How long does it last?

I try to reapply every month. But it has gone as long as two months and still no ants cross the barrier where I sprayed. As long as no dirt gets on the surface or it doesn’t get rubbed off it seems to last.

How long does it last?

I first applied it at least 6 months ago and it is still effective.

Is it safe to apply AntCant while indoors?

Hi Leon, AntCant comes as a liquid in a trigger sprayer bottle. The carrier solvent is flammable so it should not be used or applied near any type of flame/ignition source. Immediately upon application, the flammable carrier solvent evaporates rapidly, within 5 minutes. Due to its rapid evaporation, during the evaporative process, the carrier solvent has a strong odor. We strongly suggest that AntCant be applied outdoors or in a well ventilated space. If you plan to apply indoors, we suggest removing the trigger sprayer head from the bottle and using a small paint brush to apply to a localized area. Thanks for your support. Please let us know if you have additional questions.
