Yellowjacket Wasps
Late summer is the time of year when populations of
yellowjackets (commonly called "bees") and other social wasps
become large and noticeable. Yellowjackets build paper nests similar to
hornets, but either in the ground, a log or landscape timber or building
wall or attic. If a nest is located where it is out of the way and not
likely to be disturbed, it is best left alone. If, however, a nest is
located in a "high traffic" area such as along walks or near
doorways, control is justified to reduce the threat of being stung.
Bumble Bees
Bumble bees are big, fuzzy insects recognized by almost
everyone by their robust shape and black and yellow coloration. The
common species are 3/4 inch in length or more. Bumble bees usually nest
in the ground in a deserted mouse nest or bird nest. Occasionally they
nest in cavities within a wall or even in the clothes drier vent. If the
vicinity of a bumble bee nest can be avoided, then leaving them alone
and waiting for them to die in the fall would be the preferred
"management" option. However, bumble bee nests are often found
in yards, flowers beds, wood piles, or walls in high traffic places
where the threat of being stung is great.
Trapping bumble bees
is not practical and exclusion techniques may not solve the problem.
When controlling bumble bees is necessary, using insecticides to poison
bee colonies is the control method of choice.
Brown Recluse
Spider
Adult brown recluse spiders are soft-bodied, yellowish-tan to
dark brown, about 1/4 to 1/2 inch long and have long, delicate grayish
to dark brown legs covered with short, dark hairs. The leg span is about
the size of a half dollar. Distinguishing characteristics are the
presence of three pairs of eyes arranged in a semicircle on the forepart
of the head and a violin-shaped, dark marking immediately behind the
semicircle of eyes with the neck of the violin pointing towards the
bulbous abdomen.
The severity of a
person's reaction to the bite depends on the amount of venom injected
and individual sensitivity to it. Bite effects may be nothing at all,
immediate or delayed. Some may not be aware of the bite for 2 to 8
hours, whereas others feel a stinging sensation usually followed by
intense pain if there is a severe reaction. A small white blister
usually rises at the bite site surrounded by a large congested and
swollen area. Within 24 to 36 hours, a systemic reaction may occur with
the victim characterized by restlessness, fever, chills, nausea,
weakness and joint pain. The affected area enlarges, becomes inflamed
and the tissue is hard to the touch. The spider's venom contains an
enzyme that destroys cell membranes in the wound area with affected
tissue gradually sloughing away, exposing underlying tissues. Within 24
hours, the bite site can erupt into a "volcano lesion" (a hole
in the flesh due to damaged, gangrenous tissue).
The open wound may
range from the size of an adult's thumbnail to the span of a hand. The
sunken, ulcerating sore may heal slowly up to 6 to 8 weeks. Full
recovery may take several months and scarring may remain. Plastic
surgery and skin grafts are sometimes required.
The
brown recluse spider is not aggressive and normally bites only when
crushed, handled or disturbed. It is aptly named since it is a reclusive
creature seeking and preferring seclusion.
