Summit Caterpillar & Webworm Control Hose-End Quart — 1 qt White, Concentrated Biological Spray, Easy Attach

Summit 021-6 is a hose-end quart formulation designed to control caterpillars and webworms on shade and fruit trees when diluted with water.

This concentrated, biological insect control mixes with water to produce between 12 and 24 gallons of spray, giving homeowners an easy, time-saving way to treat outdoor trees and shrubs. Packaged as a one-quart hose-end applicator, the product clicks directly onto a garden hose so you can apply without measuring jugs or separate sprayers. The white quart container is formulated for outdoor use and is intended to reduce visible caterpillar and webworm activity when applied according to label instructions.

How do I apply this hose-end caterpillar and webworm control?

Attach the Summit quart to a standard garden hose, turn on the water, and sweep the spray over infested foliage until leaves are evenly covered. Application is simple and fast because the unit meters concentrate and water through the hose-end mechanism.

• Attach quart to hose and set water pressure to steady flow.
• Sweep nozzle across canopy, coating leaves and branches.
• Treat until run-off is visible for thorough coverage.
• Rinse equipment after use and store upright in a cool place.

How many gallons of spray will one quart make, and how much area can that cover?

Each one-quart hose-end unit yields approximately 12 to 24 gallons of ready-to-use spray depending on the dilution rate and the hose-end setting. Coverage depends on tree size and spray density; heavier infestations require more spray per tree.

• Produces 12–24 gallons of spray when mixed with water.
• Low-volume spray treats small trees and shrubs efficiently.
• Higher-volume spraying needed for large shade or fruit trees.
• Estimate coverage by tree canopy size and desired thoroughness.

Is this safe to use around gardens, people, and pets?

The product is a biological insect control intended for outdoor use on trees and shrubs and should be used following all label directions to minimize non-target exposure. Avoid spraying edible parts of fruit close to harvest time and keep people and pets out of the treatment area until spray has settled and foliage is dry.

• Use outdoors on shade and fruit trees as labeled.
• Keep children and pets away until foliage dries.
• Follow label timing for applications near harvestable fruit.
• Store container sealed and upright away from direct heat.

When should I spray to get the best results against caterpillars and webworms?

Apply at the first sign of caterpillar or webworm activity and repeat according to the product label and pest pressure. Treating early in the outbreak, when larvae are small, improves coverage and effectiveness while minimizing the need for repeated heavy applications.

• Apply at first sighting of larvae or webbing.
• Repeat applications as recommended on the product label.
• Target morning or evening to reduce drift and avoid heat stress.
• Inspect treated areas regularly and reapply if new activity appears.
