One of my children kindly braught bed bugs home from school a few years ago. We had the house treated with heat remuneration (they raise the surface temp of your home to like 140 degrees or so do not remember exact temp for 24 hours). Needless to say I could not leave my tanks in the house and at the time I had 12 or 13 running.
So I hit walmart and baught a bunch of hard plastic tubs of varying sizes (no clear ones figured darker the better for the fish). I set all of them up under the big oak in my backyard to keep them out of direct sunlight. Then ran a heavy duty extension cord out from my garage with a 3 port splitter and 3 large powerstrips. ( I put all the electric stuff under an upside down 55gallon in case of rain moved all heaters and filter outside then the fish. Covered all of my containers with plywood(to prevent jumping) then a tarp (to prevent contamination birds ect). Than drained all my tanks so they wouldnt boil.
Then the wife and I pitched a tent next to the containers and grilled ribeyes and drank beer for the next 24 hours. We only had one problem at some point in the night my heaters flipped a breaker. the temperature drop took out both of my wifes blood parrots but everything else made it.
It was a lot of work but almost a complete success. ( oh and pest snails stink when they cook I actually saved a lot of them but what I missed ewwwwww)
Good Luck
