Answer:
Sounds more like mud-daubers, a kind of wasp . Pour gasoline down the hole after it cools down at night , when they are lethargic. Throw dirt into the hole and cover with a rock, preferably a large flat rock. Keep kids and pets away, and this spot won't be fit for planting for a year or two. Check the rest of your property , including nooks and crannies outside your house. If you find mud clumps with a little entry hole, spray with direct stream wasp and hornet spray , again at night, and saturate it.
