The quarantine- At this time there are 13 counties in PA that are under an active quarantine. This restricts movement of plant material and many other materials that may transport eggs or any stage of SL to a non-infested area. Philadelphia, Chester, and Montgomery are all under quarantine at this time and we expect the list to grow well past the current 13.
Egg Masses – The egg masses look like peanut butter smeared on a tree. It may be on the side of a home, a car, a fence post or any smooth vertical structure. One of the main control strategies is scraping egg masses and destroying them. Most important is that the egg masses are destroyed. If burning is legal in your township, that is one option or double bagging the egg masses and putting them in the garbage.
Bait Trees – As mentioned above, the Tree of Heaven is crucial to their reproduction. By reducing the amount of Tree of Heaven and then treating a few remaining specimens with a systemic insecticide, there have been satisfactory results in that many SL were eradicated.
Sticky Tape – This, again, takes advantage of the Tree of Heaven being important to their reproduction. By putting sticky tape on Tree of Heaven, or even other infested trees you encounter, you can capture and destroy SLF.
