State Agriculture and Health officials announced that the Asian Tiger mosquito (Aedes albopictus) has been identified for the first time in Vermont. This normally tropical/subtropical species is a known disease vector for Zika, chikungunya and dengue viruses, infecting humans in countries where these diseases are present. The mosquitoes found in Vermont do not currently carry these viruses. Natalie Kwit, public health veterinarian with the Vermont Department of Health, said that while the discovery of Aedes albopictus in the state is notable, Vermont's climate is currently inhospitable for the mosquito species for most of the year, making it unlikely they will be spreading new diseases here any time soon. "The diseases they can carry are not endemic to our area, and in fact are rarely found anywhere in the United States," said Kwit. For more information, visit Vermont's Mosquito Surveillance Program.

Invasive crayfish (also called crawdads) displace crayfish species naturally found in bodies of water ("native" species). They introduce disease, hurt fishing, and harm aquatic ecosystems. Our best hope of controlling them is to prevent their introduction to new locations.

An emerald ash borer (EAB) beetle was detected in a tree located in Londonderry, VT. The mapped area in Vermont (PDF | 1.25 MB) to which "Slow-the-Spread" recommendations apply now covers:

  • All of Londonderry, Windham, and Landgrove;
  • Most of Jamaica, Winhall, Peru, Weston, Andover and Grafton; and
  • Extends into Chester, Townshend, Stratton, Athens, Mount Tabor, and Wardsboro.

October means that non-flight season Recommendations to Slow the Spread of Emerald Ash Borer are now in effect when moving ash from the infested area. With the heating season underway, and firewood deliveries actively occurring, it’s important to remember that untreated ash firewood should never move out of infested areas. Be sure that your purchase or transportation of both log length and split firewood will not unnecessarily spread EAB. There’s a lot of spread to slow: While the infested area map shows that high-risk areas for EAB include many towns, visibly infested trees still remain rare in Vermont. You can help by following the "Slow-the-Spread" recommendations.

Report feral hogs, don't shoot them. The take of feral hogs is prohibited on conservation areas and other lands owned, leased, or managed by the Conservation Department. Hunting hogs on other lands is strongly discouraged. Instead, report feral hog sightings to 573-522-4115, extension 3296 or online. The Conservation Department and the U.S. Department of Agriculture Animal and Plant Health Inspection Service, along with other partners and hundreds of private landowners, are working to eradicate feral hogs in Missouri. When hunters shoot feral hogs, it complicates efforts to remove these pests. Hogs are social animals that travel in groups called sounders. Shooting one or two hogs scatters the sounder and makes trapping efforts aimed at catching the entire group at once more difficult, because hogs become trap-shy and more wary of baited sites. With their high reproductive rate, removing one or two hogs does not help to reduce populations. Anyone who observes a feral hog or damage caused by feral hogs should report it to the Conservation Department rather than shooting the animal so we can work together towards eradication.
