No one's been using anything.

Greetings everyone, I am new here. I registered because I am hoping someone can help me identify a phenomenon involving drosophila flies in my kitchen. Today, I looked at the window glass and saw this: Who can identify this white spray around the dead fruit flies? I've seen this before a few times, but I couldn't find any information on it (though maybe I just used the wrong search terms). Is it some kind of fungus? Best regards, andron
