What causes fleas to appear in a house without animals?
Flea populations can originate in a residence even when no pet is present because the insects develop from eggs and larvae that survive in the indoor environment. Adult fleas lay eggs on a host, but a significant portion of eggs fall off onto carpets, bedding, or cracks in flooring.. Date latest changes:

Is it safe to shower after a tick bite: myths and realities?
Ticks attach to the host’s skin by inserting their hypostome, a barbed feeding organ, after locating a suitable site through heat and carbon‑dioxide cues. Once anchored, they secrete cement‑like proteins that harden to keep the mouthparts stable for the duration of the blood meal.. Date latest changes:
How quickly do symptoms appear after a tick bite in a human?
Ticks develop through four distinct stages: egg, larva, nymph, and adult. Each stage, except the egg, must obtain a blood meal to molt to the next phase. Eggs hatch into six‑legged larvae that seek small hosts such as rodents or birds. After engorgement, larvae drop off, molt into eight‑legged nymphs, which then locate larger hosts, including humans..
