Can fleas live in your bed long-term?
Waking up with itchy bites and the uneasy feeling that something is living in your bed is never pleasant. If you suspect fleas, then keep reading to find out the most effective way to kill them and eliminate fleas for good.
Are they fleas?
Before treating the problem, it’s worth confirming what you’re dealing with.
Fleas are:
-
Small, dark brown or black
-
Flat-bodied and very quick
-
Able to jump long distances
-
Likely to bite ankles, legs, waist and arms
If you have pets that are scratching more than usual, that’s another strong clue. Flea dirt (tiny black specks that turn reddish-brown when wet) on bedding or mattresses is also a giveaway.
Step 1: Strip and wash everything on the bed
This is the most important step because heat kills adult fleas, larvae and eggs. Even items that look clean should be washed, fleas and their eggs are easy to miss.
-
Remove all bedding, including sheets, pillowcases, duvet covers, mattress protectors and blankets.
-
Wash everything on the hottest temperature the fabric allows (ideally 60°C or higher).
-
Tumble dry on a high heat for at least 30 minutes.
Step 2: Vacuum the mattress
Fleas and their eggs can hide in seams, tufts and crevices.
-
Vacuum both sides of the mattress, paying special attention to seams and edges.
-
Vacuum the bed frame, headboard and any cracks or joints.
-
If you have a divan base, vacuum inside drawers and underneath the bed.
When you’ve finished empty the vacuum outside immediately and seal the contents in a bag before putting it in the bin. This prevents fleas from escaping back into your home.
Step 3: Treat the mattress
You don’t need to soak your mattress in chemicals, but light treatment can help. Avoid heavy use of insecticides on sleeping surfaces. Always follow product instructions and allow the mattress to dry fully before remaking the bed.
Step 4: Treat your pets at the same time
Your bed is often only a symptom of a wider flea problem. If you have pets, you must apply flea treatment as this is how the fleas are feeding. Treating your pet regularly will make sure the fleas don’t return.
Step 5: Clean your bedroom
If the infestation feels out of hand, consider investing in a household flea spray or flea fogger (also known as a flea bomb). These products help kill fleas hiding in carpets and floorboards, not just the bed.
When using these, follow the instructions carefully i.e. remove pets from the room and ventilate well before re-entering.
Step 7: Prevent fleas from coming back
Once the fleas are gone, prevention matters. Here’s what to do:
-
For your pet
Keep pets on regular flea prevention as this will keep fleas from biting your pet and causing an infestation in your home.
-
For your home
Can fleas live in your bed long-term?
Fleas prefer animals, not humans, but they will hide in beds if conditions suit them. Mattresses offer warmth, darkness and easy access to blood meals. Without treatment, fleas can survive and reproduce surprisingly quickly.
Finding fleas in your bed is stressful, but it’s a solvable problem. The key is to treat everything at once: bedding, mattress, room and pets. With heat, thorough cleaning and the right products, fleas can be eliminated and kept away.
