They are simply looking for food. As long as they are wel lbehaved, as yours appear to be right now, there is no good reason to do anything that could harm these scavangers which can be helping control insect pests in your garden.

good to know, thanks. I suppose if they had a nest in there they would be a bit more pugnacious.
Meanwhile, I hope they enjoy their smorgasboard.

Wasps especially like the rose slugs that are so troublesome to us this year. Definitely let them do their thing!

Why don't you look UP..perhaps there is a nest in the eaves of your house..If they are not agressive fine..but I would like to know where the nest is just in case...

I, too, think that they are drinking, resting, feeding, or all three. You'd know it if they were building a nest in your pots.

Be careful - yellow jackets can be very aggressive and are able to sting over and over again. They're mean buggers - nothing like wasps.
