Think about it: the trees cut for firewood often die due to insects or disease. Don't spread pests – buy firewood where you burn it.

#FirewoodMonth #InvasiveSpecies #Entomology #firewood 🧪🌍🍁

OCTOBER IS FIREWOOD MONTH. FIREWOOD ISN'T DEAD: When 1,045 pieces of firewood were studied in Michigan, scientists found live wood boring beetles in 23%-- and another 41% had evidence of previous infestation. 77% of Americans live less than 10 miles from a wooded area. JUST GET OUT AND WALK: Taking a walk creates a 12.4% drop in stress hormones, a 1.4% drop in blood pressure, and a 5.8% drop in heart rate. 92% of Americans have at least 1 tree on their property. 65% of people use firewood: 53% for home heating, 49% for recreation, and many for both. TRANSPORTING FIREWOOD CAN SPREAD PESTS: Trees in ALL 50 STATES AND 10 CANADIAN PROVINCES ARE AT RISK of attack by invasive species if people move infested or diseased firewood. You can help: Buy local firewood. BUY IT WHERE YOU BURN IT. Learn more at DontMoveFirewood.org. For a complete list of sources, please visit dontmovefirewood.org/octoberisfirewoodmonth

Don’t confuse #TreeOfHeaven (Ailanthus altissima) with important native lookalikes like walnut or sumac. Tree of Heaven has smooth bark, smooth leaf edges with a single tooth at the base and gives off a strong odor. Learn more here: www.canr.msu.edu/resources/a-... #InvasiveSpecies #Entomology 🧪🌍🍁

Tree of Heaven: What to Look For. Pinnately compound leaves where small, pointed leaflets are attached to a central stalk. Bark is smooth and resembles elephant skin or cantaloupe skin. Leaflets are smooth and have a small glandular "tooth" at the base. Most notably, a strong odor --often compared to rancid peanut butter-- that researchers believe may attract Spotted Lanternfly.

Orange infographic titled, "Beware of EAB look-alikes!" Three similar looking beetles are pictured: Bronze Birch Borer, Two-lined Chestnut Borer, and Six-spotted Tiger Beetle. The caption on the right features a picture of an Emerald Ash Borer and says, "Emerald Ash Borer: Adult emerald ash borers are about 3/8 to 5/8 inch long and are active from May-September. They depend entirely on ash trees for every stage of their life cycle, so the presence of ash trees is a key context clue for identification."
