We signed up for service with Official during their door-to-door visits in our neighborhood. We had tiny spiders upstairs for a couple months and even after we bombed they were back not long after. Initial service included inside spray and the spiders were gone! Depending on season changes we occasional see larger spiders, but as soon as I contact Official, they are out as soon as possible and the spiders are gone! Reps are always nice and helpful! I love when they wipe down the webs outside too! Has been totally worth it for our family and I recommend to friends and family often!
