Fleas are one of the most persistent household pests in the UK, and London’s dense housing, warm indoor environments, and high pet ownership make infestations increasingly common. Even homes without pets can develop flea problems, especially in converted flats or older properties where fleas may linger in carpets, floorboards, or voids.
Fleas feed on blood — usually from cats, dogs, or rodents — but they will bite humans when food sources are limited. Their bites can cause itching, allergic reactions, and secondary skin infections, making fast action essential.
Fleas can enter a property through:
Once inside, fleas reproduce rapidly. A single female can lay up to 50 eggs per day, meaning a small problem can escalate quickly.
Look for:
If you’re noticing bites but don’t have pets, fleas may be coming from rodents in the building — a common issue in London’s older properties.
Fleas have a complex life cycle with four stages: egg, larva, pupa, and adult. The pupal stage is the biggest challenge — pupae can remain dormant for months, protected inside a tough cocoon that resists most DIY treatments.
This is why infestations often seem to “come back” even after cleaning or spraying.
Use vet‑approved flea treatments, not supermarket spot‑ons. Flea collars and cheap sprays rarely work.
Wash bedding, throws, pet blankets, and cushion covers at 60°C. Dry on high heat to kill eggs and larvae.
Focus on:
Empty the vacuum outside immediately — flea eggs can hatch inside the bag.
High heat kills larvae and helps trigger dormant pupae to emerge, making them vulnerable to treatment.
DIY sprays rarely penetrate deep enough. Professional treatments target:
Multiple treatments may be required depending on the severity.
If you don’t have pets, fleas may be coming from rodents. Treating the fleas without addressing the rodent source will only provide temporary relief.
Professional pest control technicians use insecticides that:
They also identify the root cause — whether it’s pets, rodents, or environmental conditions — ensuring long‑term elimination.
Fleas thrive in warm, dusty environments — keeping your home clean and well‑maintained is the best defence.
