Any non toxic backyard spray?

[Lrosell31]

So my backyard is getting pretty smelly especially since we got a good amount of rain last night. Is there any non toxic or maybe homemade spray I can use to spray the backyard to help with the smell. My birds have free range of my backyard.

Ummmm maybe a couple bags of sweet lime? You should be able to put it down with a drop spreader, or just toss it free hand... Not sure how big your yard is...
