Would you rather …… be locked in a room with a thousand mosquitoes
or
be locked in a room with twenty bees?
Why??

I'd rather be locked in a room with 20 bees.

Explanation: The bees won't sting you unless you bother them. There are no limits to the number of mosquito bites a mosquito can inflict. After they have consumed enough blood, the mosquito will rest for a couple days (usually between two to three days) before laying her eggs. Once this is complete she is ready to bite again. When a honeybee stings a mammal, its barbed stinger lodges in its skin, and the honeybee cannot remove it. Instead, it leaves the double lancet behind, along with part of its digestive tract, muscles and nerves. This abdominal rupture is what kills the bee.
