Gypsy Moths Want to Devour Your Favorite Destinations

The gypsy moth larva, or caterpillar, is the life stage that causes destruction.

Memorial Day Weekend means hitting the road for many of us – vacations, camping, or even moving to a new home. But watch out for an invasive pest that also enjoys new destinations—the destructive gypsy moth. Gypsy moth caterpillars can defoliate, weaken and kill more than 300 different species of trees and shrubs. Since 1970, more than 83 million acres have been defoliated by the gypsy moth in the U.S.

This destructive insect is always interested in a free ride to new locales where its caterpillars can feast.  And Americans are on the move in May—that’s why it’s National Moving Month—giving gypsy moths plenty of opportunities to spread.

Residential moves account for 85 percent of all new gypsy moth infestations, and approximately 40 million Americans will relocate their households this year. Slowing the movement of the gypsy moth is the reason the U.S. Department of Agriculture asks homeowners to inspect for and remove gypsy moth egg masses from household goods before they move from an infested area to a non-infested area.

Female gypsy moths often lay their eggs on outdoor household goods like barbecue grills, deck furniture, lawn equipment, and trailers, so take some extra care when packing so those egg masses don’t move with you.  It’s easy to leave gypsy moths behind: during your vehicle and outdoor household item inspection, look for a dense mass of tan or buff colored hairs resembling a small piece of a camel hair sweater. Remove it with a putty knife or stiff brush, and dispose of it in a container of hot soapy water—that’s it!

Slow the Spread Foundation, USDA’s Forest Service & APHIS set up a region-wide strategy to stop the gypsy moth from spreading.

The USDA’s Animal and Plant Health Inspection Service (APHIS) and key partners are working hard to stop the gypsy moths, working closely with the Gypsy Moth Slow the Spread Foundation (10 states located along the leading edge of gypsy moth populations).

Even if you’re not relocating your household this month, you may be planning a getaway for the long Memorial Day holiday weekend. A close inspection of your travel trailer, boat, and all outdoor toys is a must before leaving the driveway. It’s vital because a single gypsy moth egg mass hidden under an RV bumper could contain up to 1,000 individual eggs. That means your carefree holiday could have unintended and disastrous consequences—establishing a new infestation! If you find an egg mass, remove it right away.

If you’re planning to move, you’ll want to visit YourMoveGypsyMothFree.com for more information. It will help you to understand if you must complete an inspection checklist for your outdoor household items and take it with you during your move.

Protect your destinations from the destructive potential of the gypsy moth. Fortunately, a simple inspection is all it takes to stop this pest in its tracks.

I'm from CT where we have had severe infestations. I live in a condo dominated area & when I first noticed these things I got my sticks & brooms & started crushing them. I have managed by myself to clean up several roadsides, city greens, & cemeteries. What is disappointed is the lack of action by state & local agencies. Our public works dept. consists of one guy holding the other guy's cup of coffee. There needs to be more aggressive attention to this insect because it can rapidly defoliate trees. Trees give off oxygen, absorb co2, fix nitrogen, & provide shade. Our country tends to be reactive & not proactive. Defoliating insects can indeed infect the climate globally by removing trees from the landscape. This can affect the co2:o2 balance & as well as whether we can capture a cool breeze. I think we should be attacking many pestilent insects & diseases using biologics & radiation procedures. They are using radiation to sterilize male mosquitos in Florida & with some success. If we can get enough males out to the realm, the mating will produce no eggs. We need this kind of mutation. Darwinian principles at their best. This would definitely alleviate the need for harsh pesticides that we often see causing mutations in human populations. Any number of labs, pharma comps, & universities should participate in this procedure. Figure there are several million bug species, not all pestilent & 80% residing in the equatorial regions. Think if we can target the few hundred that decimate crops, forests, spread disease, & affect animals, we could be winning a major battle & increase human comfort levels.

I live in Ashland MA....I abut the DCR Ashland State Park. After reading Webb information on Gypsy Moths I am more upset than ever. In 2014 they were in Penn, the Govt. did not get in front of the infestation from the beginning.
I now have a "grave Yard" of 70'plus tall trees. I have reached out to the State with no assistance.
We have a tragic infestation and there is NO WAY a Homeowner can handle the situation of the Gypsy Moth and the Devastation has caused by the Gypsy Moth along Ashland State Park/Warren Woods.
Please HELP!
Tell me what I can file for Assistance with Federal Govt. to get involved with the removal and destruction of infestation. Removal of dangerous DEAD TALL TREES, before someone gets hurt by falling branches etc.
Question...Why is Our Govt. NOT stopping, Not using a process to make sure we have minimal if none, insects, animals etc. being imported through immigration and trade, WHAT process is being used to secure our Homeland from disease of our agriculture???
PLEASE,PLEASE, HELP!!!! STATE OF EMERGENCY!!

@Angela - thank you for your comment. Thank you for your message about the European gypsy moth. An effective way for us to know when an invasive pest is in the area is through concerned citizens, like yourself, reporting your findings. USDA shares your concern about this invasive and destructive pest, a pest that has been in the country for over 100 years. USDA’s goal is to define the extent of the gypsy moth infestation in the U.S., to help eradicate isolated populations, and to limit the spread of gypsy moth beyond the current infested area through an active regulatory program. To foster greater awareness about the gypsy moth and the need to stop its spread, USDA is working with the U.S. Postal Service on an outreach effort to help people leave invasive pests, like gypsy moths, behind during household moves. We urge people moving households to visit the Your Move Gypsy Moth Free webpage for our moving checklist and for additional information and resources to protect against the European gypsy moth. Visit our website to learn more about our work to exclude invasive pests from imported products: www.aphis.usda.gov/aphis/ourfocus/importexport/trade/ct_trade
