Help! Lady beetles are ruining my garden!

Yes, you have the 28-spotted ladybird and its larvae on your hands there – it’s a huge pest. If you plan to eat any crops that they are destroying, it’s best to deal with them organically. Squash the larvae and beetles, and wipe off any eggs on the underside of leaves, so you break the life cycle.
