Frequently Asked Questions
Can I place these in my home office without them distracting me while I work?
Yes. Tuck tablets behind the desk, under the filing cabinet, and along the back edge of baseboards in the office. They are completely silent, odorless, and invisible once placed, so you can focus on deep work without noticing the treatment is even there.
Will this help me stop getting distracted by roaches during video calls?
Yes. Place tablets in the corners behind your desk, inside any cable management area, and along the back of the bookshelf. Within a week or two, the roaches that previously crawled across your wall during Zoom meetings will be eliminated and the background of your video will stay roach free.
I am a landlord, can I use this between tenants without scheduling an exterminator?
Yes. This is one of the most common professional use cases. Place tablets behind the refrigerator, under the stove, inside cabinet backs, and along baseboards during the turnover. The next tenant moves into a roach free unit without the cost or scheduling hassle of an exterminator service call.
How fast will I see results in my rental property between tenants?
Most landlords see a dramatic drop in roach activity within one to two weeks, with full colony elimination in the treated areas within a month. The tablets continue working for up to a year, so the unit stays protected through the next tenant's full lease term.
Can I use this in a Florida condo I only visit a few times a year?
Yes, and it is ideal for seasonal properties. Place tablets during your visit, leave them in place when you go home, and they will continue killing any new roach activity for up to a year. When you return next season, the unit will be protected without any new setup.
I run a small rental portfolio, is one bottle per unit enough?
Yes. A single 4oz bottle contains 96 tablets, which is enough to treat 12 or more rooms per unit. For a studio or one bedroom, one bottle will cover the entire unit several times over, including attic and garage if applicable.
Will this save me money compared to quarterly pest control contracts?
Most landlords report significant savings. A quarterly pest control contract for a single unit often costs more per year than two or three bottles of Harris Roach Tablets, with comparable or better results because the tablets target the colony rather than just the visible roaches.
Can I use this in a property I am preparing to sell or show?
Yes. Place tablets two to four weeks before listing the property. By the time showings begin, the roach activity will be eliminated, the home will smell neutral, and the listing photos and walkthroughs will not include any cockroach sightings, which significantly improves buyer confidence.
As a real estate agent, can I recommend this to my seller clients?
Yes. The tablet form is renter friendly, does not require professional application, and the EPA registration gives sellers confidence the treatment is safe. Many agents keep a bottle on hand for quick pre listing treatments that cost a fraction of professional services.
I am an ER nurse working long shifts, will this stay effective while I am away?
Yes. The tablets are passive and continue working 24/7 with no attention required. Place them once on a day off, and they will kill roaches every day and night you are at the hospital, with no maintenance, no reapplication, and no timer to remember.
Will this help me focus on studying without the anxiety of seeing roaches at my desk?
Yes. Tuck tablets behind the desk, under the bed if it is in the same room, and along the baseboard behind your bookshelf. Within a week or two the roach sightings will stop, and you can maintain your study focus without the constant low grade distraction of pest activity.
I have a home based business, will clients notice the roach treatment during meetings?
No. The tablets are invisible once placed in crevices, have no odor, and do not require any visible equipment in the room. Clients will simply notice a clean, pest free environment without ever seeing the product doing the work.
How does this compare to monthly pest control service for a busy professional?
Monthly service requires you to be home for the technician, costs hundreds per year per unit, and often uses spray products with strong odors. Harris Roach Tablets require one placement, cost a fraction of the annual service fee, and continue working for up to a year without further attention.
Can I use this in a basement level NYC apartment during the summer roach season?
Yes, and basement NYC apartments are a primary use case. Place tablets behind the radiator, under the kitchen sink, along the baseboards where the wall meets the floor, and inside any shared wall void. The tablets handle the summer American roach surge without requiring landlord access for spray treatments.
Will this help me pass a rental inspection if my landlord does a pest check?
Yes. Place tablets in advance, and the roach activity will be eliminated before the inspection. Because the tablets are hidden in crevices, they are not visible during the inspection, and the inspector will find no live roach activity in the treated areas.
Can I delegate the placement to my house cleaner or family member?
Yes. The placement is simple: tablets go behind appliances, under sinks, and in cabinet backs. You can write out the locations on a list for anyone helping with the setup, and the treatment does not require any special equipment, training, or protective gear.
How do I place Harris Roach Tablets for the best results?
Place tablets in the spots roaches travel: behind the refrigerator, under the kitchen sink, inside cabinet backs, along baseboard cracks, behind the stove, under the dishwasher, and in any wall void or floor gap. Use 6 to 8 tablets per room for typical German roach infestations, and 8 to 12 per room for heavy American roach or water bug activity. Replace consumed tablets monthly until the gnaw marks stop appearing.
Can I crush the tablets and use them as powder in cracks?
Yes. Crushing tablets into a fine powder is one of the most effective ways to treat narrow crevices, door hinge gaps, and floorboard cracks where roaches disappear. Sprinkle the powder very lightly so roaches walk through it unknowingly, and they will carry the active ingredient back to the nest for the secondary kill effect.
Can I mix crushed tablets with peanut butter as a stronger bait?
Yes. A common DIY method is to crush a tablet, mix the powder with a small amount of peanut butter, and place the mixture inside water bottle caps taped to DIY roach traps. The peanut butter adds an extra attractant layer on top of the built in lure, and the boric acid remains the killing agent.
Do these work on German roaches and American roaches equally?
Yes. The 40 percent boric acid formula with food based lure is effective on German cockroaches, American cockroaches, Palmetto bugs (which are American cockroaches), water bugs, and other large outdoor roach species. Placement density and frequency may vary by species, but the active kill mechanism is the same.
Will these tablets work in a humid environment like a bathroom or basement?
Yes. The tablets remain effective in humid conditions as long as they are not fully submerged. Place them on the back of the toilet, under the sink inside the cabinet, and along the tub baseboard. In basements, place them on shelves, in corners, and inside the HVAC drip pan where condensate collects. Tablets that get soaked should be replaced.
What is included in the 4oz bottle?
Each 4oz bottle contains 96 solid boric acid roach tablets with built in food lure, plus a small amount of tablet powder inside the bottle. A 6oz bottle is available for larger treatments covering more rooms. No additional equipment, bait stations, or applicators are required; the tablets are placed directly in the target locations.
Do the tablets expire or lose potency over time?
No. The tablets have no expiration date when stored dry, and many users report that tablets left out for a full year were still killing roaches at the end of that period. The active ingredient remains chemically stable, and the residual effectiveness in placement locations lasts up to 12 months.
Is boric acid safe to use in a home with a septic system?
Yes. Boric acid at the residential pest control concentration does not disrupt septic system bacterial balance. The amount that could potentially reach the septic system from a few placed tablets is negligible, and boric acid is commonly used in household products that flow into septic systems without issue.
What is the difference between roach tablets, gel bait, and boric acid powder?
Roach tablets are solid boric acid with a built in attractant, designed for hidden placement in cracks and crevices. Gel bait is a syringe applied gel that roaches feed on, also placed in hidden spots, but it is more visible during application and dries out faster. Boric acid powder is loose dust that can be spread in voids but creates mess, tracks on pet paws, and is harder to remove before guests or children visit. Tablets offer the best balance of effectiveness, cleanliness, and removability.
