F.A.Q.

A mouse nest is a loosely woven ball of shredded material, roughly the size of a softball. Mice build them from whatever soft material is available: paper, insulation, fabric, cardboard, dried grass, or string.

All hornets are wasps, but not all wasps are hornets. Hornets are generally larger, more aggressive when their nest is threatened, and build bigger, enclosed nests. Most other common wasps, like paper wasps and yellow jackets, are smaller and nest differently.
