Are the Wasps bothering you? Get a jam jar. Put some jam into it. Half fill it with water – with a drop of beer if you have it. Shake it about. Put some grease-proof paper on top as a lid and secure it with an elastic band. Poke a hole in the lid with a pencil. Rub some jam about the hole and put it on the kitchen window cill (or anywhere else). Job done!!
