Unfortunately the job needs doing this week.. I thought brick over the hole with a long rope attached for pulling it off after.. large can of wasp spray for those not inside and a paramedic on standby if that fails :ffsparr:
Later in the week I've got to prune a Hawthorne hedge and bang next to it is a wasps nest in the ground... if I put a object over the hole for say 30 mins will this harm them?
