With close to 4000 different types in the USA I have decided to touch on just a few of the most popular ones

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.


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.

1. Place non-toxic diatomaceous earth around the foundation of your home and in areas of your basement and attic where spiders are most prevalent.
2. Put spider sticky traps in problem areas of your home, such as dark moist areas where spiders can be found.
3. Have the exterior of your house treated with a good residual insecticide.
4. Spray cracks and crevices inside your home with a residual insecticide.
5. Keep basement and attics clean and vacuum up all webs.

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 legs.

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 Spiders

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.

Their Webs
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.

Their Bites
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 Spiders

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.

Wolf Spider

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
The spider 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 deadly spiders.
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 dirt.
