🐾 Creepy-Crawlies Part 3: Fleas!
Last in our external parasite series: fleas—tiny, fast, and always hungry.
Flea Facts
All adult fleas are blood feeders. They survive and reproduce by piercing the skin and sucking blood.
Fleas are zoonotic. They don’t care whose blood they drink—pets, wildlife, or even people.
How fleas spread: Through contact with other animals or contaminated environments like tall grass, kennels, carpets, or pet bedding.
Life Cycle:
🐣 Eggs (1-12days) – don’t stick to fur, they fall everywhere
🐛 Larvae (5-20days) – feed on “flea dirt” and free moving
🧵 Pupae – strong, protective cocoons AND the most resistant stage to treat.
🦗 Adults (A few days to a few weeks depending on host access) – jump on a host and start feeding
➡️ Entire cycle can finish in 2–3 weeks in ideal conditions.
Clinical Signs of Fleas
Extreme itching or scratching
Flea dirt – tiny black pepper-like specks
Visible fleas – small, dark, fast-moving insects
Red bumps or scabs, especially on the belly or lower back
Hair loss from excessive scratching or grooming
Pale gums – a sign of anaemia in severe infestations, especially in young or small pets
Diagnosis
Call your family veterinarian and describe your pet’s symptoms. They may:
Use a fine-toothed flea comb
Examine debris under a microscope to confirm species and life stage
This helps determine the best course of treatment and prevents using the wrong product on the wrong pet.
Treatment
On Your Pet
✅ Flea comb
Comb out as many live fleas as possible before bathing. Do this in a non-carpeted area (garage, bathroom, patio). Dip the comb in soapy water between passes.
✅ Bathing
With your vet’s guidance, use a mild or flea-specific shampoo. This kills the fleas currently on your pet—but remember, without environmental cleanup, fleas will come back.
✅ Flea preventatives
Your veterinarian may recommend topical or oral preventatives. Always tell them about all pets in the household—some products safe for dogs are highly toxic to cats.
Environmental Cleaning: The Key to Success
Fleas spend more than 90% of their life cycle OFF the animal, so treating the environment is essential.
✅ Wash all bedding your pet uses in hot soapy water; dry on the highest heat safe for the fabric.
✅ Vacuum thoroughly and frequently
Carpets, rugs, furniture, baseboards—anywhere eggs and larvae could be hiding. Empty the vacuum canister immediately.
✅ Treat outdoor areas
If your pet uses an outdoor run, catio, or doghouse, you can use an appropriate pest-control product if needed.
That wraps up our parasite triad! 👏
