I'd be grateful if someone could give me some advice re: a couple of nests we've discovered recently. We live in a bungalow and have wasps nesting in one of the ventilation spaces right at the bottom of the wall - in the brick. (I think they're German Wasps but they could also be Common Wasps - I haven't got close enough for a proper identification). Today, we've also seen Honey Bees going into another of these ventilation spaces - presumably another nest?
I'd just like to know whether these insects would be doing any damage to the property by nesting there or would they just be taking their own nesting material in to fill up the cavity. Also, if we don't disturb them and just leave them to their own devices, are they likely to sting us?
