CanopyShield™ Tree Protection
Comprehensive protection for your valuable trees against pests and diseases.
What CanopyShield™ Protects Against
California Oak Moth
Larvae feed voraciously on oak leaves, causing severe defoliation and stress to trees
Fall Cankerworm
Spring-emerging caterpillars that strip foliage from deciduous trees and oaks
Western Tussock Moth
Hairy caterpillars that cause extensive leaf damage and tree decline
How CanopyShield™ Works
Biological Larval Control
We apply Bacillus thuringiensis (Bt), a naturally occurring soil bacterium that specifically targets caterpillar larvae. When ingested, it stops feeding immediately and eliminates larvae within days without affecting other insects.
Foliar Phosphite Defense
Phosphite compounds strengthen the tree's own immune response, triggering natural defense mechanisms that make foliage more resistant to pest damage and disease.
Surfactant Coverage
Professional-grade surfactants ensure complete coverage of leaf surfaces, maximizing adhesion and penetration of both biological and nutritional components throughout the canopy.
When to Apply
Timing is critical for CanopyShield™ effectiveness. We monitor local pest populations and apply treatments during optimal windows:
Spring Applications
Target early-season caterpillar emergence before significant damage occurs
Fall Applications
Address fall cankerworm and late-season pest pressure while strengthening winter defenses
Why It's Effective
- ✓ Targets caterpillars specifically without harming beneficial insects
- ✓ Strengthens tree's natural immune defenses
- ✓ Professional application ensures complete canopy coverage
- ✓ Preventive approach stops damage before it occurs

Safety & Environmental Responsibility
Targeted & Environmentally Safe
Bacillus thuringiensis (Bt) is a naturally occurring bacterium that specifically targets caterpillar larvae. It does not harm bees, butterflies, birds, or other beneficial insects. Phosphite compounds are derived from natural phosphorus sources and enhance tree health without toxic residues.
Ecosystem-Friendly
Our approach protects your oaks while maintaining the broader ecological balance. Beneficial insects continue their work, birds find uncontaminated food sources, and your landscape ecosystem remains healthy and vibrant.
