Mice are capable of producing six to eight babies in each litter, sometimes as many as ten. The biggest problem with mice is that they have multiple litters each year. One male and female mouse can produce up to 40 babies in one year. Multiply that by the fact that each litter will start producing babies as well within the year and you can see how quickly a couple of mice can get out of control. In just that first year those original mice can product up to 139.

The Museum of Science in Boston collects data on firefly sightings across the US. This is their sighting map for June of 2014. In general, most of the Eastern half of the United States gets fireflies. Fireflies generally live in suburban or rural areas; cities are so bright at night they can't see each other's lights to find a mate. The larva do best near water; they live in wet rotting wood and eat slugs and snails that live in moist areas. Adults hide in long grass or bushes during the day. So usually, the best places for fireflies are where a forest or field meets a water feature - swamp, stream, pond, etc. Written Sep 13, 2014.
