Gypsy Moth Assessment Enrollment

York County residents living on wooded property who are seeing Gypsy Moth on their property can contact the Extension office for inclusion in a possible suppression spraying in 2018. Enrollment ends on July 31, 2017.

Highly favored species include apple, aspen, basswood, beech, birches (gray, white, and river), boxelder, hawthorn, larch, oaks (all species), willows, and witch hazel. Older larvae also will feed on hemlock, pines, spruces, northern white cedar, and other conifers. A tree begins to significantly suffer when 30 percent or more of its leaf surface is lost.

Program Criteria
This is a forested residential program. These are the criteria as of June, 2015 and may change at the discretion of Pennsylvania DCNR. In order to be considered for inclusion in the program the following criteria must be met:

  1. This is open to York County Residents ONLY. Consult your County for available programs.
  2. A minimum count of 250 gypsy moth egg masses per acre or significant danger of blow-in.
  3. Heavily wooded (over 50% of area near the home covered by tree crown) and have a permanent dwelling on the property within 200 feet of the forest.
  4. Have trees composed of at least 25% highly favored species that are at least 25 feet in height. Highly favored species include apple, aspen, basswood, beech, birches (gray, white, and river), boxelder, hawthorn, larch, oaks (all species), willows, and witch hazel. Maples, tulip poplar, locust and pines are NOT highly favored species.  Lots with a few ornamental trees, or hedgerow type groupings are not considered forested.
  5. Have 25 acres of heavily wooded land in the area around the property. If it is a small island of trees in the midst of fields or open lots, it will not qualify. 
  6. Twenty-five acres are necessary to set a spray block, please speak to your neighbors and make application together, because they will become part of a spray block with you.

There is no guarantee of a spray program being established in York County because the extent of the problem is not yet known. If there is a spray program, cost to the homeowners will be determined by the County. Payment will be due in October.
