Wasps are at their most aggressive in Autumn although with them surviving on our sugary foods and drinks, we may notice them more in the summer months. The continental, yellow and black, wasps are common in the Sussex area and tend to be more dangerous than the common wasp. It is important not to aggravate wasps as they will sting if they are looking for energy from your sugary snacks and equally, wasp nests will often need professional attention to be controlled and removed safely.
