If anyone tells you they have a wasp nest and are going to treat it themselves then get them to watch this clip. Wasps behaviour can change in literally seconds and a true professional pest controller will be able to notice a change in behaviour early or even predict their behaviour and allow for this when treating a nest. When I surveyed the nest in the clip I was aware of there busy activity and they appeared very volatile so I prepared for the treatment knowing they would get very aggressive very quickly and wanted to record it. As soon as I treated the wasp nest by injecting some powder I shut the window immediately and started to record. If that was someone trying to treat the nest it could of gone horribly wrong and that's when people get seriously injured and even end up in hospital. Why would you risk it and end up with the possibility of getting seriously injured. Get a professional in who knows what he is doing.
It is about this time of the year that we start to see a change in wasp behaviour. Up until now the Queen wasp has been building her nest, not physically but producing lots of female workers to go out and get the materials to build the nest (wood pulp). Whilst they are doing this the Queen is busy laying thousands of eggs which turn into wasp larvae, some of the workers are responsible for looking after the larvae and some go out hunting gathering soft bodied invertebrates, such as aphids to feed the larvae. Wasps themselves do not eat the food but chew up the prey and feed it to the developing larvae. The wasps live on a sweet excretion of spit produced by the larvae that is a sugar. So as we get to the end of the summer time; late August, early September the queen stops producing female workers and starts producing males and then Queens. Once the Queen stops laying and there are no more larvae the workers loose their food source and have to turn to fruits such as apples and pears, normally found fallen under fruit trees. This can be a problem as fermenting fruits contain alcohol so they can literally get drunk. They will go to great lengths to get the sugars they need which is when they become very irritating and persistent around food. They are hungry and want food and they will retaliate with a sting if they are prevented from reaching it. Wasps are not bad creatures, if you think about it, they are survivalists. They are only ever worried about expanding their nest and defending it but also looking after their young. If that’s not survival then what is?
