Tapeworms are intestinal parasites that are most often found in outdoor pets. Your pet can get them from the waste of another animal that was carrying the worms. Fleas in your yard can also ingest tapeworm eggs and pass them along to your pet. If you spot areas of tapeworms living in your yard, you can use special chemicals to eliminate them, but you also must keep your pet away from the area. Once the worms are removed you should maintain your yard to prevent the problem from recurring.
Locate the tapeworms in your yard. Remove all of your pet's waste from your yard using a scooper. Check your pet for fleas and contact your vet for the appropriate deworming medicine.
Purchase a worm-killing chemical--an insecticide or fungicide--from your local home and garden retailer. Make sure the chemicals will not harm your grass. Spray on the worm-infested area as directed on the label.
Wait 24 hours, or longer if directed on the insecticide label, before checking the area again. Apply more of the chemicals if necessary until you can see that all of the tapeworms are dead. Keep your pets away from the area during this time.
Put on rubber gloves. Use a small shovel to remove all of the dead tapeworms and place them in a sturdy trash bag.
Continue maintaining your yard once you rid it of the tapeworms. Clean up waste from your yard and consider fencing in any areas where wild animals may try to enter your yard. Continue giving your pet dewormer periodically as instructed by your vet.
