I always enjoyed feeding the ducks at a local pond but I am worried maybe this isnt good for them. I also read recently that they eat slugs. If I collect slugs in my garden should I take them to the ducks instead? I never use slug pellets so they shouldnt harm the ducks.

We found a nest of spiders in a garbage can in our garage. We live in SE Wisconsin. The spiders looked exactly like black widows but had no hourglass and yellow and black on their abdomens instead of red.

I understand that spiders are very beneficial and we did not kill them rather shook them out of the can. However, I'd like to know what they are.
