Bed Bugs in HMOs: What Every Landlord Should Know

If you’re managing a HMO and a tenant reports bed bugs, you’re not alone – and it’s not a reflection on you or your property. Bed bugs are on the rise across the UK, and shared living spaces like HMOs are a prime target. With multiple tenants, high turnover, and shared furniture or communal areas, these pests can spread quickly if not dealt with swiftly and properly. At Charles David Casson, we help HMO landlords handle issues like this with minimum stress and maximum efficiency.

Here’s how to stay on top of a potential infestation.

What Are Bed Bugs, and Why Are They a Bigger Risk in HMOs?

Bed bugs are tiny, blood-sucking insects that usually come out at night. They’re not dangerous in terms of spreading disease, but they cause itching, sleepless nights, and a lot of frustration. The real problem in HMOs? They don’t stay put. If left untreated, they can travel from room to room and even between properties via tenants’ belongings. They’re usually brought in via luggage, second-hand furniture, or clothing – making HMOs especially vulnerable because of frequent tenant changes and shared spaces.

Who’s Responsible: You or the Tenants?
This can get complicated. In general:

• If the problem surfaces early in a tenancy and was likely already present, the landlord usually foots the bill.
• If it appears later and there’s evidence it was brought in by the tenant, you might ask them to contribute to treatment costs.

In shared homes though, pinpointing responsibility is rarely black and white. The best course is fast, professional treatment and open communication. Delays only make things worse.

What to Look Out For: Early Signs of Bed Bugs

The sooner you or your tenants spot them, the better. Common signs include:

• Small, red bite marks – often in a line
• Tiny blood spots on bedding or mattresses
• Black dots (droppings) around mattress seams or skirting boards
• A sweet, musty smell in the room
• Shed skins or even live bugs in furniture joints or bed frames
  Tenants should be encouraged to report anything suspicious straight away.

Landlord Checklist: What to Do When You Get a Report

Quick action is everything. Here’s how to stay in control:

• Respond fast – reassure tenants and arrange an inspection immediately
• Get the experts in – use a licensed pest control company with experience in treating HMOs
• Keep records – document reports, inspections, treatments and communications
• Avoid DIY fixes – these usually don’t work and can drive the bugs deeper into the building
• Stay proactive – even if the tenant caused it, stepping in early protects your wider property and avoids disputes

If you work with a letting or property management company in Chelmsford like Charles David Casson, they will usually manage this whole process on your behalf.

Prevention Tips for HMO Landlords

You can’t always stop bed bugs, but you can make it harder for them to get a foothold:

• Provide sealed, wipeable mattresses or mattress protectors
• Schedule regular inspections – especially during tenant changeovers
• Add pest control and reporting obligations into your tenancy agreements
• Avoid furnishing with second-hand items unless professionally cleaned
• Educate tenants at move-in: share a simple info sheet on signs to look for
  A clear policy and good communication help prevent small issues turning into property-wide infestations.

FAQs
Are bed bugs a sign of poor hygiene?
No. They’re not attracted to dirt—they’re drawn to warmth and carbon dioxide.

Can they move between rooms in an HMO?
Yes. They can travel through walls, electrical sockets, and shared hallways. That’s why speed is key.

Can tenants treat them themselves?
It’s not recommended. DIY products rarely work in multi-let homes and often make things worse.

How long does professional treatment take?
Typically two to three visits, depending on the severity. Your pest control provider will guide you.
