Do not let the rain water (...blank)... otherwise mosquitoes can emerge as a big problem.

Can I use the verbs like:

gather or accumulate?

I would like to know both the spoken and formal.

Thanks in advance.

    The idiomatic standard for this context is Mosquitoes breed in standing water. So although it's a relatively uncommon verb form in other contexts, I suggest Don't let the rain water stand, otherwise mosquitoes... Commented Feb 19, 2020 at 14:20

You could easily use gather. Accumulate is a little bit more formal, but would also get the point across.

You might also want to think about using the verb to pool as in Pooled rain water will easily become a breeding ground for mosquitoes.
