perimeter or wherever you have them. I'd recommend going outside with a black light as well and spraying then so you can see where they hang out outside your home. You can spray and kill with some channel lock pliers at the same time. I think consistent nighttime hunting helps as much as anything. I'd make sure your kids and pets are away from the areas you spray for a bit so that is why I think nighttime spraying works the best.

I've used Suspend SC and Bifen IT, but any of the 5 star rated pesticides will probably do the job.
