Tree Pests is a collaborative effort of several state and federal agencies to keep citizens informed of the latest invasive insect and disease threats to Missouri’s trees. Whether you have a single tree in your yard or acres of woodlands on your property, this site is for you.

Do you know that humans are a primary way these invasive pests are spread? It’s true! Whether through moving firewood or wood to make furniture and crafts, we enable these hitchhiking freeloaders to spread from infected areas to noninfected ones. 

The invasive species to be on the lookout for in Missouri are emerald ash borer, thousand cankers disease, Asian longhorned beetle, pine shoot beetle and gypsy moth. To learn more about these invasive species and some troublesome native species, see the Tree Pests publications listed below. The “slow the spread” pages in the Tree Pest publications contain the latest tips on how you can help us in the fight against these invasive threats.
