Spongy moth egg masses are fuzzy, spongy, and cream or brown-colored. If you find these pests in quarantine areas, smash them, and scrape them off, so that you don’t accidentally move them to ...
When numbers of gypsy moth larvae are high, pesticides may be the most effective method of killing larvae. Available pesticides fall into two groups: microbial or biological and chemical (table 1). Microbial and biological pesticides contain living organisms that must be consumed by the pest. These include bacteria, viruses, and other organisms ...
Pheromone traps are very sensitive, meaning they attract insects present at very low densities. They are often used to detect presence of exotic pests, or for sampling, monitoring, or to determine the first appearance of a pest in an area.

To take care of the storm of bugs that had poured onto them and into the bed, he and his wife gathered up the sheets and dumped them in the wash. "Any leftovers got vacuumed up," he adds.
As a result, nine parasitoids (solitary wasps) of the spongy moth, seven of the brown-tail moth, and two predators of both moths became established in the US. Although the spongy moth was not fully controlled by these natural enemies, the frequency, duration, and severity of its outbreaks were reduced and the program was regarded as successful.
Spumaline is hydrophilic and prevents the eggs from drying out. It also serves as a protective covering which limits the ability of small wasps to parasitize the eggs. Although the male moth may live for a week or more, the female dies soon after laying her eggs. Thus, the whole of the female's adult life may take place in fewer than 24 hours.
