FAQ

How Do I Use This Product Safely And Effectively?

This product is a concentrate, so you need to dilute it with water and apply with a tank sprayer according to the label directions; one 32 fl. oz. bottle can make up to four gallons. For perimeter work, treat a band around the foundation and entry points, and for indoor use apply only to non-porous surfaces and allow it to dry before re-entering the area.

Wear gloves and eye protection while mixing and spraying, keep pets and children away during application and drying, and always follow label instructions for the correct mix rates and safety precautions.

Will It Harm My Pets Or Family?

When used exactly as directed the product is commonly reported to be safe around pets and people once the treated area is dry, but it is still a pesticide so you should be cautious. Keep pets and children out of the treatment area until the spray has fully dried, store the concentrate locked away and never apply where food is prepared or where toys and pet bowls are left out.

If you have specific concerns about allergies or sensitivities, check the label for active ingredients and precautionary statements or consult your veterinarian for tailored advice.

How Long Does Protection Last And When Should I Reapply?

The maker indicates up to 12 months of protection on non-porous indoor surfaces for ants, roaches and spiders, but outdoor longevity varies with weather, traffic and how porous the treated surface is. Heavy rain, high-traffic areas or persistent infestations usually mean you should reapply sooner, and many people find a seasonal or quarterly follow-up keeps populations down; basements prone to moisture often need more frequent touch-ups. If you prefer a ready-made option rather than mixing concentrate, consider the [Prime] Ortho Home Defense Mosquito Control Station Kit $31.43 + Free S&H at Amazon, though the concentrate version on Amazon is also competitively priced at $18.99 and stretches farther.
