Natural Habitat

Intestines of host animals (dogs, cats, wildlife); dried segments are often found on pet bedding, furniture, carpet, or around a pet's rear end.

Diet & Feeding

Parasitic; absorbs digested nutrients directly from the host animal's intestine.

Behavior Patterns

Moist segments crawl out of the host's anus or pass in feces. As they dry, they contract and harden into seed-like structures, releasing eggs into the environment.

Risks & Benefits

Risks: Indicates a tapeworm infection in domestic pets or livestock, which can cause weight loss, anal irritation, or nutritional deficiency. Humans (especially children) can occasionally ingest infected fleas resulting in accidental infection. Benefits: None.
