With close to 4000 different types in the USA I have decided to touch on just a few of the most popular
|BROWN RECLUSE SPIDER
BROWN RECLUSE SPIDER
Bites occur year-round in heated homes where the temperature
remains constant. Bites normally do not occur in areas of the united states where cold weather is common, although one large
upstate New York hospital reported over one thousand brown recluse bites in a one year period of time. These bites were not
confirmed to be that of the brown recluse. I do know of some confirmed bites in New York State but the victims or their family
had just returned from southern states. Brown recluse spiders are sometimes carried into the northern states by crawling
into travelers or vacationers luggage. The recluse is non-aggressive towards humans but it will defend itself when rolled
on, touched, or handled in any way. Most bites are reported to occur in the bedroom while the victim is sleeping. When a brown
recluse bites, it injects cytotoxins that cause tissue death or necrosis of the bitten area . Many brown recluse spider bites
go unnoticed initially or result in mild stinging. Some people may feel a burning sensation within 30 minutes after the brown
recluse bite. Then, within 8 hours after the brown recluse bite, a necrotic spot may develop which can enlarge to the
size of a silver dollar. If these symptoms do not appear within 48 to 96 hours, necrosis is not likely. If these symptoms
do appear, the area can become ulcerated and sunken. Lesions caused by the brown recluse bite may take months to heal.

The brown recluse is
also known as the fiddler spider or the violin spider.
WHAT TO DO IF BITTEN BY A BROWN RECLUSE
First aid for someone who has been
bitten by a brown recluse spider includes use of an ice pack to prevent or to reduce the swelling in the area where the brown
recluse bite occurred. Cooling the brown recluse spider bite area helps to reduce tissue damage. Also, cleaning
the brown recluse bite area with hydrogen peroxide or alcohol will help to prevent infection. You should seek medical
attention right away. If the brown recluse spider can be found, it should be collected and taken with the patient to the doctor
to confirm the identity of the spider bite involved.

THE YELLOW SAC SPIDER
What do Yellow
Sac spiders look like? They are long and thin. The yellow sac spider is light green to yellow white with a dark
stripe on the front of its body. It has 8 eyes in three rows. It is 3/4 inches long. They like to roam the ceilings and walls
looking for something to eat. Mainly neotropical, this family has 36 species north of Mexico. Those yellow sac spiders have
two claws at the tip of the leg. The jaws are brown and the legs are very smooth with the front legs longer than the rear
THE YELLOW SAC BITE
Yellow sac spiders are responsible for most bites in the united
states. The yellow sac spider is the most common spider in north america.Yellow Sac spiders are
the most active at night.A Bite by a yellow sac spider generally produce instant, intense stinging pain, not unlike that of
the bite of a wasp or hornet. This may be followed by localized redness, swelling and itching in the spider bite
area; these spider bites may or may not evolve into a necrotic lesion, but when that occurs healing of the yellow
sac bite is usually complete within eight weeks. Systemic effects are usually not severe, but when they occur may include chills, fever, headache, dizziness,
nausea, anorexia, and sometimes shock. Treament for the local lesion spider bites should follow the same protocols as
outlined for the hobo spider bite and brown recluse spiders spider bites
|hobo spider picture
What do hobo spiders look like.
Hobo Spider's are brown or gray and about 1" to 1 3/4" when full grown. Their legs show no distinct rings and
short hairs, and they have chevron shaped markings on their abdomens. The most distinctive characteristic of the hobo
spider is on their under-side. The two back legs will have small black spots near their body.
The hobo spider builds funnel-shaped
webs in dark, moist areas such as basements, window wells, wood piles, and around the perimeter of homes. The hobo spider
is a fast-running brown spider with a herringbone or multiple chevron pattern on the top of the abdomen.
Most hobo spider bites occur when the Hobo
spider gets into bedding or clothing and is trapped next to the skin. Commonly, the hobo spider is found in crawl spaces
beneath homes and around out buildings. The initial bite is not painful, but a hard area appears in 30 minutes. Numbing sensations
and dizziness may occur. An expanded reddened area that can be 2 inches in diameter or greater may surround the bite. The
bite area blisters in 15 to 35 hours. The blister breaks in 24 hours, and the area around the bite may slough, causing a slow-healing
wound. Though this sounds ominous, the bite is not considered to be fatal. But those who are sensitive might experience more
serious medical complications and fatalities are known to have occurred. So if you suspect you have been bitten by a Hobo
spider, it is advised that you seek medical attention.
Hobo spider bites
most commonly occur when a person picks up firewood with a hobo spider on it or when a spider finds its way into clothing
or bedding. Reactions to bites of the hobo spider are similar to those caused by brown recluse spiders. The major difference
between the two is that sometimes the bite of the hobo spider is accompanied by a severe headache that does not respond to
aspirin. The hobo spider has not been documented in California, but it has been documented as expanding its range into other
states that border Washington and Oregon.
Wolf Spider Bite
Symptoms of a Wolf spider bite are usually
minor, restricted to local pain or itchiness. Less commonly, symptoms of the wolf spider can include swelling, prolonged
pain, dizziness, rapid pulse and nausea. Vinegar will ease the pain of a bite.
What Does a Wolf Spider Look Like.
These spiders are recognizable by the position of their eyes which are mounted on the
front of a more or less vertical head region. Four of the eyes are large and arranged in a square while the remaining 4 are
smaller and set in a row beneath the larger. The back of the wolf spider is often patterned in radiating bands of browns
and the top of the abdomen with similar coloured markings. Wolf spider's spend their entire lives on the ground. Females live
in a permanent burrow in the soil while male wolf spiders live a more nomadic life and do not have a permanent burrow.
How They Hunt
that you see wandering across the garden path or between plants on a summer day or night is quite likely a common Wolf Spider.
The wolf spider is fast moving, hunting in the open ground and low vegetation during day and night.This
heavy-legged spider, like its mammalian namesake, is the classic arachnid hunter. Found east of the Rocky Mountains, the wolf
spider sets up in woodland debris or rocks, like a duck hunter in a blind, and patiently waits for prey to approach. If none
comes, the wolf spider will stalk and then run down any insect it finds, usually at night. Like all spiders, wolf
spiders inject venom, paralyzing their victims with a toxin that both predigests and preserves the insects for later consumption.
Catch a wolf in the beam of your flashlight, and its eyes will glow like a deer's. their eyesight
is very important to them. Since a wolf spider hunts their prey instead of building a web to catch it, they need
good vision. Having eight eyes helps!
Where They Are Found. Wolf spiders are widespread across all the continents except Antarctica.
The wolf spiders are often numerous, especially around leaf litter in parks and gardens. A wolf spider is more active
at night or overcast days. They live in burrows with other wolf spiders. The wolf spider is a fascinating
spider. It appears to be common throughout the world yet very few people recognize it as well as some other large and
The Mother Will Give Her Life For The Babies, at Least at First. When the female
wolf spider has her spiderlings in the cocoon she guards it with her life. But when the spiderlings are hatched,
if one of them fall off her back they have to hurry up and get back on or stay there to die because the mom will not
come back to get itís spiderling.
Problems With House Spiders
Your site is very informative, however I was wondering specifically how spiders enter the home, and if there are anything
that I can do to prevent the spiders from biting me. I also would like to know what spider inhabit Rochester, NY. We are
in Charlotte, and will be moving to Rochester and want to know if this area is more prone to spiders in the home because we
will be located so close to the lake, or because our foundation surrounding our home is comprised of more sand than normal
