How do earth fleas differ from animal fleas?
Fleas are small, wing‑less insects belonging to the order Siphonaptera. They possess laterally compressed bodies, powerful jumping legs, and a siphon‑shaped mouthpart adapted for piercing skin and sucking blood. Adult fleas measure 1–4 mm in length, are ectoparasites of mammals and birds, and complete their life cycle through egg, larva, pupa, and adult stages.. Date latest changes:
What to do if a tick bit you but the tick is missing?
A tick bite that cannot be retrieved still poses a risk of infection. The first indicator is a red spot at the bite site. Look for a small, circular rash that expands outward, often forming a “bull’s‑eye” pattern. If the skin around the bite becomes warm, swollen, or tender, these are early local reactions..
