What affects the price

• Property size: more rooms mean more product and time.

• Pets in the home: vets may also recommend pet treatment alongside the house spray.
• Preparation: some companies charge more if the property isn''t vacuumed and cleared before they arrive.

What''s included in a professional flea treatment

A typical visit includes an insecticide spray on carpets, upholstery, skirting boards and pet bedding. Many companies also include a follow-up visit to check activity and re-treat if needed. You will usually need to vacuum daily and wash pet bedding.

Can you treat fleas yourself?

Over-the-counter sprays and foggers can help a mild problem, but they often miss eggs and larvae in cracks and soft furnishings. A professional uses stronger, longer-lasting products and treats the whole lifecycle. If fleas keep coming back, it''s worth calling a pro.

How to keep the cost down

• Treat pets at the same time — otherwise fleas will reinfest the house.
• Vacuum thoroughly before the visit and dispose of the bag immediately.
• Book a follow-up only if you still see fleas after two weeks.
• Get quotes from a few local companies to compare.
