You are growing this an indoor plant in a window but you don't make it clear what the problem is -is there any damage and what makes you think the fly is the culprit-?I have never heard of a strawberry fly to be honest.
My feeling is it may be the conditions and a pest is a secondary issue
Perhaps a bit more info?
Why are you growing this indoors and not outside?
