Protect Your Home from Caterpillar Damage — Pressure Wash Only, No Chemicals

Get Your Free Estimate ☎ (650) 248-0727

If you live under mature oak trees on the Bay Area Peninsula, you know the problem — thousands of caterpillars dropping onto your roof, siding, windows, and outdoor living spaces. The droppings stain surfaces, clog gutters, and create a mess that regular cleaning can’t handle. Miller’s Pressure Washing offers professional caterpillar mitigation using high-pressure water only — no chemicals, fully compliant with local city regulations.

Why Caterpillar Infestations Are a Serious Problem

Oak tree caterpillars — including tussock moths and oakworms — don’t just look bad. They cause real, expensive damage to your property:

✓ Roof damage — Caterpillar droppings and silk accumulate on shingles, trapping moisture and promoting moss and algae growth
✓ Stained siding — Droppings leave dark stains on painted surfaces, stucco, and wood that get worse over time
✓ Clogged gutters — Silk, frass (droppings), and debris fill gutters and downspouts, causing water damage
✓ Window contamination — Droppings and silk coat windows, reducing light and requiring specialized cleaning
✓ Outdoor living disruption — Patios, decks, and furniture become unusable during heavy infestations
✓ Insurance risk — Neglected roofs with organic buildup can trigger insurance non-renewal notices

Our Caterpillar Mitigation Process

1. Property Assessment

We evaluate the extent of the infestation, identify affected surfaces, and create a targeted treatment plan for your specific property.

2. High-Pressure Tree Treatment

Using high-pressure water only (no chemicals), we significantly reduce the caterpillar population on affected trees and branches. Fully compliant with local city regulations.

3. Roof & Gutter Cleaning

Complete removal of caterpillar debris, droppings, silk, and organic buildup from your entire roof system and gutters.

4. House Wash & Surface Restoration

Full exterior soft wash to remove caterpillar staining from siding, trim, eaves, and all affected surfaces. Your home looks new again.

⚠ Important: Mitigation, Not Elimination

Due to local city regulations restricting chemical use, our service uses high-pressure water only. This significantly reduces the caterpillar population and removes all debris and damage from your property. However, complete elimination requires integrated pest management beyond pressure washing. We recommend consulting a licensed arborist for ongoing tree treatment if infestations persist year over year.
