Wasp-A-Way WAW

Q: Does Wasp-A-Way actually kill wasps or just knock them down?

It kills on contact. The dual active ingredients — tetramethrin and a pyrethroid synergist — deliver both fast knockdown and confirmed kill of wasps, hornets, yellowjackets, and scorpions. Any insects that survive initial treatment and return to the nest are killed by the residual action left in the treated nest.

Q: How far does Wasp-A-Way shoot?

Wasp-A-Way reaches nests more than 20 feet above ground. The jet spray actuator is designed so you can treat from a safe distance without getting close to an active nest. For best results, hold the can upright at arm's length and aim at the nest opening first.

Q: Does Wasp-A-Way work on yellowjackets?

Yes. Wasp-A-Way is labeled and tested for wasps, hornets, and yellowjackets. Yellowjacket nests are often underground or inside wall voids — treat the nest entrance directly and saturate as thoroughly as possible. Apply in the early morning or evening when the colony is inside the nest and activity at the entrance is low.

Q: How long does a can of Wasp-A-Way last?

Wasp-A-Way WAW-1 contains 16 oz net weight of product in a 28 oz pressurized can — one of the larger aerosol formats available in this category. A single can is sufficient to treat multiple nests in one session. Shelf life is several years when stored in a cool, dry location away from heat and open flame. Do not store above 130°F as pressure buildup can cause the container to burst.

Q: When is the best time to spray a wasp nest?

Early morning or early evening. At those times the temperature is cooler, most of the colony is inside the nest, and activity at the nest entrance is minimal. Spraying during peak daytime activity increases the risk of encountering airborne wasps. Always spray when the air is still — wind will deflect the jet and reduce coverage.

Q: Can I use Wasp-A-Way indoors?

Yes, with restrictions. Wasp-A-Way is EPA labeled for indoor use in attics and other enclosed areas where nests are built, provided food and feed are not exposed in the treatment area. Do not apply when food is present. Do not allow adults, children, or pets to enter the treated area until the spray has dried completely. Remove pets and birds and cover fish aquariums before spraying.

Q: How long do I wait before removing the nest after spraying?

Wait a full 48 hours before removing the treated nest. This allows time for any insects that were away from the nest during treatment to return and be killed by the residual action. Removing the nest too soon risks encountering surviving insects.

WASP-A-WAY is a professional-grade commercial wasp and hornet spray formulated for HVAC technicians, electrical contractors, and facilities maintenance professionals — built for the environments you actually work in, not a homeowner’s porch eave.

The petroleum distillate carrier delivers 57,200V dielectric strength (ASTM D-877) — the highest verified rating in the commercial category — while driving 0.200% Tetramethrin deep into insect cuticle for immediate contact kill. One formula handles energized equipment, enclosed spaces, and everything in between.

10x the Active Ingredient: Tetramethrin at 0.200% — ten times the concentration of Raid (0.02%) and double SpectracidePRO (0.10%). Proximity kills. A perfect shot isn’t required.
Highest Dielectric Rating in the Category: 57,200V by ASTM D-877 — verified, documented, and higher than any other commercial wasp spray on the market.
EPA Registered Indoor + Outdoor: Covers attics, crawl spaces, mechanical rooms, and wall voids. Most consumer sprays are outdoor use only.
Consistent Range — Full Can: Batch tested at multiple fill points for 18+ feet of effective spray range throughout the entire can, not just at full pressure.
Two Killers, No Filler: Tetramethrin 0.200% + Sumithrin 0.125% — both active insecticidal ingredients.High concentration, quality ingredients.
Safe Near Electrical Equipment: Petroleum distillate carrier resists electrical conduction. The test data exists and is available — ask your current supplier for the same.

Wasp-A-Way (WAW-1) | Commercial Wasp & Spray | Professional Grade

WASP-A-WAY is a commercial-grade wasp and hornet spray built from the ground up for trade professionals — not reformulated from a consumer product and repackaged for a supply house shelf. The difference shows up on the label: 0.200% Tetramethrin, the fast-knockdown pyrethroid that Raid puts in at 0.02%. That’s not a marginal improvement. It’s ten times the active knockdown ingredient per application, which means the margin for an imperfect shot — a moving target, a partial spray, an insect at the edge of the stream — is real instead of nonexistent.

Consumer wasp spray is engineered to one use case: a homeowner, clear conditions, direct shot at a visible nest on a calm morning. It doesn’t need to handle energized condenser units, attic air handlers, crawl space mechanical rooms, or a half-empty can on the second job of the day. WAW-1 does. The petroleum distillate carrier delivers 57,200V dielectric strength by ASTM D-877 — the highest verified rating in the commercial category — an EPA indoor use registration that covers the enclosed job site spaces most sprays legally can’t enter, and batch-tested range that holds 18+ feet through the full life of the can. One formula. Every environment on the work order.

Manufacturer’s Tech Note: Wasp-A-Way maintains 18+ feet of effective spray range throughout the entire can — not just at full pressure. This is the result of a multi-stage pressurization process and batch testing at multiple points in each production run, verifying consistent spray performance from first use to last. Most wasp sprays are rated at peak propellant pressure only. WAW-1 is built to perform at the end of the can the same way it performs at the start.

Where WASP-A-WAY Outperforms Consumer and “Professional” Retail Sprays

KEY FEATURE / SPECIFICATION	TRADE BENEFIT / RESULT
Tetramethrin 0.200% — Fast Knockdown Agent	10x the Active Ingredient vs. Raid: Raid contains 0.02% Tetramethrin. Wasp-A-Way contains 0.200%. At 0.02%, a perfect direct hit is required. At 0.200%, proximity is enough — insects in the spray cloud, not just the direct stream, receive a lethal dose.
57,200V Dielectric Strength (ASTM D-877)	Highest Verified Rating in the Category: Raid rates 32,500V. SpectracidePRO rates 47,300V. Wasp-A-Way rates 57,200V — tested by ASTM D-877, the standardized method. Every spray says “safe near electrical.” Only one can show you the test data.
EPA Indoor + Outdoor Registration	Goes Where the Job Goes: Most consumer sprays are outdoor use only — a propellant flammability and registration limitation. WAW-1 carries EPA indoor registration covering attics, crawl spaces, mechanical rooms, and wall voids. EPA Reg. No. 1021-1649-6381.
Batch-Tested Range — Full Can	18+ Feet Through the Last Spray: Aerosol pressure drops as propellant depletes — most retail cans perform at 10–12 feet by half-empty. Wasp-A-Way is batch tested at multiple fill points to verify 18+ feet of effective range throughout the entire can, not just at initial pressure.
Two Killers, No Filler	Tetramethrin 0.200% + Sumithrin 0.125%: Both active insecticidal ingredients. SpectracidePRO lists three active ingredients — the third is Piperonyl Butoxide, a synergist that doesn’t kill insects. WAW-1 has two killers and no synergist padding the count.
Petroleum Distillate Carrier	Faster Contact Kill + Dielectric Properties: The petroleum distillate carrier penetrates insect cuticle faster than water-based formulas, accelerating active ingredient delivery to nerve tissue. The same carrier chemistry produces the 57,200V dielectric rating and enables the indoor use registration.

Vapco Field Guide: Application Matrix

Common professional wasp and hornet spray scenarios and how WAW-1 addresses each. (★★★ = Ideal Application)

APPLICATION SCENARIO	RATING	WHY IT WORKS
Wasps (Paper Wasps, Mud Daubers)	★★★	0.200% Tetramethrin delivers fast paralysis on contact. Effective even at the spray cloud periphery — a direct hit is not required.
Hornets & Bald-Faced Hornets	★★★	High-concentration formula handles larger, more aggressive species. Batch-tested range keeps the applicator outside the defensive zone through the full can.
Yellow Jackets	★★★	Fast knockdown critical for aggressive ground and void nesters. Sumithrin 0.125% provides residual coverage for foragers returning within 48 hours of treatment.
HVAC Condensers & Electrical Enclosures	★★★	57,200V dielectric strength (ASTM D-877) — the highest in the commercial category. De-energize when practical; WAW-1 provides the greatest documented safety margin when that isn’t immediately possible.
Attic Air Handlers & Enclosed Spaces	★★★	EPA indoor registration covers attics, crawl spaces, mechanical rooms, and wall voids. Most consumer sprays cannot legally be used in these environments.
Commercial Exteriors — Rooflines, Soffits, Utility Areas	★★★	18+ feet of verified range throughout the full can. A technician on a ladder or roof with a half-empty can has the same standoff distance as one with a fresh can.
Residential — General Exterior Use	★★★	Works everywhere else too. Same formula, same performance — eaves, soffits, outbuildings, and landscaping features where nests are built.
Application Notes	NOTE	De-energize equipment when practical. Dielectric strength is a safety margin, not authorization to spray live components carelessly. Do not spray directly into open energized panels. Indoor use: Registered for enclosed spaces where nests are built — not for food-handling areas.

Application Tip: Treat nests at dusk or dawn when forager activity is lowest and the colony is most concentrated at the nest site. Apply at the labeled standoff distance — the full can maintains 18+ feet throughout its life. For nests in enclosed spaces, ensure the area is ventilated after treatment per label directions.

Why Consumer Wasp Spray Fails Where WASP-A-WAY Doesn’t

THE LIMITATION (Consumer / Retail Spray)	THE WASP-A-WAY ADVANTAGE
“Requires a Perfect Shot” At 0.02% Tetramethrin (Raid), only insects in the direct stream receive a lethal dose. A partial hit, a moving target, or an insect at the stream’s edge is a miss.	“Proximity Is Enough” At 0.200% Tetramethrin, every droplet in the spray cloud carries a lethal dose. Insects don’t need to be in the direct stream — contact with the spray cloud is sufficient.
“Range Disappears as the Can Empties” Most retail sprays perform at 10–12 feet by half-empty. A technician trusting a “20 feet” label with a partial can is closer to the nest than they think — with no way to know it.	“18+ Feet — Verified, Full Can” Multi-stage pressurization and batch testing at multiple production points verify consistent range performance from first spray to last. The standoff distance that works on job one works on job two with the same can.
“Can’t Go Indoors” Consumer sprays are outdoor use only — propellant flammability and EPA registration limitations exclude attics, crawl spaces, and mechanical rooms. The nest is inside. The spray legally can’t be.	“EPA Registered for Enclosed Spaces” WAW-1 carries indoor use registration covering attics, crawl spaces, mechanical rooms, and wall voids — the enclosed job site environments where nests are regularly built.

TARGET PEST	TYPICAL NEST LOCATION	ACTION	PERFORMANCE / WHY IT WORKS
Wasps & Hornets	Eaves, overhangs, attics	Contact Kill + Residual	Fast Knockdown: Tetramethrin (0.200%) penetrates the insect cuticle on contact for immediate kill. Residual chemistry in the treated nest kills insects returning after initial treatment.
Yellowjackets	Underground, wall voids, ground-level nests	Nest Entry Kill	Jet spray saturates nest entrance and interior. Treat in early morning or evening when the colony is fully inside and entrance activity is minimal for maximum contact coverage.
Aerial Nests (20+ ft)	Trees, utility poles, rooflines	Long-Range Jet	Batch-tested at multiple fill points to maintain 18+ feet of effective spray range throughout the entire can — not just at initial pressure. One product, full-can performance.
Scorpions	Ground level, under debris	Direct Contact Kill	Stand 3–4 feet away and thoroughly cover the insect. Confirm the scorpion is dead before removal. Petroleum distillate carrier provides rapid penetration and knockdown.

Surface & Environment Compatibility

SURFACE / ENVIRONMENT	STATUS & PROTOCOL
Vinyl, Painted & Plastic Surfaces	⚠️ TEST FIRST May stain or adversely affect surface. Test in an inconspicuous area and re-check in a few hours before applying where spray may contact these surfaces.
Asphalt Roofing Shingles	⚠️ AVOID IF POSSIBLE Staining may occur. Avoid direct application to shingles. Hose off any overspray promptly.
Desirable Plants & Foliage	⚠️ RINSE AFTER TREATMENT Hose off foliage of desirable plants that contact spray. Do not apply directly to blooming crops or weeds while bees are actively visiting.
Water / Aquatic Areas	🚫 DO NOT APPLY Extremely toxic to aquatic organisms including fish and aquatic invertebrates. Do not apply directly to water or allow runoff to reach drains, sewers, or water bodies.
Fish Aquariums & Pets	🚫 REMOVE BEFORE SPRAYING Remove pets and birds and cover fish aquariums before spraying. Turn aquarium systems off. Do not allow re-entry until spray has dried.

EPA Registration & Dielectric Rating:

Wasp-A-Way is EPA registered for indoor and outdoor use (EPA Reg. No. 1021-1649-6381), covering attics, crawl spaces, mechanical rooms, and wall voids — environments most consumer sprays are not registered for. The petroleum distillate carrier carries a 57,200V (57.2 KV) dielectric breakdown voltage tested by ASTM Method D-877, making it appropriate for use near energized electrical equipment. This is the highest verified dielectric rating in the commercial wasp spray category.

Directions for Wasp-A-Way (WAW-1)

1. Preparation

Step 1: Choose the Right Time.

Treat in the early morning or early evening when air temperature is cooler, most insects are inside the nest, and little activity is observed around the nest opening.
Spray only when the air is completely still. Wind will deflect the jet spray and reduce coverage on the nest.
Note: Do not make applications during rain.

Step 2: Assess the Nest Location.

Identify the nest opening before approaching. Plan your position so you are standing to the side — never directly under the nest.
For nests in wall voids or underground, locate the primary entrance point. For aerial nests (eaves, trees, rooflines), confirm the nest is within spray range before starting.
Pre-soak surrounding desirable plants with water if the nest is in vegetation to minimize chemical contact with foliage.

2. Application

Step 3: Position & Aim.

Stand at a safe distance from the nest. The jet spray reaches nests more than 20 feet above ground.
Hold the container upright at arm’s length and point the actuator directly at the nest. Do not invert the can.

Step 4: Spray the Nest Opening First.

Always treat the nest opening first. This immediately knocks down insects entering and exiting, preventing the colony from mobilizing during treatment.
Maintain a steady, directed stream — do not sweep rapidly. Allow the jet to penetrate the opening before moving to the nest body.

Step 5: Saturate the Entire Nest.

Continue spraying until the entire nest is saturated. Treated insects will fall from the nest and die.
Any insects returning to the nest after treatment will be killed by the residual action remaining in the treated nest.

3. Post-Treatment Protocol

Step 6: Wait 48 Hours.

SITUATION	ACTION
Nest Removal	WAIT 48 HOURS. Leave the treated nest undisturbed for a full 48 hours. This allows returning insects to contact the residual and be killed before the nest is removed.
Re-Entry (Treated Area)	WAIT UNTIL DRY. Do not allow adults, children, or pets to enter treated areas until sprays have dried completely.

Step 7: Clean Up.

Hose off foliage of any desirable plants that contacted spray.
After 48 hours, remove the nest using appropriate PPE (gloves, eye protection).
Do not water the treated area to the point of runoff. Do not allow runoff to reach drains, sewers, or water bodies.
