I'd be on the safe side and have Terminix check veeeeeeeery carefully.
Now, go to TAP plastics, get some two part acrylic, mix it up and make yourself a pendant or a cool ring, spider belly up of course so people can see the red hourglass
Terminix will come back and spray again for free if you see bugs between your scheduled spray days. It is also common to see dead bugs after they've recently sprayed too.
We have a lot of spiders too, but from what I read spray are not that effective because spider does not drag their body on surfaces like other insects? So unless your spray hit the spider, it won't prevent new one to move in.
I usually don't pay too much attention to spiders... but this one with its hourglass so prominent...it stopped me in my tracks. Probably should pay more attention.
