How to Clean a House of a Pinworm Infestation

Pinworm infections are highly contagious. They can easily be transmitted among household members. Tiny pinworm eggs that are accidently transferred to the hands, onto clothing or around the house can reinfect household members.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Reinfestation can occur through inadvertently swallowing pinworm eggs or through inhaling eggs that are in the air. According to the Center for Disease Control, pinworm eggs survive away from the body for two to three weeks. Controlling a pinworm infection involves taking medication prescribed by a physician to kill the pinworms and preventing reinfection. Practicing regular hand washing and housecleaning can significantly reduce the likelihood of pinworm reinfestation.

Shower each morning to remove pinworm eggs from the body. A shower is preferable to a bath, because there is a possibility of pinworm contamination from eggs floating in the bath water. Clean the shower thoroughly after use.
