We have a wasp nest in the outside wall of our house. Wasps are going down the crack between the flagstones of the side path and the wall of the house.
In my area we can pay the council to have the nest treated but obviously there are private companies too.
So my question is, is there any benefit to paying more for a private company (don't know if there is differences in chemicals used or techniques) or is it just a case of they'll all do the same thing anyway. TIA
