A skunk
My suggestion - either get an exterminator or move house.
yes
you would have to find a hole in a tree or bee hive an cut it for bees to come out!! do not try this at home!!
Bees typically do not live inside houses, but they may build hives in or near houses if they find a suitable location, such as a hole in the wall or attic. It is important to contact a professional beekeeper or pest control expert to safely remove any beehives from a house.
Only two, as long as the light bulb has a hole, large enough for them to enter!
A dime sized hole.
A hole the size of a quarter is plenty big enough to allow entrance to a bat.
I would use a "hole saw".
Through a small hole in the base.
That would be a Whale.
A wealthy Roman was most likely a politician. They would wake up every day to have slaves do their work and they lived in large houses with a large hole in the roof and a large basin underneath it. The hole was used to let light in to the house because there were no windows and the basin caught rainwater that they used for cleaning and drinking. They would have slaves go to the market to get goods and they would meet to discuss politics in the town building.
Either you have a way that they are getting in from outside (hole in a window screen, an unsealed door, open fan in the attic, open doors, open garage, etc.) and they are coming in because they smell something good or you have a nest in your house. My girlfriend had a bee or two coming into her dorm room every day for a week only to discover an enormous hive over the light in the middle of the room. Soon, dozens of bees would flood into her room every day, buzzing and dying in her room. Eventually they taped over the hole and the bees kept to themselves. But you might want to get that checked on. Tah!
