how to get rid of fleas out my house?

The reason that they are back is because the bombing just killed the adult fleas. It should have had a follow up or two to kill ones that hatched from eggs.

There are products that you can use on your house that are all natural. Some are better than others, but I would suggest the one below, leave it out in a few areas of your home where you have seen fleas. It will work well.

David B is right, you should choose termite control expert that really knows what to do, if that's the case that eggs should be killled too, your pest control guy should do that also. God thing Orlando has the best Pest Control in Oviedo. Really helped us for many years now.

If you don't have pets , are you sure these are fleas

As with any infestation I dose is not enough

You should all ways do this twice to be certain all eggs is dead too
