Here’s a closer look at the most common spring tree pests in Kansas City and what you can do to protect your property.

Top Spring Tree Pests to Watch For

Emerald Ash Borer

One of the most destructive pests in our area, the Emerald Ash Borer (EAB) targets ash trees. These small, metallic-green beetles lay eggs on the bark, and the larvae burrow underneath, cutting off a tree’s nutrient supply.

Signs to Look For:

  • Thinning ash tree canopies
  • Tiny D-shaped exit holes in the bark

Vertical splits in bark

Action Step: Inspect your ash trees regularly and avoid moving firewood, which can spread the pest. If you spot signs of EAB, contact a professional immediately for evaluation and treatment options.

Bagworms

Bagworms are a major threat to evergreen trees like cedars and junipers. These pests create small, cocoon-like bags that hang from branches and can quickly defoliate a tree.

Signs to Look For:

  • Small, spindle-shaped bags hanging from tree branches
  • Browning or thinning of evergreen foliage

Action Step: Hand-pick and destroy visible bags before June, when larvae emerge. Early action can prevent significant damage.

Japanese Beetles

These shiny green beetles are notorious for skeletonizing leaves, leaving trees looking lace-like and vulnerable. They attack a wide range of tree species and are especially active during warm mornings.

Signs to Look For:

  • Skeletonized (see-through) leaves
  • Clusters of beetles on leaves in the early morning

Action Step: In the morning, shake affected branches to dislodge beetles into a bucket of soapy water. For severe infestations, professional treatment may be necessary.

Quick Tips to Strengthen Your Trees Against Pests

Healthy trees are naturally better able to resist pests and diseases. Here are a few simple ways to keep your landscape strong this spring:

  • Mulch Smartly: Spread 2–3 inches of mulch around trees, but keep mulch a few inches away from the trunk to prevent moisture buildup and pest problems.

  • Water Deeply: During dry spells, deep watering encourages strong root growth and improves overall tree resilience.

Inspect Weekly: Early detection is critical. Check your trees once a week for unusual leaf discoloration, holes, spots, or visible insects.
