Hookworm nematodes (Ancylostoma braziliense, Uncinaria stenocephala, Ancylostoma caninum) commonly infect dogs and cats. A zoonotic parasite, the worm can also infect humans. Specific hookworms, Ancylostoma duodenale or Necator americanus, occur only in humans. All hookworm eggs require soil to complete their life cycle. To eradicate hookworms from an animal or human, the soil in the surrounding environment must also undergo treatment while the host receives medical attention. A successful treatment regime involves maintaining sanitary soil conditions by promptly removing fecal matter and spraying to kill the larvae.
Pick up all fecal matter from the soil, using a shovel or animal waste scooper. Dispose of the fecal matter in a plastic bag.
Spray the soil every other day over the course of at least four weeks, using salt brine and water. Mix 1 1/2 lbs. of salt with 1 gallon of water. Spray approximately 1 pint of water and salt over every 1 square foot of soil, using a garden sprayer.
Spray 3 cups of bleach mixed in 1 gallon of water across the soil's surface, using a garden sprayer. Use a garden sprayer to lightly spray the soil. Spray it daily after removing any fecal matter. Avoid getting the bleach on foliage or grass because it will quickly kill plant life.
Sprinkle borax over the top of the soil lightly every day. Coat the soil so there is a slightly white appearance after spraying with the salt and water solution.
