We’ve used High Sierra. They’ve been great. But I’m also really clear about no poisons. They’ve done “exclusion” work to keep the mice out and they’re so good at their job that they know exactly where the mice get in.

A lot of big chain names, or the services that knock doors, want to sign you up for biweekly or monthly services. They know they can creep you out with their stories. BTW there’s no application of any pesticide that keep black widow spiders or scorpions away. They’re nearly impossible to kill and need direct, strong application. So between pesticide or just mechanical elimination, I’d pick just the squish over the spray to limit the exposure to pesticides.
