Can Bedbugs Live Outside or in the Garden in Hounslow?

People ask this for two reasons. Either they have bites after an evening outside and wonder whether bedbugs have come from the garden, or they have bedbugs indoors and wonder whether putting the furniture in the garden will kill them. The answer to both starts with how bedbugs live.

Why Bedbugs Do Not Live Outdoors

A bedbug needs a person who comes back to the same place night after night, and a dry, sheltered crack close to that place to hide in. A bedroom provides both. A lawn, a flower bed or a hedge provides neither: nobody sleeps there, and wet, open ground is no use to an insect that spends its life pressed into seams and joints.

They are also carried, not wanderers. They do not travel across gardens from next door or drop from trees. When they reach a new home, it is almost always inside a bag, a piece of furniture or someone’s belongings.

Garden Furniture and Cushions

Outdoor chairs and tables are not a home for them. Cushions are a small exception when they spend the winter indoors: seat pads that come in from the patio and get stacked beside a bed, or piled onto a sofa bed in the spare room, are just soft fabric with seams. If there are bedbugs in that room, the cushions can carry them.

Putting an infested mattress or sofa out in the garden in the hope that weather will deal with it rarely works. Bedbugs can go a long time without feeding, and a cold spell does not reliably reach into the middle of a mattress. Moving it out also drags it through the house. Leave it where it is until we have looked.

Sheds, Garden Rooms and Summerhouses

A shed full of tools is no more attractive than a lawn. A garden room is different if someone sleeps in it. An office with a sofa bed used for a lodger, a teenager who moves out to the summerhouse, or a relative staying in a converted outbuilding turns it into a bedroom as far as bedbugs are concerned.

The same applies to things stored in a shed. A second-hand bed frame or a bag of bedding from a house clearance, left in the shed until someone needs it, can hold bedbugs until it comes back indoors. Check anything like that carefully before it goes into a bedroom.

What Else Bites Outside

If the bites happened in the garden, other culprits are far more likely:

• Mosquitoes and midges, especially near still water, in the evening.
• Fleas, carried by pets, foxes or other animals that pass through the garden.
• Harvest mites in long grass in late summer, often around ankles and waistbands.
• Ants and other small insects when sitting on the ground.
• Bird mites, occasionally, when a nest near a window or in the eaves is abandoned.

Bites look alike across these, so the pattern of the bite tells you little. What you find is what counts. Our London guide on whether it is bedbugs or something else goes through the differences.

When to Look Indoors Instead

If the bites appear overnight rather than after time outside, look at the bed: the seams and piping of the mattress, the corners and joints of the frame, and the back of the headboard. Dark spotting, pale shed skins or a live insect there mean it is worth ringing us. If you are unsure, an inspection from £120 settles it; the Hounslow inspections page explains the visit, and the Hounslow bedbug page covers treatment.
