Wasps in the backyard!
I have tried the 2L bottle method using a sugar base as well as a 2L bottle of meat. They unfortunately do not seem to be interested at all.
I have now sprayed the suspected area twice with some "Wilson one shot" spray that is targeted towards wasps but it did nothing either.
Online says to try peppermint oil as they hate the smell of it so I may try that next.
Any other suggestions?
