Call (613) 743-8074 Compare the common domestic flea, the less-common dog flea and the environmental larval stage.

| Dog Flea | About 2–4 mm | Very similar to the cat flea; head shape differs under magnification | Primarily dogs and wild canids | Year-round where established |
| Flea Larva | About 2–5 mm | Pale, legless and worm-like with fine hairs | Carpet edges, cracks, pet bedding and protected debris | Develops off the host in the environment |
