    Did they study the paint chemicals themselves to see if that by itself was a natural bug repellant?

    Did they check if the paint chemicals are even safe for cows?

    🤔

      I haven’t read the study, but most of these would need a placebo group, so divide the herd into thirds, one with no paint, one with stripes, and one fully painted white to get a baseline for each group. Also would be good to randomize which group each cow goes in each day so to rule out one cow who is especially tasty to flies.

        Also blindfold the scientists and the cows so it’s double blind. We don’t want the cows acting in a fly-attracting way because of placebo.

        Those groups also have another characteristic that changes: the amount of the cow covered in paint.

        How do you determine if its that vs the stripes or colors?

      What if it’s just the white stripes (not the band)? Do white cows have the same number of flies? What if you paint them with black stripes?

      Maybe those are answered in the article, but I’ll never read it.

        LOL, same. Not worth the reading time. Any which way you twist it, there’s still probably way too many unknown factors.

      I’ve not seen the study referenced, but if I were doing it I’d have cows I painted with white paint, white stripes, black paint, and a control I left unpainted.

        Yes, obviously. But are the flies possibly repelled by the paint? Are the flies even able to bite through the paint?

        Edit: 50% stripes, 50% reduction in bug bites.

        Coincidence? I think not.
