Pests

What are those purple boxes hanging from trees in Chester County PA??  They are lures and traps for a devastating insect we expect to see soon! Oh no!  Emerald Ash Borer is an introduced species of insect that attacks ash trees.  Control is difficult if not impossible. Infected trees must be removed and destroyed. Prevention is the best way to avoid problems!


PEST ALERT!  IF YOU HAVE ASH TREES! Contact our office for important information about Emerald Ash Borer.

 EMERALD ASH BORER!

You may lose all your Ash (Fraxinus sp.) trees to these pests.

In an attempt to erradicate Emerald Ash Borer, Argriculture officials in Maryland have begun cutting down 25,000 trees in an 11,500-acre swath of forrested and developed land in southern Prince George's County.

Illinois, Indiana, Michigan, Ohio and now, Maryland AND PENNSYLVANIA have taken steps to erradicate the bug.  It is important to get rid of it by spring.  That is when the insects, which are currently in larval form living in the bark of infested trees, will emerge as adults.

The insect was found in the HARRISBURG area and suspected in KENNETT SQUARE!   The goal is often to remove all of the ash trees within a 1.5 mile zone around the infested tree.  The state of Maryland has also quarantined all ash wood and all hardwood firewood from leaving the area of Prince George's.  If you see one, attempt to contain it in a baggie and contact the office.
