Willow Flea Beetles: Annual Invasion & Systemic Prevention

Black bugs from backyard willow cover house/patio yearly. Likely willow flea beetles.

Current Year

• Spray foliage with carbaryl (Sevin), spinosad, bifenthrin, or permethrin.
• Orthene (systemic) lasts longer.
• Repeat weekly until gone.
• Won’t kill tree unless multi-year total defoliation.

Next Spring Prevention

1. Soil drench with imidacloprid (Bayer Advanced) at bud break.
2. Season-long protection.

Non-chemical: tolerate; beetles are seasonal. Tree survives.
