In this expert 2025 guide, I’ll teach you how to prevent infestations, recognize early signs, treat safely under veterinary guidance, and avoid re-infestation.

1️⃣ Why Parasite Prevention Matters

• Preventing parasites is easier, safer & more affordable than treating infestations :contentReference[oaicite:3]{index=3}.
• Parasites can transmit disease, cause anaemia, skin irritation, digestive upset and even death if left unchecked.

2️⃣ Maintain a Clean Habitat 🔄

• Spot-clean daily; deep-clean weekly using pet‑safe disinfectants :contentReference[oaicite:4]{index=4}.

3️⃣ Feed High‑Quality Diet for Healthy Immunity

5️⃣ Common External Parasites & Treatment

• Mites & Lice

• Use vet-prescribed safe topical (e.g. imidacloprid, selamectin) for species like rabbits, ferrets, guinea pigs :contentReference[oaicite:12]{index=12}.
• Treat household surfaces and other pets too :contentReference[oaicite:13]{index=13}.

6️⃣ Common Internal Parasites & Treatment

• Worms

• Pinworms, tapeworms, heartworms (in ferrets) may show GI upset or weight loss :contentReference[oaicite:15]{index=15}.

• Treat only after proper diagnosis and follow-write vet dosage exactly.
• Treat all in-contact animals simultaneously—even asymptomatic ones :contentReference[oaicite:22]{index=22}.

8️⃣ Preventing Re-Infestation

• Redouble cleaning throughout treatment—wash fabric, sanitize hard surfaces, vacuum carpets.
