My last cat had an injection every six months from the vet. This was not an insecticide, but rendered any flea which bit the cat infertile. In a very short time this broke the life cycle of the fleas already in the carpets/furniture and if any new flea was brought in it couldn't have babies. Worked brilliantly and I was much happier not having to fill the house with noxious chemicals.
Baby Reindeer - anyone watched it?
