Houseplants That Attract Bed Bugs and Plants That Help Repel Them

Houseplants can soothe your thoughts and brighten up a room, but a few varieties can also encourage far less welcome visitors.

With more homes filling lounges and bedrooms with leafy greenery, an unexpected knock-on effect can appear: some plants seem to give bed bugs and other pests a reason to linger. Choosing the right plants can help keep things in check, while the wrong mix can make infestations easier to sustain.

Why some plants can attract bed bugs and other pests

Bed bugs don’t eat plants. They live on blood and usually feed at night while you’re asleep. So why do houseplants make any difference? The connection is the tiny “micro-habitat” that plants create indoors.

Thick growth, dim corners and warm, slightly humid areas around pots can provide convenient places to conceal themselves. Pollen and fallen plant material can also attract other insects, which then occupy the same seams, gaps and crevices. One quiet corner can become a small hotspot of activity, and bed bugs take advantage of that cover between feeds.

Plants do not “cause” bed bugs, but certain species and growing conditions can make a flat or bedroom easier for them to occupy discreetly.

If you pick plants that commonly host sap-sucking insects, or ones that drop lots of organic matter, you effectively increase both “traffic” and hiding opportunities. In a home already dealing with bed bugs, that extra cover can delay spotting the problem and make treatment harder.

Three plants you may want to rethink if you fear bed bugs

Several popular choices show up more often in pest-friendly homes - not because the plants themselves are to blame, but because they bring along issues you may not notice straight away.

Sunflowers: beautiful, messy magnets for bugs

Sunflowers can look wonderfully upbeat in pots or large containers on balconies. Indoors, however, they can create a few practical problems. They often draw aphids, thrips and other tiny insects that feed on their stems and foliage. Once established, those insects can spread to nearby fabrics, rugs and the gaps around skirting boards.

They also drop a good amount of pollen and small fragments. If you keep them near a window close to a bed or sofa, that spot can quickly become a thriving mini-ecosystem. Bed bugs may then shelter behind the pot, beneath the saucer, or even within curtain folds beside it, benefiting from shade and reduced disturbance.

Chamomile: soothing for humans, inviting for small pests

Chamomile tea is widely associated with relaxation. Yet the plant, when kept in indoor pots, can attract whiteflies and aphids. Inside, those insects don’t have the usual natural controls such as ladybirds or lacewings, so populations can rise fast.

That extra insect activity also means more movement and fine debris. A chamomile plant placed in the bedroom - near the headboard or on a bedside table - can unintentionally provide a sheltered “backdrop” that bed bugs use. They need an undisturbed daytime refuge close to their food source, and a cluster of small pots can offer exactly that.

Dandelion: tough survivor, unhelpful indoors

Dandelions aren’t a common choice for houseplants, but they can hitch a ride in garden compost or appear as “bonus” seedlings in mixed planters. They tolerate poor conditions and can attract various sap-feeding insects and mites.

Indoors, a stray dandelion tucked into a big container or near a balcony door can bring both dense, low-level foliage and plenty of organic litter. Bed bugs tend to travel along floor edges and under rugs; a large pot with ground-hugging greenery can provide extra cover, shade and “bridges” right where shoes, bags and laundry often end up.

Sunflowers, chamomile and dandelions do not feed bed bugs, but they can reshape the indoor environment in a way that favours pests.

Plants that help repel bed bugs and other insects

Greenery isn’t automatically a problem. Some strongly scented plants can have the opposite effect, helping to make your home less attractive to insects.

Lavender: a fragrant ally for your bedroom

Lavender contains essential oils that many insects avoid. Its scent won’t eliminate an established bed bug infestation, but it can help reduce general insect activity around windows, drawers and textiles.

• Keep a pot of lavender by a bright, sunny window, rather than on a bedside table.
• Trim it regularly so dead material doesn’t build up on the compost.
• Put dried sprigs into breathable sachets near wardrobes to create a mild deterrent.

There’s also a mental health angle: lavender’s fragrance can ease anxiety, which is common once people begin to worry about pests at home.

Lemongrass and citronella: summer guardians at doors and windows

Lemongrass and citronella give off strong citrus aromas that deter mosquitoes and many other flying insects. Fewer insects around windows and balcony doors means fewer “hitchhikers” being carried inside on clothes or bags.

Grow them in medium-sized pots near entry points. Keep the leaves neat, and don’t let water sit in saucers, as stagnant water can attract fungus gnats and mosquitoes rather than discouraging them.

The hidden pros and cons of indoor plants

Beyond bed bugs, houseplants influence your indoor environment in other ways. Some behave almost like natural filters. Plants such as areca palm, snake plant and peace lily may absorb certain volatile compounds released by paint, cleaning products and furniture finishes.

Many people also find they feel more upbeat and focused when working or relaxing in a room with plants. Living greenery can soften the hard edges of furniture and screens, dampen sound slightly, and add gentle variation in light and shadow.

Plants can enrich indoor air, soften noise and support mental health, while at the same time changing humidity and shelter patterns for pests.

When plants turn risky: toxicity and humidity

A number of much-loved houseplants have toxic sap or berries. Ficus varieties, holly and several ornamental shrubs can cause stomach upset or irritation if eaten. Most adults won’t nibble leaves, but pets and young children are more likely to test things with their mouths.

Keep these plants well out of reach and make a conscious note of what you’re growing. If you buy second-hand planters or inherit pots from family, take time to identify each plant before placing anything in a nursery or play area.

Humidity is the other key issue. Plants release moisture through their leaves and require regular watering. In a well-ventilated, fairly dry home, that added moisture can improve comfort. In a basement flat, an older property with cold walls, or a poorly ventilated bathroom, extra humidity can encourage mould and fungi.

Mould doesn’t just harm walls and furnishings; it can worsen asthma, allergies and some skin problems. Bed bugs don’t eat mould, but damp, cluttered areas are often cleaned less often. That lack of thorough cleaning leaves more undisturbed spaces and fabric folds where bed bugs can establish themselves.

Plant type	Potential benefit	Potential risk
Lavender	Aroma disliked by many insects, calming effect	Can dry out quickly, leaf litter around pot
Areca palm	Helps filter indoor air, lush visual effect	Needs frequent watering, raises humidity
Sunflower (indoors)	Bright décor, seasonal interest	Attracts aphids and thrips, sheds pollen and debris
Chamomile (indoors)	Herbal use, soft fragrance	Hosts whiteflies and aphids, extra insect traffic
Dandelion in pots	Hardy, low-effort greenery	Encourages pests, messy organic matter

How to keep plants without boosting your bed bug risk

You can enjoy houseplants and still keep a bed-bug-free flat, provided you follow a few straightforward routines.

• Don’t pack large, dense groups of pots right beside beds, sofas or upholstered headboards.
• Check the compost surface and the undersides of leaves each week for aphids, mites or whiteflies.
• Use sticky traps for flying insects near problem plants instead of relying on heavy chemical treatments.
• Vacuum around pots, skirting boards and beneath furniture on a regular timetable.
• Isolate any new plant in a separate room for a fortnight before moving it near sleeping spaces.

If you’re already dealing with bed bugs, most professionals advise reducing clutter rather than adding to it. That may mean temporarily removing large potted plants from the bedroom until treatment is complete. Keeping plants in another room or out on a balcony can cut down hiding places near the bed, which is where bed bugs concentrate their activity.

When to seek expert advice

Staff at reputable garden centres can suggest plants that suit your light, humidity and day-to-day routines. They can also point out ornamentals that may be toxic to pets or young children. Getting that guidance early can prevent wasted money and future headaches.

If you suspect bed bugs, a professional pest controller is still the most dependable route. They inspect more than just the mattress, checking furniture joints, picture frames and, yes, the bases of plant pots and stands. Tell them where your plants are kept so those areas can be examined properly.

When you start thinking of plants as micro-habitats rather than purely decoration, you naturally arrange your home differently. You notice which corners stay damp, which shelves gather dust, and which fabrics never see daylight. Small changes like these can reduce pest risk, ease allergy problems and keep your plants as part of the solution rather than part of the problem.
