Use Pesticides Safely A pesticide is any substance, natural or manufactured, used to destroy pests. All pesticides sold in stores display important information on their labels, such as ingredients, directions for use, hazards and precautionary measures. Read the entire pesticide label. Always apply the pesticide according to the directions. Make sure it is intended for the target pests.
Caution is the safest.
Be aware that certain pets such as birds or fish may be very sensitive to some pesticides. Most live outdoors, entering buildings in search of food or water. Some species, such as pharaoh or ghost ants, establish indoor colonies. Proper treatment depends on the type of ant. Bait stations work on some species.
