turn on the water
There are two taps; hot and cold. Generally when you turn them on, hot or cold water gushes out depending on which one you turn on. Try it.
ants hate hair spray or even tub cleaner.
Leave a combat ant trap overnight.
Do you mean IN the tub or coming from in the walls around it?
If you mean the latter then you can rent(?) or buy an Ozone generator. It's a small, portable gizmo similar to air fresheners, but it's main output is Ozone. Air fresheners may output a small amount of this, but Ozone generators put this out in large doses.
If you can get one, put it in the areas where you think the ants are coming from; for example, close the door, and windows to your bathrom and turn this on and let it fill the rom with Ozone. This should permeates every crack and crevice and it WILL either kill them or drive them out.
Be careful tho, because you do *not* want to breath this stuff in yourself. Once you've left it run for an appropriate amount of time you will have to *thoroughly vent the room. Open the windows, run a fan...whatever it takes.
Hope it helps.
