No one wants to look up and see a spider crawling across their ceiling. To make your home less inhabitable to spiders, try out the following tips:

  1. Keep your lawn and yard trimmed. Overgrown bushes, shrubs, piles of wood, and more can attract spiders to your property and eventually indoors.
  2. Clean your home on a regular basis. Doing so can prevent insects that spiders like to prey on and eliminate hiding spots for pests.
  3. Seal any cracks and crevices. Inspect the inside and outside of your property for tiny spots that may be inviting spiders in, and seal properly.
  4. Install or repair screens on doors and windows. Holes or crevices in screens will easily invite spiders (and other pests) inside.
  5. Inspect boxes and used furniture prior to bringing them inside. Adult spiders or egg sacs could be nestled in old unopened boxes.

Are There Dangerous Spiders in the Fall?

The black widow and brown recluse spiders are dangerous any time of year, but are often seeing in or around your home in the late summer/early fall. Because these spiders can administer a dangerous bite when they are threatened, it’s important to learn how to identify them:

  • Brown recluse spiders: These spiders have a darker brown violin-shaped mark on their brown bodies. They build loose, dome-shaped webs for shelter. A brown recluse bite is known to be very painful.
  • Black widow: These spiders have a characteristic red hourglass shape on its body. They build sticky, tangled cobwebs in garages, sheds, and near the ground. They can bite when they feel threatened.

Seeing a few house spiders here and there is perfectly normal, especially this time of year. So how do you know when it’s time for a spider exterminator? If you are noticing excess webs, spiders, or dangerous spiders in your home, the experts at Johnson are here to help.

Tennessee Poison Center Offers Tips for Preventing and Treating Black Widow and Brown Recluse Spider Bites

(Newswise) — Most spiders are non-venomous and most spider bites are harmless. They may cause some local redness and pain, but can usually be managed at home by washing, applying ice and keeping the area clean.

But poisonous spiders thrive in many temperate areas of the United States, and knowing how to identify them and treat venomous spider bites is essential, said Suparna Kumar, M.D., a certified specialist in poison information at the Tennessee Poison Control Center at Vanderbilt University Medical Center.

Black Widow Spider | Pictures of Spiders“The two venomous spiders common to this area are the black widow and the brown recluse, and we have calls every year from people bitten by both of them,” Kumar said.
In 2014, the Tennessee Poison Center received almost 300 calls regarding spider bites. More than half of these were about brown recluse spiders, and 40 calls were about black widow spiders.

“Most patients bitten by these two spiders experience only minor local effects,” Kumar said. “A very small percentage of patients, particularly the very young or the elderly, may be at risk for a severe reaction to a venomous spider bite.”

Brown Recluse

Brown recluse spiders are native to Southern and Midwestern states. They are medium sized, may be light yellowish brown to dark brown in color, and are distinguished by the characteristic violin shaped mark on the back.

They seek out dark, warm, dry environments such as attics, closets, porches, barns, basements, woodpiles and old tires.

“The bite of a brown recluse may cause mild stinging or pain, and could worsen becoming painful and itchy in the next two-to-eight hours,” Kumar said. “The bite site may be itchy and red, and is often followed by the development of an extremely painful area which is usually blue or purplish in color, surrounded by grayish ring, which is in turn surrounded by a red outer ring—a typical ‘bulls eye’ pattern.”

Kumar said the recommended home treatment for a brown recluse bite is to wash the area with soap and water, apply ice, and get a tetanus booster if necessary. “The bites usually heal very well if they are kept dry and clean and left alone,” she said.

But some people develop systemic reactions to a brown recluse bite. Twenty-four to 72 hours after a bite, the patient may develop a fever, rash and muscle pain, and the toxin from the bite may be causing hemolysis, or destruction of blood cells.

“If systemic symptoms are noted, the patient will need to have his or her urine tested for the presence of hemoglobin or blood. If the urine test is positive for blood and/or the patient has signs of rash and fever, the patient should be admitted and observed for hemolysis,” Kumar said. “This is especially important in children under 12 years of age, as toxin induced hemolysis can occur very rapidly.”

The Black Widow

The Black widow spider is glossy black in color, and identifiable by a reddish or orange colored hourglass marking on the abdomen. They are usually found in dark areas such as crawl spaces, inside boxes, water meter compartments and piles of firewood.

“People who are bitten by a black widow may not even realize it at first,” Kumar said. “The bite feels like a pinprick, and often there is minimal local reaction—maybe a little bit of pain or redness at the site, which usually goes away quickly.”

If those effects are all that occur, the bite can be managed by washing the area with soap and water, applying ice, and, if needed, getting a tetanus booster.

However, some black widow bites have much more severe systemic effects. These effects may start two to four hours after the bite, and can include headache, nausea, vomiting, changes in heart rate and blood pressure, painful muscle cramping, muscle twitching in the affected extremity, and even board-like rigidity.
“If any of these symptoms are noted, the patient will need to be monitored at a hospital, and treated with muscle relaxers, narcotics or benzodiazepines,” Kumar said.

Fortunately, most spider bite patients recovers completely, but knowing how to avoid and treat such bites is critical, especially in those who encounter attics, crawlspaces and other areas where spiders live.

Black Widow Spider | Pictures of Spiders Black Widow Spider | Pictures of Spiders

The Black Widow Spider is one of the three poisonous spiders we have in the United States. The Brown Recluse is one of the other ones which we have in the state of Tennessee. The Black Widow generally is a loaner, so if you find one it is unlikely you will be finding others. They will not attack you unless they are provoked or intruded on. If they do bite you then you will want to seek medical attention. The Black Widow is very distinct with its dark black color and hour glass shaped red markings on their backsides. If you can confidently get rid of a Black Widow, without risking getting bit then feel free to do so. Otherwise consult a pest professional.House Spider | Pictures of Spider
