I've had Bulwark for about 9 months now and am really starting to think they are spraying stuff that attracts bugs rather than kill them. We signed up for the scorpion service, and am being charged 60$ a month to include monthly service and any service in between if there are problems. Well it's getting to the point where we are calling every week. Everytime we call they try and tell us,with an extra 25$ we can get the scorpion treatment. WTH?! We signed up for the scorpion treatment from the get go and need these things gone! We have little ones in the house and it's gotten worse in the 9 months! So basically 600$ later and the scorpions have gotten worse, not better! And they still try and up sell us. And also crickets as well. Not sure what these guys are using, but they say they specialize in scorpion treatment but really just think they come out so people have the piece of mind. I'm trying to stick it out since they keep making promises, and will update my review if it gets better, but at this point if you have scorpions stay away from bulwark.
