What do household fleas look like and how can you get rid of them? - in detail
Household fleas are small, wing‑less insects measuring 1.5–3 mm in length. Their bodies are laterally compressed, giving a jumping flea a “C” shape when at rest. The exoskeleton appears dark brown to reddish‑brown; after feeding, the abdomen becomes distended and lighter in color. Fleas possess long hind legs adapted for powerful leaps, allowing them to move several centimeters upward with each jump. Antennae are short, segmented, and hidden beneath the head. Eyes are simple and usually not visible without magnification. Eggs are oval, about 0.5 mm, and are laid in the environment rather than on the host.
Effective eradication requires a multi‑stage approach:
• Inspection – Use a fine‑toothed comb on pets and a bright flashlight on carpets and bedding to locate adults, larvae, and eggs.
• Treatment of animals – Apply veterinarian‑approved topical or oral insecticides; repeat according to product instructions to cover the flea life cycle.
• Environmental control – Vacuum carpets, rugs, and upholstery daily; discard vacuum bags or empty canisters immediately.
• Washable fabrics – Launder bedding, curtains, and pet blankets in hot water (≥ 60 °C) and tumble‑dry on high heat for at least 30 minutes.
• Insecticide application – Use a residual spray or fogger labeled for indoor flea control, focusing on cracks, baseboards, and pet resting areas; follow safety guidelines.
• Biological agents – Introduce nematodes (e.g., Steinernema spp.) into soil or outdoor areas where fleas breed; these parasites attack flea larvae.
• Monitoring – Place sticky traps in strategic locations to assess ongoing activity; replace traps weekly.
Completing each step within a 2‑ to 4‑week window interrupts the flea’s development from egg to adult, preventing reinfestation. Regular grooming of pets and routine cleaning of the home sustain a flea‑free environment.
