A coworker referred me to Batzner when I mentioned bees/hornets flying in/out of a front window frame. They were able to come out same-day. Technician Jim Thurler was responsive with updates and very informative, explaining what the "bees" were (ground hornets) and recommendations on how to prevent future activity for other pests.
Noticed a few days later the first treatment wasn't 100% effective and they came back out right away to re-treat, free of charge.
