Ouch, sounds fun
An alternative to the stapro insecticide is Ficam-W, very effective stuff.
Going back to your original post Tony, you can't kill eggs unless you find them and squish them, could be a long job
It's a real problem treating creepy crawlies, because insecticides only kill adults and larvae, they won't deal with eggs or pupae. There's a product called Nylar which is a growth inhibitor. After killing off what you can with insecticide, the growth inhibitor will stop any further new insects which have hatched out from going on to the next part of the life cycle.
Obviously with fleas you're still going to have a load more biting adults, but they won't reproduce so you'll eventually snuff the population out. You can mix it with your normal insecticide, so no messing around with separate sprays.
I use a garden type sprayer with conical jet for insecticide, doesn't clog up so much and cheap enough to be dedicated for those few times it's needed.
