Two cats, second one arrived last spring with fleas. Both cats long-ish hair. Treated them both, then stopped checking for a bit and they had a resurgence late summer. At that point started treating them both monthly with Broadline, cleaned and treated the house (and lawn), combed regularly etc.
A few months on and I've just combed one of them and discovered two live mature fleas and a few bits of excrement. Over the winter this has happened a couple of times, mainly with this one cat that brought the fleas in the first place. But it's definitely not an infestation like it was last spring, or late summer.
How does it work with fleas? has it been quieter over the winter because they thrive on heat? or is it the case that there's still eggs maturing in the house that then jump onto the cats, but because the Broadline is working, they are just passengers there for a short time, rather than being able to set up house on them and cause an infestation?
Would love some advice from someone who has lived long-term with fleas, or whose cats seem to attract them? (Our first cat remains generally flea free most of the time)
