Yup. You need to spray insecticide for 20-30 days straight because the eggs are immune until they hatch and they have like a 20 day hatch cycle.

We have these little plastic boxes with holes and roach poison inside that we stick to walls and near doors to catch the little ones that crawl in. They're good for 2 months each.

Edit:

Also forgot that I also just mix borax and sugar to kill them. Haven't had to deal with an infestation in a very long time.
