  • Keep an eye on your trees! Look at undersides of branches in December through March for small, white ovisacs. If found, note the location of the tree and, if possible, take photos of the infested branch. To avoid spreading HWA, do not collect sample branches or twigs. Report the find using one of these methods:
    • Contact us via email at This email address is being protected from spambots. You need JavaScript enabled to view it. or phone (231) 757-3707 ext. 5
    • Use the Midwest Invasive Species Information Network (MISIN) online reporting tool or MISIN smartphone app.
  • Remove birdfeeders from areas where hemlock trees are present. Birds may carry these insects to a birdfeeder where they can be picked up and transported by other birds.
  • Be mindful of your hunting and camping gear, RV’s etc. If you are in areas with hemlock trees, just brushing against an infested tree could bring these insects along for the ride! Run clothing through a dryer and wash or brush off gear and vehicles before moving to a new area.
  • Construction equipment could also spread these insects and other invasives. Ensure they are washed or brushed off before entering and leaving sites!

For a two-sided, pocket sized HWA and hemlock tree identification card please contact our office to pick one up. Great to keep on your fridge as a reminder to check your trees!
