Last year we had a wasps nest removed form our loft.
The past 2 days we’ve been getting a wasp coming into our en-suite (window is always open) and we have just found it starting to build on our fan heater (tiny 2cm collection of stuff at the minute). We obviously don’t want the nest to build so short of closing the window is there anything else we need to do? Is this the queen coming in and if so would catching and “disposing” of her help?
