Fleas are parasites that live off of the blood of animals and humans. They live outdoors, but migrate quickly and can invade the home if not eradicated. Controlling the spread of fleas is essential to protect the health of humans and pets. There are ways to kill flea colonies in the yard using commonly available flea control treatments. You should treat fleas as soon as you see them in the yard to prevent them from reproducing.
Things You'll Need
- White tube socks
- Garden sprayer
Determine if the yard is infected by fleas. Put on white, tube socks that come up to the knee. Walk across the entire surface of the yard wearing only the socks. Look at the socks for small black specks that are moving, which indicates fleas. Take off the socks before re-entering the home.
Buy an insecticidal treatment that is labeled as effective for killing fleas. According to the University of Kentucky College of Agriculture, the most-effective insecticides contain methoprene, pyriproxyfen and permethrin. These chemicals kill both adult fleas, as well as the eggs and larvae.
Open the top of a garden sprayer by grasping the top handle and turning it counterclockwise. Pour the insecticide into the garden sprayer, place the top back on it and secure it by turning the handle clockwise. Hold the garden sprayer tank handle in one hand while pointing the spray nozzle toward the ground. Depress the sprayer trigger to dispense the insecticide.
Spray areas of the yard where pets spend most of their time, including kennels, running areas and sleeping areas. Also spray any other areas of the yard where fleas inhabit.
Allow the insecticide to dry thoroughly before walking on it or allowing pets access to it.
