Sierra Pest Control Reno Black Widow Spider

While spiders and cobwebs might make great Halloween decorations, we cannot imagine anyone saying they are looking for an actual live eight-legged critter to make an appearance in their home. Autumn is thought of as “spider season” to many due to people judging insect seasons on the amount they notice inside their home.

Just like humans, spiders begin the find their way indoors to escape the cold weather. This causing people to notice more spiders in their space and associate the time of year with the eight-legged creature. Spiders can sneak in through tiny cracks and crevices on the exterior of your home and quickly spin webs to set-up for winter in the attic, basement, or other less-frequented parts of your home.

In Indiana and Kentucky, there are many different kinds of spiders you make notice encroaching on your space. While most are afraid and jump at the sight of any spider, only a few of them are a threat to humans. According to the National Pest Management Association (NPMA), there are about 3,000 species of spiders throughout North America, but only two in the southern and western United States can actually cause serious harm to humans when they are accidentally disturbed. Below are spiders that you may potentially notice throughout Central and Southern Indiana, as well as Kentucky.

Black Widow Spider
As most know, this is one of two spider species in the United States that is potentially dangerous to people. This spider is black and most recognized by the red hourglass shape on its abdomen. An average female is about ½ inch with a leg span stretching 1.5 inches or so. Only the female of the species post a threat to humans, and while their bites are rarely life threatening, they can cause serious discomfort such as muscle cramping, abdominal pain, nausea, and tremors. Small children, the elderly, and people with compromised immune systems may be at higher risk for more severe reactions to these bites.

Brown Recluse Spider
A brown recluse is the other species that can be potentially dangerous to humans throughout the United States. The body of a brown recluse is about 1/3 inch with a leg span of 1 to 1.5 inches. They are recognizable by their brown color and typical violin-shaped darker patch on their body. A bite from a a brown recluse may cause a large open sore causing damage to the skin and tissue around the bite. People with these bites may also report abdominal cramping, fever, and stiff joints.

Wolf Spiders
There are over 100 species of wolf spiders found in the United States and Canada. These spiders are often large and hairy which alarms most people, but they are primarily only a nuisance pest. They may bite humans if continuously provoked, but their bites are not medically threatening. Unlike most spiders, wolf spiders don’t hunt with webs but rather they chase their prey using their fast running ability. Fun fact – The wolf spider is the spider that can be found on many of the Black Diamond service vehicles!

Common House Spiders
The common house spider is usually the spider that people most often encountered indoors. It is a nuisance pest probably more because of the webs it spins inside people’s homes rather than the spider itself. These spiders rarely bite unless they feel threatened (i.e. when created in shoes or clothing being put on by a human). The house spider is found worldwide and is common throughout the United States and Canada.

Jumping Spiders
There are about 300 species of jumping spiders found in the United States and Canada. Jumping spiders are unlikely to infest the indoors though. This species tends to flee from humans rather than attack. Unlike most spiders, they are active during the day and seem to like sunshine.

Long-bodied Cellar Spiders
These spiders are commonly referred to as “daddy-long-legs” because of their very long, thin legs. As their name implies, long-bodied cellar spiders are often found in dark and damp places like cellars and basements. While they may be a nuisance around homes and businesses as they infest common storage areas, these spiders are harmless and do not bite people.
