Finding unexpected marks on your bedding or waking with itchy bites can leave you wondering whether bed bugs have made themselves at home.
Although unsettling, bed bugs aren’t a sign that your home is dirty. They can arrive on luggage, clothing or second-hand furniture and hide in even the most carefully kept bedrooms.
If you’re wondering how to get rid of bed bugs in a mattress, the first step is to confirm what you’re dealing with. Effective treatment usually needs to cover more than the mattress itself, with professional pest control helping you tackle the infestation properly.
Do bed bugs live in mattresses?
Yes, bed bugs can hide around mattress seams, piping and labels. But their hiding places extend beyond the mattress.
They can also shelter in bed frames, headboards, divan bases, bedside furniture and small cracks around the room. That’s why washing your sheets or buying a new mattress alone may leave the problem unresolved.
Bed bugs feed on blood and tend to hide between feeds. Spotting their hiding places is an important part of identifying and treating an infestation.
How to check for bed bugs on a mattress
Use a torch to inspect your bed carefully, paying particular attention to seams, folds and sheltered edges.
Look for:
-
Live insects: adult bed bugs are approximately 5mm long and can appear brown or reddish-brown.
-
Dark spots: small brown or black marks may be bed bug droppings.
-
Rusty or reddish stains: these can appear where a bed bug has been crushed.
-
Tiny eggs and shed skins: eggs are around 1mm long, while growing bed bugs leave skins behind.
Check the mattress edges and underside, then inspect accessible joints in the bed frame, the headboard and nearby furniture. Avoid carrying potentially infested items into other rooms.
If you find an insect, take a clear photograph or keep it in a sealed container for a pest professional to identify.
Are mattress stains always a sign of bed bugs?
No. Sweat, spills and other everyday causes can leave marks on a mattress.
An isolated stain doesn’t confirm an infestation. Look for several types of evidence and arrange an inspection if you’re unsure.
Can you identify bed bugs from bites?
Bites alone aren’t a reliable way to identify bed bugs. Other insects and skin conditions can cause similar marks, and some people don’t visibly react to bed bug bites.
Physical evidence around the bed is more useful than the appearance of a bite.
How to get rid of bed bugs in a mattress
A mattress is only one potential hiding place. The most effective approach combines identification, treatment and follow-up checks across the affected area.
1. Contact a professional pest controller
The British Pest Control Association recommends contacting a professional promptly if you suspect bed bugs.
A trained technician can confirm the pest, assess where it has spread and recommend suitable treatment. Ask what preparation is needed and whether follow-up visits will be required.
2. Contain affected bedding before moving it
Place affected bedding and clothing in sealed bags before taking them to the washing machine or another treatment area.
Keep untreated items separate from cleaned items. Avoid moving loose bedding or furniture around the home, which could spread the infestation.
3. Heat-treat suitable bedding and clothing
NHS guidance recommends washing affected bedding and clothing at 60°C and tumble drying on a hot setting for at least 30 minutes.
Check that the fabric’s care label allows this treatment. For delicate or unsuitable items, ask your pest controller about an alternative. Washing alone may not eliminate all bed bugs and eggs.
After treatment, store clean items in fresh, sealed bags until your pest controller advises otherwise.
4. Vacuum as part of the treatment plan
Careful vacuuming can remove some bugs and eggs, but it won’t reliably eliminate an infestation by itself.
Follow your pest controller’s instructions for accessible mattress seams, bed-frame joints and surrounding areas. Seal used vacuum bags before placing them in an outside waste bin. For bagless machines, follow advice on safely emptying and cleaning the container.
5. Keep checking after treatment
Bed bug control may require more than one visit. Continue monitoring the areas your pest controller identifies and follow their instructions about cleaning, moving furniture and returning items to use.
Avoid improvised room heating or applying products to a mattress unless they are specifically approved for that use. Always follow the label and professional advice.
Can a mattress encasement help with bed bugs?
A purpose-designed bed bug encasement surrounds the whole mattress and closes with a zip. Unlike a fitted protector, it covers the underside as well as the sleeping surface.
An intact, correctly fitted mattress encasement can trap bugs already inside and reduce access to mattress hiding places. However, it won’t eliminate bugs elsewhere in the bed or room.
Our Anti Bed Bug Mattress Encasements fully surround the mattress with a zipped barrier and also provide waterproof protection.
Check the size and depth before ordering. During an infestation, follow your pest controller’s advice about fitting, cleaning and how long to keep the encasement sealed; don’t unzip it for routine airing without checking first.
Should you throw away a mattress with bed bugs?
Not necessarily. Ask your pest controller whether the mattress can be treated and retained before arranging disposal.
Replacing it while bed bugs remain elsewhere may expose the new mattress to the same infestation.
If disposal is necessary, arrange a suitable collection, contain the mattress as advised and clearly identify it as infested. Don’t donate, sell or leave it where someone might take it home.
How to reduce the risk of bringing bed bugs home
Check second-hand furniture before bringing it indoors, and inspect luggage and clothing after staying somewhere with a known infestation.
Keeping the area around your bed uncluttered makes inspection easier. Regular checks when changing your bedding can also help you notice a problem earlier.
Getting your bedroom back to comfortable
Early identification and a thorough treatment plan are the foundations of dealing with bed bugs. Focus on the whole affected area, follow professional advice and keep monitoring after treatment.
Once the infestation has been resolved, explore our mattress protectors and Anti Bed Bug Mattress Encasements to find suitable protection for your bed.
