The Snyder County Conservation District (SCCD) has created this web page to help lead visitors towards informative websites and organizations familiar with certain insect pests and invasive plants.


 Spotted Lanternfly


Currently a quarantine is in place for thirteen (13) southeastern Pennsylvania counties to try to stop the movement of the Spotted Lanternfly. This pest is a native of China, and could possibly work its way into our area. The destructive insect feeds on a variety of plants including grapes, apples, peaches, ailanthus, willow, hops and certain ornamental plants.

Snyder County is currently not within the PA quarantine zone. However, all Pennsylvania residents and guests are asked to do their part in controlling this pest. For more information on this pest go to the links below:

For more information or wish to report a siting, contact your nearest Penn State Extension office or any of the contacts listed within the above web pages.

 Gypsy Moth

In 2007, gypsy moth caterpillars chewed their way into Snyder County landowner’s woodlots after more than a ten year hiatus. To help combat the pesky leaf eaters in 2008, a joint effort between the Snyder County Commissioners, Snyder County Conservation District and the Department of Conservation & Natural Resources' (DCNR) PA Bureau of Forestry treated close to 1,200 acres in seven townships with Bt (Bacillus thuringiensis), a bacterial spray for leaf eating caterpillars. Landowners were responsible for paying roughly half the spray costs while DCNR's Bureau of Forestry cost shared an specific amount.

Since then, either gypsy moth counts have been low or funding programs have been limited. At this time, there is no county sponsored program at this time.

For more information, or you suspect that you have gypsy moth caterpillars or egg masses, leave a message with the DCNR's Bald Eagle State Forest District office near Laurelton at 570-922-3344 regarding gypsy moths and other forest pests.

 Other Insect Identification

There are other caterpillar pests currently present in Snyder County. Many presume that what they see is the gypsy moth in its larval stage. However, that may not be the case. Please check out the Caterpillar Photo Chart in the "Gypsy Moth Downloads" section at the right hand side of this web page.

For more information, please call the DCNR Bureau of Forestry office near Laurelton (along PA Route 45) at 570-922-3344.

 Invasive Plants

There are many trees, shrubs, grasses and other plants that are not native and are invasive to Pennsylvania. While some can be "tamed," many need to be managed with great care and planning.

Some Conservation District staff are familiar with some of invasive plants. However, there are other groups that are far more knowledgeable. Below are a list of links and contacts related to these troublesome plants.
