Should it be 'will' or 'would'?

It has come to our attention that some residents are feeding pigeons in the estate. We advise residents to refrain from feeding the pigeons because leftover food would/will attract insects and rats into the estate.

Also, a dirty and unhygienic environment would/will pose a health problem for residents.

In paragraphs 1 and 2, should it be 'will' or 'would'?

Many thanks.
