Fleas in a New Home or Rental: What to Do First

You collect the keys, carry the boxes in, and by the second evening your ankles are covered in bites. It is a surprisingly common story. Fleas can lie dormant in carpets of an empty property, and a new household walking in is exactly the signal they have been waiting for.

If this is happening to you, a calm order of steps will save time and avoid arguments. Here is what to do first.

Step one: make sure it really is fleas

Itchy bites do not always mean fleas. Look for small, red spots clustered around the ankles and lower legs, and check carpets with the white sock test: walk slowly across a carpeted room in white socks and look for tiny dark insects that jump.

Dark specks that turn reddish-brown when dabbed with damp white paper are flea dirt. Take clear photos. If the bites are mainly on arms and shoulders after sleeping, the cause may be something else, such as bed bugs, so an inspection is worth having to be sure.

If you are concerned about the bites, a pharmacist or GP can advise on the skin reaction itself.

Step two: record it and tell the right person

If you are renting, tell the landlord or letting agent in writing soon after moving in, and include dates and photos. Who arranges and pays for treatment depends on the tenancy and the circumstances, so read your tenancy agreement and check current official guidance rather than assuming either way.

If you have bought the property, the previous owners may have left pets or the house may simply have stood empty. Keep any records of the move-in date, as they can be useful if there is a later conversation about the condition of the property.

Be factual and polite. A clear, dated message tends to get a quicker, calmer response than an angry one.

• Take dated photos of bites, specks and any fleas
• Write down the date you moved in and when bites began
• Send a written message to the landlord or agent
• Keep copies of everything

Step three: avoid making it worse

Do not spread your belongings around the whole house until you know how far the fleas have spread. Keep bedding and clothes washed hot, and vacuum daily, emptying the cleaner outside into a sealed bag.

Be careful with shop-bought foggers. They are often used in a panic and can miss the hidden stages, and they carry risks if used wrongly. Follow the label strictly and keep children and pets out of treated areas.

If you have a pet, treat the animal with a vet-recommended product before it sets foot in the new home, so it does not become a host and keep the cycle going.

Step four: get the property assessed

An inspection will confirm whether fleas are the problem, how many rooms are affected and whether there is a source such as wildlife in a loft or under floors. A good plan covers the whole property, not just the bedroom where the bites started.

Essex Pest Solutions treats fleas in homes and rental properties, and can explain what preparation is needed. Treatment goes more smoothly when everyone involved, whether tenant, landlord or agent, knows what is required and when.
