Fleas in a New Home: Previous Pet Owners and Dormant Eggs

Moving into a new flat or house and suddenly being bitten around the ankles is a classic flea story.

The short answer

If a previous occupant had pets, flea pupae can sit dormant in carpets and cracks for months and hatch when your footsteps and warmth arrive. Clean thoroughly before settling in: vacuum floors and edges, wash soft furnishings, and consider a professional flea treatment before moving furniture in. Keep following up for a few weeks, as hatching continues.

Why it happens

• Dormant pupae wait for vibration and warmth.
• Empty homes can hide flea populations for months.
• Carpets, cracks and skirting give cover.

Before you move in

1. Ask about previous pets.
2. Vacuum and clean all floors and edges.
3. Book professional flea treatment if there was a pet.
4. Treat before moving furniture and bedding in.

After moving in

• Vacuum daily at first.
• Hot-wash fabrics.
• Treat your own pets as advised by the vet.
• Watch for bites and fleas and call for follow-up if needed.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
