Indiana is home to many different species of spiders both indigenous and those that have become naturalized. Indiana is home to many different species of spiders both indigenous and those that have become naturalized. These fairly common household pests and the reason for numerous calls to Indiana pest control companies. And with the cold winter weather, like people many of these creepy crawlies seek shelter inside homes.

Almost all spiders are capable of biting, given a target they can fit in their mandible, but most only cause a few squeals and perhaps a red, itchy bump. Here are two spiders common to Indiana that are a bit more dangerous.

Brown Recluse

The brown recluse spider does call portions of Indiana home and is a significant danger. This spider is capable of delivering a bite that, while not typically fatal, can cause serious damage to its victim. Its presence in a home may require professional pest control measures.

These are unassuming looking spiders: smallish, leggy and brown. They like dark, quiet spots where they won’t be disturbed. They usually roam at night, looking for food. Their webs are messy masses of silk that may be found in dark corners, under furniture or in the garage. Outside they can often be found in the recesses of a woodpile or underneath rocks. They are not usually aggressive and typically bite only when they come into direct contact with humans and feel threatened.

The bite of a brown recluse starts as a relatively painless spot. Within a few hours at most, it becomes a red, swollen and intensely painful lesion. It may take on the appearance of an indention in the skin which becomes ulcerated. This is evidence of tissue death and can lead to a painful infection and a large scar if left untreated.

Pest extermination measures should be taken to eradicate this spider from a home or business. It may not be fatal, but its bite can leave deep scars the size of a lemon on the affected area. Regular treatments can lessen the likelihood of this spider taking up residence indoors.

Sac Spider

The sac spider is named for the silken bag it weaves high on wall or other places of retreat. They remain in their sacs during the day. Like the brown recluse, they are small, nocturnal spiders that do not spin webs to trap food. Instead, they hunt it down. Most measure only a few millimeters in length so they are easily hidden in a home.

These spiders don’t normally establish colonies indoors. However, they often seek out a warm place to escape winter weather. Humans typically come into contact with sac spiders in their bedrooms at night.

Their bite is not as bad as the brown recluse, but it still packs a punch. It may feel like a wasp’s sting and may also cause an allergic reaction in sensitive systems. Their bites are known for developing secondary infections which is why they are considered a pest control problem worthy of an exterminator. This may be due to their habit of eating dead and decaying arthropods.
