Cutter Backyard Bug Control Spray Directions | QuickFlip Setup

Connect the QuickFlip sprayer to a garden hose, turn on the water, remove the safety tab, pull the switch back, and spray until the area is wet — the concentrate mixes automatically as you go.

One wrong move with the hose-end sprayer and the concentrate never mixes right. The Cutter Backyard Bug Control Spray Concentrate covers up to 5,000 square feet of lawn and keeps mosquitoes, ticks, ants, and earwigs gone for up to 12 weeks — but only if the QuickFlip switch goes the right direction first. Below is the exact sequence from the label, plus the mistakes that waste the bottle.

What Comes In The Bottle

The 32-ounce bottle is ready to attach to a standard garden hose. The active ingredient is lambda-cyhalothrin at 0.16 percent, a synthetic pyrethroid that targets insects on contact and leaves a residual barrier. It kills mosquitoes, house crickets, carpenter ants, harvester ants, lady beetles, earwigs, aphids, chinch bugs, flies, leafhoppers, ticks, and several other listed pests. The concentrate is not pre-mixed for a tank sprayer — it dilutes through the QuickFlip hose-end sprayer as water flows through.

The Correct Way to Use the QuickFlip Sprayer

The QuickFlip hose-end sprayer comes attached to the bottle. It mixes concentrate and water at the right ratio automatically. These steps match the official instructions from Cutter.

1. Shake the bottle well before connecting anything.
2. Wet the lawn a few hours before treatment. Dry grass soaks up the spray unevenly. Pre-watering helps the barrier spread.
3. Push the switch fully forward toward the nozzle. This is the OFF position. Any other position will spill concentrate before you are ready.
4. Connect a garden hose to the sprayer nozzle. Hand-tighten only — overtightening can crack the plastic.
5. Turn on the water at the faucet. Extend the hose to the farthest corner of the treatment area. Always spray from the farthest point back toward the faucet to avoid walking through wet spray.
6. Remove the safety tab from the right side of the sprayer. Pull it straight out. You can reinstall it later for storage or discard it.
7. Pull the switch backward toward the hose connection using your thumb. Water begins flowing through the concentrate chamber.
8. Spray until the surface is wet. Walk at a steady pace with an even side-to-side motion, slightly overlapping each pass. Do not spray to the point of runoff.
9. Push the switch forward toward the nozzle to stop spraying. Turn off the water at the faucet.
10. Relieve pressure by pulling the switch back toward the hose until water stops dripping. Then disconnect the hose.
11. Store the bottle with the switch in the OFF position and the safety tab reinstalled. Keep it in a cool area away from heat, sunlight, or open flame.

The switch moves toward the hose for ON and toward the nozzle for OFF — that backward-forward motion is the most common confusion on the first use.

What To Treat and What To Skip

Use the concentrate on lawns, ornamental plants, shrubs, and the exterior of the home. Spray until the surface is wet, but never to the point of runoff. The label permits application to non-bearing fruit and nut trees and to ornamentals in the landscape. Do not apply to vegetables or to fruit trees that are bearing fruit unless it is very early in the growing season — the chemical takes time to break down.

Coverage and Duration

One 32-ounce bottle treats up to 5,000 square feet of lawn. A single application can control target insects for up to 12 weeks when applied correctly in early spring. Re-treatment may be needed sooner if heavy rain falls within 24 hours of application. The label does not allow application during rain.

Regional Restrictions You Need To Know

Residents of New York State must follow an additional rule. Do not apply the concentrate within 100 feet of a coastal marsh or any stream that drains directly into one. On private land anywhere in the United States, keep applications away from ponds, streams, storm sewers, and any area that drains into natural water bodies. The concentrated chemical is toxic to fish, tadpoles, and aquatic invertebrates at very low concentrations.

What Happens To Pollinators and Beneficial Insects

Lambda-cyhalothrin is highly toxic to bees. Do not apply the spray on plants that are in bloom. Treat in the early morning or late evening when honeybees and other pollinators are least active. Do not allow the spray to drift onto flowering weeds or clover in the lawn. The product also kills beneficial insects like fireflies and lady beetles indiscriminately, which is one reason to spot-treat only where pests are actually present.

The table below summarizes the key facts for a quick reference before you mix.

How To Avoid Killing Pollinators

The single most important precaution is timing. Apply in the early morning or late evening when bees are not foraging. Do not spray blooming plants — not just flowers in your garden beds, but also clover and dandelions in the lawn. Check the treatment area for visible pollinators before you start. If you see bees on any plants, delay the application. The label also prohibits application while the treatment area has standing water or while rain is falling.

What Safely Follows the Application

Keep people and pets off the treated area until the spray has fully dried. Drying time depends on temperature, humidity, and sun exposure — typically one to two hours in moderate conditions. Once dry, the barrier is safe for normal activity. Do not let children play on wet grass. Wash hands and any exposed skin with soap and water after handling the concentrate or the sprayer.

The table below covers the safety and compatibility details that most people miss until it is too late.

Dos And Don’ts That Save The Bottle

Do measure the lawn area so you use the right rate — oversaturating a small patch wastes concentrate and increases runoff risk. Do water the grass a few hours ahead of time, but not so much that puddles remain. Do spray in calm wind to avoid drift onto neighboring plants or flower beds. Do not spray onto driveways, patios, or sidewalks where it can wash into storm drains. Do not pour any leftover mixture down a drain. The bottle is designed to empty fully through normal spraying; if any remain after the job, close it with the safety tab and store it upright for the next application.

This Is How You Check It Worked

If the application went correctly, you should see fewer active insects within 24 to 48 hours. Mosquito levels will drop noticeably after two to three days. Ticks and ants may take slightly longer because the barrier needs to contact them as they move through the treated grass. The product works on contact and by residue — the insect simply walks across the treated surface and picks up the chemical. If you still see active pests after a full week, check whether the spray covered the area evenly and whether rain washed it off within the first day. Spot-treat any missed patches using the same procedure.

If the QuickFlip sprayer did not mix the concentrate properly — you see undiluted blue liquid pooling or no color at all — the switch was likely in the wrong position. Push it fully forward to OFF before connecting the hose, then pull it fully back to ON before spraying. Partial positions restrict water flow through the concentrate chamber and produce incorrect mixing.
