I actually have a question regarding this topic as well. I am moving into a new home within the month, and we are going to bomb it before we move in. The people we are buying it from have many animals and do not treat for fleas at all and, it's bad bad. I will be setting up my new 150g within a couple days of the bomb. Does anyone see any problems with this situation?
You will want to make sure your animals are treated for tapeworms as well, especially with heavy flea infestations. Tapeworms as well as other diseases are transmitted by fleas. Lyme disease is another good thing to have your Vet treat the animals for especially where Lyme ticks (live on deer and field mice) are found.
Dont bomb... That may only kill the live fleas it comes in contact with.
Treat your animals with that stuff that goes on their neck. Vacuum the carpets well and throw out the stuff in the vacuum. You have to get rid of the eggs. The fleas will get on your animals and die. You will see them disappear in a week or so. The eggs you missed from vacuuming will hatch in a few weeks and you have to vacuum some more. Keep applying the neck treatments too. In a few months you will win this war!
