Most spring cleaning checklists are a list of hard surfaces. Wipe the baseboard, descale the coffee maker, do the windows, clear the gutters.
None of that is where the allergens are.
If anyone in your house sneezes their way through March and April, the things worth your weekend are the soft ones: carpet, upholstery, mattresses, bedding, curtains. That is where house dust mites live, and the numbers on how common they are are striking - 84% of US homes have detectable dust mite allergen, and roughly 8 in 10 people are exposed.
This is a spring cleaning plan organized around that, rather than around appearances.
Key Takeaways
- 84% of US homes have detectable dust mite allergen, and about 4 in 5 have it in at least one bed.
- Dust mites need humidity above 50% to thrive. Controlling humidity is more effective than any cleaning product.
- The asthma link is substantial: relative risk of asthma is almost 5 times greater at high dust mite exposure (above 10 µg/g) than at lower levels.
- The reservoirs are bedding, mattresses, upholstered furniture, carpets and curtains - not the hard surfaces on most checklists.
- Allergen-impermeable zippered covers on mattresses and pillows are the highest-value purchase.
- Vacuuming slowly matters more than vacuuming often. A fast pass skims; dwell time lifts.
- Spring is the right time because it is when pollen arrives on top of a winter's accumulation.
Why soft surfaces, specifically
House dust mites are microscopic, they feed on shed human skin, and they live in soft furnishings. They grow optimally in warm conditions at humidity above 50%, in cloth-covered objects - bedding, mattresses, upholstered furniture, soft toys, carpets and curtains.
The symptoms come from their waste and fragments, which become airborne when the material they live in is disturbed - when you sit down heavily on a sofa, turn over in bed, or walk across a carpet. That is why symptoms are often worst indoors and at night, and it is why disturbing a reservoir without removing its contents makes things temporarily worse.
Dust mites are an established asthma trigger, and the dose relationship is real: research shows the relative risk of asthma was almost five times greater in people exposed to high levels of dust mite allergen (above 10 µg/g) than in those exposed to lower levels.
Add pet dander, which collects in the same places, and spring pollen tracked in on clothes and shoes, and the soft surfaces in a house are doing most of the work of making people feel unwell.
One note before the checklist
The standard allergy guidance - from the AAFA and EPA among others - includes advice to avoid wall-to-wall carpet where possible, and to prefer low-pile carpet or washable rugs.
We clean carpets for a living, so it would be easy to leave that out. It is better to say it plainly: if someone in your household has severe, medically diagnosed dust mite allergy or asthma, reducing carpet is a legitimate intervention, and a doctor may well recommend it.
For almost everyone reading this, though, that is not the live question. You have carpet, you are not replacing it this spring, and what you want is for it to hold fewer allergens. That is a reasonable goal and it is achievable - the aim is to empty the reservoir and to control the humidity it needs, rather than to pretend the guidance does not exist.
The bedroom first - it is where you spend eight hours
Roughly four out of five US homes have dust mite allergen in at least one bed, and you breathe that air for a third of your life. Start here, not in the living room.
- Allergen-impermeable zippered covers on the mattress, pillows and comforter. This is the recommendation that does the most work for the least effort - it puts a physical barrier between you and the largest reservoir in the house. The EPA and AAFA both recommend them.
- Wash all bedding weekly in hot water, at the hottest temperature the fabric safely allows. Heat is what kills mites; a cool wash removes some allergen but leaves the population.
- Wash or replace pillows. Many are machine washable; check the label.
- Vacuum the mattress surface and sides with an upholstery tool, slowly.
- Strip the bed back and air it rather than making it immediately - a made bed traps the overnight moisture that mites need.
- Wash soft toys that live on the bed, or seal them in a bag and freeze them for several days where washing is not possible.
- Reduce clutter on and under the bed. Fewer dust-collecting surfaces, and easier floor access.
Carpets and rugs
- Vacuum slowly. Slower than feels reasonable. A vacuum needs dwell time to lift material out of the pile - fast passes skim the surface. This single change does more than buying a better machine.
- Two directions, north-south then east-west, because carpet fiber has a lean.
- Several passes in traffic lanes - doorways, in front of the sofa, the kitchen-to-table route. These hold several times the soil of open floor.
- Crevice tool along every baseboard, where dust and allergen concentrate and no vacuum head reaches.
- Move the furniture. Once a year, properly. Under the sofa and the bed is where it has been accumulating.
- Flip and vacuum the back of area rugs, which drives embedded grit out of the pile. Then vacuum the floor underneath.
- Wash washable rugs - see how to clean an area rug, and wool rugs for the fiber-specific version.
- A HEPA-filtered vacuum keeps fine particles in the machine rather than returning them to the room. Empty it outside.
Vacuuming removes surface and near-surface material. It does not empty the deep reservoir, which is the case for periodic hot water extraction below.
Upholstery and curtains
- Vacuum every upholstered piece with an upholstery tool - faces, sides, backs, and the crevice tool into every seam, where dander and dust concentrate.
- Remove and wash cushion covers where they are machine washable. Check the label.
- Check the cleaning code before anything wet - W, S, WS or X. On S fabric, water leaves rings. See upholstery cleaning codes.
- Wash curtains if they are washable, or vacuum them from top to bottom. Curtains are a reservoir and almost nobody touches them.
- Wash or replace pet bedding in hot water. If a dog sleeps on the sofa, that cushion is the most concentrated dander source in the house.
- Blinds instead of curtains, in a bedroom, if allergies are severe - they hold far less.
Humidity - the lever most people never pull
This is the item with the biggest payoff on the page, and it involves no cleaning at all.
Dust mites need relative humidity above 50% to thrive. Below that, populations decline on their own. So a hygrometer and a dehumidifier do more for a dust mite problem than any amount of scrubbing, and they keep doing it after you have finished.
- Measure it. A cheap hygrometer tells you whether you have a problem.
- Aim below 50% relative humidity, as consistently as you can manage.
- Run exhaust fans in the bathroom and kitchen, and for 20 to 30 minutes after a shower.
- Do not dry laundry on radiators indoors, which dumps a lot of water into the air.
- Ventilate on dry days; keep windows shut on humid ones. On high-pollen days, keep them shut regardless and ventilate in the evening.
Lower humidity also suppresses mold, which is a separate allergen with the same driver - mold colonizes organic materials where humidity exceeds 60%.
Pollen control, since it is spring
- Shoes off at the door. Pollen, and everything else, arrives by shoe.
- Doormats inside and out, at every external door.
- Change clothes after extended time outdoors on high-pollen days, and keep them out of the bedroom.
- Shower and wash hair before bed in peak season, so you are not transferring a day's pollen to your pillow.
- Wipe the dog down after walks. Fur is an efficient pollen carrier.
- Keep bedroom windows shut during peak pollen hours.

Frequently Asked Questions
What should be on a spring cleaning checklist for allergies?
Prioritize soft surfaces: wash all bedding hot, fit allergen-impermeable covers on mattresses and pillows, vacuum mattresses and all upholstery including seams, vacuum carpets slowly in two directions, wash or vacuum curtains, wash pet bedding, and get indoor humidity below 50%.
How common are dust mites?
84% of US homes have detectable dust mite allergen, about 4 in 5 have it in at least one bed, and roughly 8 in 10 people are exposed.
Does carpet make allergies worse?
Carpet is one of several reservoirs, alongside bedding, mattresses, upholstered furniture and curtains. Allergy guidance does suggest minimizing wall-to-wall carpet or choosing low-pile and washable rugs where allergies are severe. For an existing carpet, emptying the reservoir and controlling humidity are the practical levers.
What humidity do dust mites need?
Above 50% relative humidity. Keeping indoor humidity below that suppresses populations without any cleaning.
Does vacuuming get rid of dust mites?
It removes surface and near-surface allergen, which helps. It does not empty the deeper reservoir in carpet, upholstery and mattresses - which is the case for periodic deep extraction and for allergen-impermeable covers.
Will hot water extraction remove allergens?
It removes a great deal of the material held in the depth of carpet and upholstery, which vacuuming cannot reach. Combined with humidity control and barrier covers, it is the most effective part of a soft-surface plan.
How often should this be done?
The vacuuming and washing routine is ongoing. The full soft-surface deep clean suits spring and fall. Professional extraction depends on traffic, pets and allergies - see how often professional carpet cleaning.
The part a vacuum cannot do
A vacuum removes what is near the surface. The reservoir sits deeper in the pile and in the backing, and getting it out needs water, heat and enough suction to take it all back out again.
