I don't know the names of anyone with Bulwark, but I'm happy with their services so far.
Initial phone call: friendly, professional, and informative.
Price: Competitive.
Initial spraying: guy was really friendly and wore shoe coverings in my house and he said he liked working for Bulwark (because I like to chat with people as I follow them around my house).
Regular service: so far so good...no scorpions in my house this summer yet! Last summer I counted 22 scorpions INSIDE my house during the hot months...(not all at once). The summer before that I counted 18 scorpions INSIDE...and stung by one in my bed!
Friendly and quickly answered the phone when I called.
I have no complaints....as long as I don't see any scorpions in my house.
