Most ticks of importance include the Brown Dog Tick, American Dog Tick, Lone Star Tick, or the Black-Legged Tick (Deer Tick).
On the exterior/perimeter, make a perimeter treatment, concentrating on areas where pets rest or run. Treat likely harborage areas like along paths, tall grass and other vegetation. For best results, treat the entire area where ticks could be present. Begin treating in the spring. Ticks may be re-introduced from surrounding areas by host animals. Continue treating until frost to control both larvae and adult ticks.
For indoor use, most labels will direct you to apply to areas where pests hide. These areas include baseboards, corners, storage areas, closets, around water pipes, doors and windows, attics and eaves, behind and under refrigerators, cabinets, sinks, furnaces, stoves, the underside of shelves, drawers and similar areas. Pay close attention to cracks and crevices.
