You’re welcome. Most effective time is right at daylight. They are cool and ever so slightly slower than normal.
I use this method to destroy beehives that are too ‘hot’ to manage safely. All it takes to reuse the frames for another colony is a good fresh water rinse and let dry.
Fill a garden sprayer with heavy soap mixture (1cup dawn to 1 gallon water). Stick the end in the entrance hole and let it loose. The foaming will work better than pouring. Dawn will also not hurt the compost terribly bad. Kills bees instantaneously.
