Before wasps decide to move into your home, you can employ a strategy to keep them away. First, remove food from anywhere outside the home and be sure to cover your trash can. Also, since wasps hate the smell of mint, planting mint in the garden is a good deterrent. Alternately, dab a few cotton balls with peppermint oil and put them in places where wasps are likely to build a nest.
If the natural method doesn’t work, it may be time to call an exterminator. A pest control specialist will come to your home with light modification, traps and insecticidal controls to get rid of the wasps. Large hives may require physical removal and cleanup.
