in our first LFS we had, located in a "mini-mall" type location,our landlord/neighbor, had his pizza place next to use "de-bugged". the fumes made it thru a double concrete firewall,only to wipe out the fish system (1000 gallons) along that wall, scratching our heads as to why the fish side went to heck,only to find out the pizza place was sprayed two days prior to the fish and system crashing
gotta have the mindset that bug killin' stuff is made to seek out/permeate(sp) cracks, crevices,etc. to do it's job.make sure you consult the place that's doing the work , and let them know what you got that might be harmed,and ask for things to do to avoid problems.i've heard some good responses/advice about this in previous boards, do some archive searches, and i think you will get some good advice/info.Good Luck!
