Diatomaceous Earth, it takes a little longer to eradicate the problem but it invariably does. Spiders and millipedes as well. It's also very inexpensive. You'll want food grade diatomaceous earth for use in a living area. They have a specific insecticidal diatomaceous earth mixed with other chemicals for the periphery of your home or for cracks in the foundation, window wells, etc... There is also a diatomaceous earth for pools, avoid it, it's processed in a way where it can be a respiratory hazard. Online resources for practical application are ubiquitous.
