Household fleas: where do they come from and how to get rid of them?
Fleas develop through four distinct stages: egg, larva, pupa, and adult. Adult females lay 20‑50 eggs each day on a host or in the surrounding environment. Eggs are smooth, white, and hatch within 2‑5 days under warm, humid conditions; they fall off the animal and accumulate in carpets, bedding, or cracks in flooring.. Date latest changes:
What happens when a tick remains on the skin?
Ticks attach through a specialized sequence of actions that secure the parasite to the host’s epidermis. The process begins when a questing tick detects heat, carbon dioxide, or movement and moves onto the skin surface. The mouthparts, composed of the chelicerae and the hypostome, then penetrate the outer skin layers.. Date latest changes:

Are cat fleas transmitted to humans?
Cat fleas (Ctenocephalides felis) are small, wing‑less insects measuring 1–3 mm in length. Their laterally compressed bodies enable movement through a host’s fur. Adult fleas possess powerful hind legs that produce rapid jumps up to 150 times their body length.. Date latest changes:
When are bedbugs most active: day or night?
Bed bugs exhibit heightened activity in low‑light environments because darkness offers several physiological and ecological advantages. Reduced exposure to visual predators allows the insects to move between hosts and hiding places with minimal detection.. Date latest changes:
How quickly do fleas reproduce on dogs?
Flea development proceeds through egg, larva, pupa and adult stages, each governed by temperature and humidity. Eggs hatch within 24–48 hours when ambient conditions exceed 15 °C (59 °F). Larvae require a moist environment, preferably 70–80 % relative humidity, to feed on organic debris and mature in 5–11 days.. Date latest changes:
How to get floor fleas out of an apartment?
