This diatomaceous earth comes well packaged.

This diatomaceous earth came well packaged. I like to keep extra on hand to use in my barn cat area (I sprinkle it in the litter area to help keep the fly population down in warmer weather.

How van I rate this when I just received it. I'm sure it's fine, but I don't get why Walmart asked to rate everything as soon as it delivered. I'll Tate the delivery, the driver, but can't rate the product until I use it. You guys would most likely get a lot more responses if you send a questionnaire after a week or two.
