My Dog Has Fleas And I Have 3 Other Animals I Will Be Treating W/ Frontline But My Apartment Will Still Have ?

fleas in it but i am kinda scared about bombing the aparment. Will the fleas continue to live even though they will not be able to live on my dog b/c of the frontline? Its september and starting to get cold so that may factor in on the fleas thriving in a colder enviroment. Is there any safer affective way to treat my apartment? I dont want to bomb since i live in a apartment and is not totally safe AND one of my dogs has skin allergies. I want stop these lil pest from biting me and i want them out of me and my animals lives!!!!
