Step #1: Identify EAB Infestation Early

To save your ash trees, early detection is critical. Here’s how you can spot an EAB infestation:

• Look for Adult Beetles: These are metallic green and about 1/2 inch long.
• Check for Thinning Leaves: Infested trees often have thinning leaves at the top.
• Inspect for D-Shaped Exit Holes: The larvae create D-shaped exit holes in the bark.
• Watch for Increased Woodpecker Activity: Woodpeckers feed on EAB larvae, so more birds could indicate an infestation.
• Examine the Bark: Look for vertical splits in the bark and S-shaped larval galleries beneath it.

Real-life example: Jane, a homeowner in Michigan, noticed increased woodpecker activity and small D-shaped holes in her ash tree. She acted quickly, calling in a professional arborist who confirmed the presence of EAB and began treatment immediately.

Step #2: Engage in Prompt Treatment

Acting swiftly can save your tree from EAB devastation. Here are your options:

• Soil Drenching: Apply insecticide to the soil to be absorbed by the roots.
• Trunk Injection: Inject insecticide directly into the tree’s trunk for fast action.
• Bark Spray: Spray the bark with insecticide to prevent larvae from penetrating.
• Canopy Spray: Target the adult beetles by spraying the tree’s canopy.

Pro tip: Always hire a certified arborist for pesticide applications to ensure safety and effectiveness.

Step #3: Know When to Remove a Tree

Sometimes, saving a tree is not feasible. If your tree has lost more than 50% of its canopy, removal is often the best option to prevent hazards. Dead trees can fall, posing risks to property and people.

Case Study: The City of Chicago faced a severe EAB infestation, leading to the removal of thousands of trees. By implementing strategic removal and replanting programs, they managed to mitigate the impact while planning for future urban forestry resilience.

Step #4: Prevent Future Infestations

Once you've treated or removed infested trees, prevention becomes key. Here’s what you can do:

• Regular Inspections: Have trees inspected by a professional annually.
• Diversity in Planting: Plant a variety of tree species to prevent widespread impact.
• Community Awareness: Engage with local community efforts to monitor and manage EAB.
