Not sure where to post.
Wtf are these? Hundreds of them trying to get in my home?

?

Blackfly aphids, probably feeling cold and trying not to die! They won't cause any harm or survive long

Ok, thank you. Just wanted to know if they are biters. Im not doing much to keep them out. Only getting the odd one get in. But my windows are covered on the outside. When they do get in they just sit on the windows. Having to keep my DD 18 mo away from them. She puts everything in her mouth! This will include these bugs and slugs! 🤢
