Controlling Eastern Tent Caterpillars on Dwarf Cherry Trees

Identification

Webs in branch crotches with caterpillars = eastern tent caterpillar. Hosts: cherry, apple, crabapple, etc.

Control Options

• Mechanical: Remove tents early morning/late afternoon (caterpillars inside). Wear gloves—hairs irritate. Crush or soak in soapy water. Never burn.
• Chemical: Bt (Bacillus thuringiensis) on young caterpillars. Carbaryl, methoxychlor, malathion for older. Tents protect larvae—spray penetration difficult.

Outlook

Tree re-leafs after defoliation. Nests are cosmetic issue.

Key Takeaway

Early tent removal or Bt application controls eastern tent caterpillars effectively. Trees recover fully.
