Yes as long as the small holes are not to close to the bottom of the
container. If your worried about them blowing around just put some 2 sided
tape on the bottonm or something heavy inside with the cotton balls.

Good luck and be patient

Is it okay to leave the container out in the rain, since it is covered?

Been using this mixture for 3 years and it works better than any store
bought ant poison I have ever used.
