Wasps set up shop in the corner of your kitchen window? This is not uncommon. It is this time of year that these wasps are setting up shop for the summer. If you happen to stumble upon one of their nest, it is important not to over react. Take a look at the size and activity of the nest, and then come up with a plan. If there are just a few bees and the nest is accessible enough , you may be able to just knock the nest down with the pressure of a garden hose. Stand far away because the water will not kill the wasps, but the nest will be gone. Also be aware that the wasps that were out looking for food will be returning and not happy to find their home gone. So be aware of agitated wasps.
If the nests are more involved or larger, you may need to use a wasp spray that can attack the nest from afar. If the nest is bigger than you can handle, always call a professional.
