The light bulb traps are to indicate the severity of an infestation, not to actually eradicate them.
You need to treat the whole house with indorex or acclaim (I have no idea why the pest control person wanted your pets out for 7 days, whatever they use should be safe once it dries, within an hour or so!)
By whole house I mean:
Between sofa cushions.
Along all carpet joins
All floorboard cracks
Under furniture
Along skirting boards
Any mattresses
Wash things on hot, steam things you cannot wash or treat.
Then treat any pets - these will amost certainly be cat fleas as those are the most common and most other types don't live on anything but the host species (dog fleas, cat fleas and human fleas do) for long but remember none of them live ON the host species for long anyway, most of their life is spent in your soft furnishings and crevices in flooring. The fact you still have an ongoing infestation means whatever you've treated the house with is ineffective or hasn't been applied effectively.
Use whatever the vet is currently selling - anything over the counter has come off SQP/Veterinary prescription only licence and that normally means it is now less effective. The only place those flea collars you buy in the pet stores is suitable for is inside your hoover bag!
If you have animals allergic to fleas use a product that kills them quickly, like Capstar, and then follow this up with a longer term treatment.
Also worm your pets, fleas are part of the tapeworm lifecycle.
If after a few weeks you are still seeing fleas, you need to look at who is bringing them into the house quickly enough that you see them before they die. Sometimes you find your cat is going out and sitting somewhere riddled with fleas and bringing them home.. sometimes its a human vector!
