Washing up, massive Queen Wasp enters through back doors. Loud and increasingly angry.
I barricade DD and DH in the living room, and set about QW with fly swat and Raid.
Due to urgency and the bastard QW patrolling up and down kitchen I can only grab almost empty can of Raid.
Sprayed the fucker, I actually saw her sting erect. She flew around furiously, I hid outside the kitchen door. Now, nothing...I only lost sight of her for ten seconds at the most.
No dead wasp, no buzzing, backdoor was ajar but I have no proof she slipped out there.
DD has to go to bed (room next to kitchen, but we shut the door so QW won't be able to get in there).
What next? How can I be sure we're rid of the stripy arsehole?
