevices: CB Airdevil and CB
Outdoors, you can choose to spray
foliage, tree trunk or both. Best results are achieved when foliage
spraying is properly timed. There are two basic types of insecticides that
can be sprayed for Elm Leaf Beetle control: contact and systemic.
Systemic insecticides (if used before Elm Leaf Beetle larvae populations get out
of control) can be very effective. The main thing to consider before using
a systemic insecticide is length of time from application to pests being killed
by the product. A systemic insecticide is taken up by the plant and
carried throughout the plant's system, working from the inside out. Also,
the best systemic insecticide that is labeled for controlling Elm Leaf Beetles
is Acephate (sometimes called Orthene), an insecticide with a very distinctive,
unpleasant odor. More about Acephate in control summary.
There are several contact pesticides labeled for spraying ornamentals or trees
for pests such as the elm leaf beetle: Suspend SC,
Talstar One, Demon Max and
Dragnet (professional strength Permethrin) just to name a few. Suspend SC,
Talstar One and
Dragnet are odorless or super low odor. Demon Max is low
