Signs you have a wasp infestation
Live wasps - wasps will fly in and out of the nest during the day in search of food and nest building materials. The insects will keep expanding their dwelling if left undisturbed to do so. Note that the nest can grow to the size of a football by late summer, accommodating thousands of aggressive stingers.
Wasp nest - the most effective way to find the nest is if you observe carefully the insects’ daily flight. After a while, you will be able to notice that they keep returning to the same spot over and over again. This is when it would be a good idea to book expert wasp control. However, mind that you may also be harassed by wasps, which have actually settled on your neighbour’s property.
