If you need to spray pesticide inside your home to get rid of ticks, use a pyrethrin-derived spray, which will break down quickly and be less of a health risk for pets and your family, according to the U.S. Army. Pesticides may be applied to cracks and crevices as well as to surfaces.
If you prefer not to spray pesticides inside your home, you may add a few drops of certain essential oils to a spray bottle filled with water. Rose geranium, palmarosa and opopanax oils will repel ticks and keep them away from the areas where they are sprayed, according to "The Encyclopedia of Natural Pet Care."
Keep pets and children away from areas where you have just sprayed.
Pesticides will are labeled to the environments they treat most effectively.
The scents of essential oils may interfere with a dog's ability to distinguish other scents, so they could impede a hunting dog's ability in the field.
