Sandy Boeckh believes that there is still time to build those pheromone traps (described in last week’s eBlast and now found on PaBIA’s website) for the male gypsy moths. Look at the two pictures she’s shared: one – the moth’s caterpillars on the trunk of a pine, turning “V” shaped as they prepare to pupate and the second – the pupae hanging in the pine trees~

David Bywater suggested that TreeAzin injections (used for Introduced Pine Sawfly) also are effective against Gypsy Moths. It would be interesting to know if folks who did these a couple years ago to protect their pines against pine sawflies have fewer gypsy moths. No one is sure how long it lasts.

Also, once the gypsy moths lay their egg masses, these can be scraped off trees, railings, structures, etc into a bucket of soapy water and this will prevent the eggs from hatching next spring.
