Wasps can be red, black, brown even metallic blue.
Some 250 varieties can be found in the U.S. They
don't seek a fight, but become extremely hostile
when protecting the nest.
Different species of wasps will exhibit different
nesting behaviors. You have to know which species
are solitary and which ones swarm in numbers. Mud
daubers nest in tubes of dried mud. Paper wasps chew
wood into a paper like pulp to create hanging nests
on shady areas of your property. Hornets create
tear-shaped nests on the sides of buildings or
hanging from eaves or trees. Some wasps favor the
undersides of wooden decks. Yellow jackets enter
your property from cracks in your siding and gaps in
your soffits. You can often locate a wasp nesting
site by carefully watching individuals as they
forage, then converge on the hive. But be careful -
you may not be able to see the whole hive or the
extent of the wasp infestation.
