diatomaceaous earth (http://www.earthworkshealth.com/) apply the dust to the floor and it will desiccate them and kill them. Alternatively, Cedar oil fog. It is all natural and will kill them. http://www.pestigator.com/.
Also, what may help is also applying a growth regulator that will prevent the larva from reaching adult stage, and brake the cycle. You can also apply natural pyrethum powder (dried powdered chrysanthemum flowers) along with the DE. It is what I use on the carpet when I get fleas in the carpet. I've also had to use the growth regulator to finally get rid of them. I would spray the floors with the growth regulator first and after it dried, dust the floor with the DE and pyrethum powder. Fogging the house with the Cedar oil would also kill the bugs (I don't know about eggs though).
