Bug Type Promotion

So I am working on the Type Promotion and I am running into readability. I was wanting to have a dirty background so the ants/bugs would look in their natural place. However they get lost in all the details. I used a photo off the internets to see how it would look. I am planning on taking a photo of tile in the Georgia State bathrooms.

I thought about a one color background and I dont think it gets the message across. I am still working on copy for this type as well.
