Does the first precept require me to check the shower for bugs and make sure to remove all of the bugs before using it?

I recently noticed that perhaps fewer than 10 bugs seem to be in my shower. I can try to remove all of the bugs from the shower before using it so that they don’t get washed away and killed. However, some of the bugs are very small and hard to see, so I can’t be sure I can remove all of them. Also, even if I remove all of the bugs in the shower, it is possible bugs will return, so I don’t know if I need to check the shower for bugs before each time that I use it.
