Bedbugs (Cimex spp.) are small, wing‑less insects that attach to hosts for short periods while seeking a blood meal. Their ability to move between locations depends on external carriers, including vertebrate animals that may inadvertently transport them.. Date latest changes:
Why do flea drops sometimes fail to work on cats?
Active ingredients in topical flea treatments for cats target the nervous system of adult fleas, disrupt development, or inhibit chitin synthesis. Imidacloprid binds to nicotinic acetylcholine receptors, causing paralysis and death. Selamectin interferes with glutamate‑gated chloride channels, leading to paralysis of larvae and adult fleas..

Bedbugs (Cimex lectularius) develop through five distinct stages: egg, first‑instar nymph, second‑instar nymph, third‑instar nymph, fourth‑instar nymph, fifth‑instar nymph, and adult. Each stage, except the egg, requires a blood meal to progress to the next instar.. Date latest changes:
How can you detect a tick on the skin, and what signals indicate its presence?
Early identification of attached ticks dramatically lowers the probability of pathogen transmission. Most tick‑borne microbes require several hours of feeding before they move from the arthropod’s salivary glands into the host’s bloodstream.. Date latest changes:
Can dichlorvos safely and effectively eradicate bedbugs?
Bedbugs develop through five nymphal instars before reaching maturity. Each stage lasts 5–10 days at 22–30 °C, with a blood meal required for molting. The cycle begins when a fertilized female deposits 1–5 mm eggs in protected crevices. Eggs hatch in 6–10 days, releasing first‑instar nymphs that cannot feed until they mature.. Date latest changes:
How should Inspector tablets be correctly administered to dogs for tick control?
Inspector tablets for canine tick control contain two primary pharmacological agents. The first, afoxolaner, belongs to the isoxazoline class and acts as a ligand‑gated chloride channel antagonist in arthropod nervous systems. By disrupting GABA‑gated chloride influx, it induces hyperexcitation, paralysis, and death of attached and feeding ticks.. Date latest changes:
