Before the visit

  1. Treat your pets with a vet-recommended flea product, ideally a day or two before the visit
  2. Wash all pet bedding and any throws, blankets or cushion covers on a hot wash
  3. Clear the floors of toys, shoes, clothes and anything stored under beds, so the technician can treat the whole floor
  4. Vacuum every room, including stairs, under furniture, along skirting, inside sofa seams and in the car if your pet travels in it. Empty the vacuum outside into a sealed bag
  5. Cover fish tanks and switch off air pumps, and move other small pets such as birds and rodents out of the treated rooms
  6. Arrange for people and pets to be out for a few hours during and after treatment

After the visit

  • Stay out of treated rooms until the floors are completely dry, usually a few hours
  • Keep vacuuming daily for at least two weeks; this makes pupae hatch and contact the treatment
  • Do not wash or shampoo carpets for at least two weeks
  • Keep treating pets as your vet advises
  • Expect to see some fleas for up to two to three weeks; this is normal as the life cycle completes

When to call us back

If you are still seeing lots of fleas after three to four weeks, call us. A second treatment is sometimes needed in heavy infestations.
