Hi ken, i usually do remove the flies mine catches because it sits in a window and gets no breeze or anything to blow the remains loose. If you do it very carefully you can often times remove the bug without triggering the trap but you have to be careful and it is important to note where the trigger hairs inside the trap are so you can avoid them if possible. if you do try it and you trigger a trap dont sweat it! As long as the plant gets enough sunlight it should reopen shortly after. It isnt a good idea to set off traps so often for no reason however, as the traps could possibly die from over exertion.
