Spiders are beneficial predators that help to control populations of garden insects and other nuisance pests. Spiders are arachnids, and unlike insects that have three body regions, only have two body regions: the cephalothorax (head) and abdomen (body). Additionally, all spiders have eight long legs. Although spiders are beneficial to the environment when living outdoors, some species of these intimidating arachnids pose a certain danger to people and pets.
Three of the most common species of spiders living throughout our area of Louisiana are the following:
Black widow spiders These spiders have round bodies and eight eyes that are arranged in two rows. Black widow spiders are shiny and black in color with a reddish-orange, hourglass-shaped marking on their abdomens; some black widow spiders may also have light red or white spots on their abdomens and backs.
Brown recluse spiders As their name describes, brown recluse spiders are light brown in color with a darker brown, violin-shaped marking on their backs. A brown recluse spider has six eyes arranged in three groups of two, in a semicircle-like pattern.
Wolf spiders Wolf spiders are a large species of spiders; their stout bodies are covered in hair and are usually black or dark brown with lighter markings. Wolf spiders use their eight long legs to quickly chase their prey. These spiders have eight eyes that arranged uniquely in three rows.
Are spiders dangerous?
Whether a spider is dangerous or not depends on its species. Both the black widow spider and the brown recluse spider are considered to be dangerous species of spiders. Both of these spiders possess venom that is strong enough to cause health problems in people. Most species of spiders that we run into daily are nuisance pests and harmless to people. Typical household-invading spiders, such as the wolf spider, do not have venom that is strong enough to harm a person.
Why do I have a spider problem?
Most spiders prefer living outside on properties that offer them safe, secluded, and sheltered areas to hide out in. Spiders are shy and reclusive by nature and prefer to stay out of the view of people and predators. While they mainly live outdoors, they will move inside of homes and outbuildings if the weather outside becomes too cold, hot, or wet. Spiders will also move indoors when tracking prey, and properties that have problems with insects will often have issues with spiders as well.
Where will I find spiders?
Spiders build their webs – or burrows, in the case of wolf spiders – in a variety of locations. Doorways, gardens, roof eaves, shrubs, tall grasses, and under decks are all places where you will find spiders. They can also be seen crawling on and hiding behind wooden shingles found on the exterior of homes as well as barns, garages, and other outbuildings. Spiders that have moved indoors usually choose dark, secluded areas to hide in such as basements, closets, crawlspaces, and under furniture.
