Bumble bees live in small nests and do not swarm.
The bumble bee will only attack if it feels that its life is in danger.
During the spring, the males seek out females who are hovering around unfinished wood signaling that they want to build a nest.
Male carpenter bees tend to be territorial and will buzz around you if you approach closely, sometimes hovering a short distance in front of your face or buzzing around your head. Since males have no stinger, these actions are just for show and intimidation.
The females have a stinger, but are very docile. Females will nest in a an all types of wood, but prefer weathered and unpainted wood.
Carpenter Bees are a wood wood-boring insect; they are not considered a true structural pest. They do not spread throughout the entire structure, but prefer unpainted or finished wood.
Carpenter Bees get their name from their habit of boring into wood to make galleries (nests) for the rearing of young. They do not live in a hive as honey bees do, but are
Hornets nests resemble a large, inverted tear-drop shaped ball which typically is attached to a tree, bush or side of a building. Hornet nests may contain thousands of wasps which are extremely aggressive when disturbed.
Hornets are most commonly found in hollow trees. However, hornets nests also can be found in barns, attics, hollow walls, and abandoned bee hives.
Hornet nests built-in unprotected places are covered with a brown envelope (paper) composed of chewed plant fibers. The brown color will help distinguish it from the more common gray nests of aerial nesting yellow jackets.
If a colony is disturbed, it can become very aggressive and sting. Yellow Jackets are considered beneficial insects, as they eat other insects. The Yellow Jacket colony will remain active for only one summer, after which the queens will fly away to start more colonies. The remaining ones die at the end of the summer and the nest is not reused.
All members of the bee family defend their nests, but the Yellow Jackets and hornets are the most aggressive. They may look like bumble bees, but bumble bees have thicker "waists" and fuzzy bodies.
Any treatments against yellow jackets should be done at night, because that is when they are all in the nest. Plus, they do not see well at night
Wasps are the most famous stingers of the insect world. Wasps live in communities called colonies. A well established colony of common paper wasps can have two hundred or more individuals living on a nest the size of a man´s outstretched hand.
A wasp is quite capable of stinging repeatedly. Because of its muscle structure, it can easily withdraw its stinger and sting again.
