Harris Flea and Tick Killer is labeled for indoor and outdoor use. Before using it indoors, cover any food and food handling equipment in the area. It is also helpful to remove items from the floor and vacuum the area prior to treatment. Lastly, you should remove pet bedding and wash it thoroughly or discard it. Return the bedding only after the spray has dried.
- Start by removing the cap and screwing the sprayer onto the bottle.
- Turn the spray nozzle to the “on” position.
- Hold the container upright and hold the spray nozzle approximately 12 inches from the surface you want to treat.
- Squeeze the trigger and spray until the surface is slightly moist. You don’t want to spray too much so that the liquid drips and runs off.
- Continue to spray in areas where fleas and ticks live or may be hiding. Specific areas may include: rugs and carpets where pets spend time, around doors and windows where fleas and ticks may enter the house, under refrigerators, cabinets, sinks, and stoves, around the outside foundation of your home, and on bushes, grass, or weeds that are infested with fleas or ticks.
- Harris Flea and Tick Killer will kill pests when it has dried and will continue to kill them for several weeks to months, depending on the porosity of the surface.
- Do not allow people or pets to contact the spray until after it has dried.
- You can reapply after a few weeks, if needed.
