Yep I did that, but unf it seemed to attract more Yellowjackets!
Used the hose and then put in fridge on extra cold. (At least cold enough to freeze a watermelon I had in there last summer?) Im figuring it will have similar effect to freezer, but you needed to leave it longer. Weeks rather than days. This extract is from Queensland gov article - small hive beetle are prevalent up north.
When temperature reaches -12?C, all stages of small hive beetle will be killed. Existing cold rooms used for wax moth control can also be used by holding equipment at 1-9?C for 8 days. Equipment should be held in a freezer for 6 hours then for 12 days at 1-9?C to overcome thermal inertia.
