Fleas are a difficult pest to tackle – we talked to our Which? Trusted Traders endorsed pest controllers to find out how to get rid of them.
Fleas are an unwelcome visitor to any household. They are quite common, particularly if you have a pet, which will almost inevitably come into contact with other flea-carrying animals. Fleas have several life stages – they start as eggs, hatch into larvae and mature into adult fleas, which will bite humans, animals and birds to feed on their blood. Flea larvae tend to live on carpets or bedding, where they feed on organic debris and adult fleas' excrement.
Fleas can remain dormant for as long as 12 months. They can be awoken by vibrations, such as footsteps, and are then attracted to carbon dioxide and body heat. ‘What often happens is that someone moves into a property where there was a cat or dog in the past,’ Which? Trusted trader The Pest Controller’s Philip Voller told us. ’Dormant eggs will hatch, and people find themselves being bitten shortly afterwards.’
If you need to get rid of fleas from your home, Which? Trusted Traders has endorsed pest controllers in your local area.
The bite usually looks like a heat spot: ‘a red welt’ rather than a raised lump. Some people develop a rash.
Fleas are becoming more resistant to some of the more popular over-the-counter remedies. So if you have a cat or dog and think they could have fleas, the first step is to visit a vet, who will be able to advise on a suitable course of treatment.
Usually, treating your pet will eliminate the problem. But if you don't have pets, or the flea problem persists despite treatment, try these steps.
1. Vacuum thoroughly
Regular, careful vacuuming is important to tackle flea eggs, larvae and adults. Empty the contents of the vacuum outside into a plastic bag, and put this in an outside bin straight away.
2. Hot wash
Wash clothes and bedding at a hot temperature, at least 60°C. Check the label before you shrink your favourite items, though.
3. The big freeze
Cushions, delicate clothes, children’s stuffed toys and anything else that can’t be hot-washed can be frozen instead. Wrap everything in a bin bag and place it in the freezer overnight.
4. Flea spray
You can buy this at the vet or from a DIY store. You should carry out the spraying at the same time as washing and freezing your belongings, otherwise you risk reintroducing fleas to your clothes and bedding. But be aware that fleas are becoming increasingly resistant to common chemical treatments.
5. Flea powder
Use this underneath the carpet to kill off the flea larvae, according to the manufacturer’s instructions. Flea larvae spend 80% of their time in the base of the carpet, around the twisted pile fibres.
6. Flea lamp
If these measures, in combination, don’t work, you could try a flea lamp. Costing around £15, they consist of a small lamp and circle of glue inside a tub. The fleas are attracted to the heat, mistaking it for the human body. They become stuck to the glue as they jump around.
‘If you have pets, ensure you remove them from the room, otherwise this won’t work,’ Greg Ferguson advised. ‘You have to leave the lamp on overnight, with the pet out of the room, and then remove the lamp (and the fleas) the next morning.’
If DIY treatments aren’t getting rid of your flea problem, then it’s time to call in a professional. Always ask how the pest-control company proposes to treat the problem, and how its quotes work. Is it quoting per room or for the whole house, for example? It’s also worth finding out whether the company offers any kind of guarantee. You want to be sure the fleas are gone after paying for the treatment.
‘We’d recommend treating any pets first,’ Greg Ferguson said. ‘Once that’s taken care of, your pest controller will essentially fumigate the house. We spray the skirting boards, the carpets, under the sofas – everywhere the fleas are likely to be. You have to stay out of the house for about five hours afterwards to allow it to dry. It could be longer if there are a lot of carpets or soft furnishings.’
A treatment will cost somewhere between £150 and £350, depending on the size of your property and the nature of the furnishings. Moving furniture is labour intensive, and a good pest controller needs to be thorough. For example, they will remove the cushions from a sofa in order to spray the nooks and crannies.
