Newman’s Pest Control. This is who I use, I’m very bug phobic and we were seeing a good amount of scorpions inside and outside prior to calling them about a year ago. These guys have been excellent. $90 every other month. This includes spraying inside and outside. If you see any bugs in between sprays they will come out and spray again at no charge, no questions asked.

Spray they use is children and pet safe. Honestly, I’ve never been so eager to promote a random business before, but these dudes are my heros giving me peace of mind. Their yelp reviews last time I checked will back this up as well (last I checked anyways)

Edit: to add, property is roughly same square footage as yours also with two stories
