Coccidia is a parasite that attacks the intestines of animals and humans. It often is a problem with dogs and cats. Since it is transmitted through fecal matter, a yard can become a breeding ground for coccidia. Removing fecal matter from the yard and then preventing your animals from using it for at least 30 days is recommended. If this is not possible, help treat and prevent reinfection by incorporating a few techniques that are known to kill coccidia and limit its spread.

Dogs can pick up coccidia from the fecal matter in the yard.

Step 1

Wear rubber gloves and discard animal feces in your yard in sealed plastic bags.

Step 2

Clean pooper scoopers and yard tools with a mixture made from one part ammonia and nine parts water. Leave the ammonia on the tools for at least 20 minutes before rinsing them off.

Step 3

Spray the yard with the ammonia solution, paying special attention to where the feces were located. After 20 to 30 minutes, water the yard with 1 to 2 inches of water to flush the soil of ammonia so your grass is not harmed.

Step 4

Clean yard debris, such as wood and junk piles, to create an environment less conducive to rodents and bugs. They can pick up the disease, leave affected fecal matter and reinfect your animals with coccidia.
