Harris makes ready-to-use pest control products and industrial-strength cleaning solutions that contractors rely on for measurable results. Not the flashy stuff you see on TV commercials — these are workhorse products that solve real problems on job sites and in commercial buildings.
EPA-Registered Pest Control That Actually Works
The Harris Boric Acid Roach Killer delivers 99% boric acid concentration in a 16 oz ready-to-use powder. That’s professional-grade pest control with an EPA registration number to back it up.
What makes this formulation work is the included food-grade attractant lure — it actually draws insects out of hiding instead of hoping they stumble across the treatment. The powder kills insects within 72 hours of contact, and here’s the critical part: it provides long-lasting residual control as long as the powder remains dry and undisturbed.
The application method matters. Harris includes a pro-applicator tip for precision dusting, because dumping piles of powder everywhere doesn’t work — insects are less likely to walk through large piles of powder. You need a light, even dusting in the right locations.
Coverage Areas and Application
| Target Area | Application Method |
|---|---|
| Behind and under appliances | Light dusting with applicator tip |
| Under sinks and along plumbing/drains | Thin layer application |
| Cracks and crevices in walls, floors, and cabinetry | Precision tip targeting |
| Wall voids and dryer vents | Dust application |
| Inside pipe penetrations | Targeted dusting |
The formula targets cockroaches, palmetto bugs, water bugs, silverfish, and other crawling insects. It’s EPA-registered for residential use with people and pets present, but you still need to keep treated areas out of reach of children and pets.
Industrial-Strength Vinegar That Outperforms Standard Cleaners
Harris 30% Vinegar delivers 6x the strength of standard 5% white vinegar in a 1-gallon concentrate. This isn’t grocery store vinegar — it’s 30% acetic acid concentration designed for heavy-duty cleaning tasks.
The concentrate is certified for organic use, which matters more than you’d think in Montana where clients increasingly want environmentally responsible solutions. No dyes, bleach, ammonia, or fillers — just concentrated cleaning power.
Dilution and Applications
| Application | Surface Types |
|---|---|
| Rust and hard-water buildup removal | Metal, porcelain, tile |
| Stubborn grime and stain removal | Patios, driveways, and decks |
| Carpet cleaning | Commercial and residential carpets |
| Kitchen and bathroom surfaces | Multi-surface compatibility |
| Boat cleaning | Fiberglass, metal, vinyl |
The product is safe for indoor and outdoor use when diluted. For Montana’s hard water challenges — especially in areas with high mineral content — this concentration level cuts through deposits that standard cleaners can’t touch.
Additional uses include laundry deodorizer, pet area cleaning, garbage can sanitizing, and even horticultural use and natural weed and grass killer when diluted.
The industrial concentration means you’re hauling less product to achieve better results. A single gallon can handle multiple job sites when properly diluted, which beats buying cases of pre-diluted cleaners that barely work on Montana’s mineral deposits.
