Harris makes EPA-registered pest control products and industrial cleaning solutions that work. Their 99% boric acid roach killer and 30% concentrated vinegar are the two products contractors actually stock on their trucks.
Professional-Grade Pest Control That Actually Works
Harris’s roach killer contains 99.0% boric acid with 1.0% food-grade attractant lure. That lure makes all the difference. Roaches come out from hiding spots to investigate, walk through the powder, and die within 72 hours of contact.
The powder formulation beats tablets for coverage area. You can dust behind appliances, under sinks, and into wall voids where roaches actually travel. The non-caking formula remains free-flowing and effective for weeks if kept dry. No clumping means consistent application through the puff bottle.

EPA-registered for residential use with people and pets present — but keep it in cracks and crevices where kids and animals can’t reach. The registration matters for commercial applications where compliance documentation gets checked.
Industrial-Strength Cleaning Without the Chemical Soup
Harris 30% Vinegar is six times more powerful than standard vinegar. At that concentration, it’s not salad dressing — it’s an industrial cleaner that handles rust, hard water stains, and pH adjustment for agricultural operations.
Its lack of dyes and chemicals means you’re not adding more problems while solving the first one. Common use cases among professionals include outdoor cleaning of patios and driveways, agricultural applications, and industrial cleaning.
The dilution flexibility matters. You can run it straight for heavy deposits or dilute it down for routine maintenance. Its high concentration requiring careful handling and dilution to avoid skin or material damage — this isn’t homeowner-grade cleaner. Wear gloves. Work in ventilated areas.
Why Contractors Choose Harris Over Alternatives
Powder with lure provides better coverage for large areas and attracts roaches directly, while boric acid is generally more stable than many liquid pesticides. Liquid baits work but need constant replacement. Gel baits dry out. Harris powder keeps working as long as it stays dry.
The 30% vinegar outperforms standard cleaners without the bleach, ammonia, or mystery chemicals. In Montana’s agricultural operations — from grain elevators to food processing — that chemical-free profile matters for compliance and worker safety.
Contractors appreciate its versatility across multiple job types. One product handles concrete cleaning, equipment degreasing, and soil pH adjustment. Less truck inventory, more capability.
Frequently Asked Questions
Q: How long does the boric acid powder remain effective after application?
The powder provides long-lasting residual control as long as it remains dry and undisturbed. In protected areas like wall voids or under appliances, it can remain effective for months. Reapply after cleaning or if the powder gets wet.
Q: Can I use 30% vinegar on all surfaces?
No. It is not recommended for use on delicate surfaces or materials that could be harmed by strong acids. Test on an inconspicuous area first. Safe for concrete, glass, and tile when used properly.
Q: What’s the actual dilution ratio for the 30% vinegar?
Depends on the job. For general cleaning, start with 1:10 (vinegar:water). For heavy deposits, use it straight. Agricultural pH adjustment varies by soil test results — no universal ratio exists.
Q: Where should I apply the roach powder for best results?
Common application areas include behind and under appliances, under sinks and along plumbing/drains, cracks and crevices in walls, floors, and cabinetry, along baseboards and window/door frames, wall voids and dryer vents, and inside pipe penetrations and cabinets. Focus on travel paths, not open areas.
