Types of Spiders in Concord, Massachusetts

There are nine main species of spiders living in Concord, MA, and each of them has a unique appearance, behavior, and impact on homeowners. Here is a brief overview of the main spider species living in Concord and a look at how to identify them:

Black Widow Spider

One of the most feared and recognizable spiders in the world, the black widow is a black and shiny spider with a reddish brown hourglass-shaped marking on its abdomen. It is an aggressive hunter and has strong and deadly venom; if a bite is untreated, it can lead to dangerous health complications. Black widows like to hide in tight, dark spaces and are most commonly found in basements, storage areas, and backyard sheds.

Brown Recluse Spider

The brown recluse spider is light to dark brown in color and has a distinct violin-shaped marking on its back. It is not aggressive and generally avoids humans, but it can deliver a highly toxic bite that can cause severe necrotic lesions. Brown recluses hide in dark places such as wood piles, storage boxes, and basements.

Wolf Spider

The wolf spider is grayish in color and can grow up to a half-inch in length. It is a solitary hunter and does not make webs. It runs quickly and is usually seen in open areas like grassy meadows or in places around the home like basements, attics, and garages.

House Spider

House spiders are small spiders (half-inch in size or less) with yellow, gray, and black markings. These spiders make a cobweb to catch their prey, and their webs can often be seen in corners, window sills, and closets. They are harmless to humans and generally avoid confrontation.

Hobo Spider

The hobo spider is a large brown spider with a patch of gray on its abdomen. It is often mistaken for the brown recluse, but it is a less dangerous species and does not usually bite humans. Hobo spiders can be found in places like woodpiles and garages, and they typically build irregular webs.

Garden Spider

Garden spiders are large (up to an inch long) and usually black and yellow in color. They catch and eat other insects and usually build large and intricate webs in gardens and around the outside of houses. Although they usually remain outside, they can sometimes be seen in houses when the weather turns cold.

Assessing the Risk of a Spider Infestation

Before taking any action to remove a spider infestation, it is important to first assess the risks presented by the spiders present. As discussed earlier, some spiders, such as black widows and brown recluses, are inherently more dangerous than others like wolf spiders and house spiders. Take the time to examine your home and assess the likelihood of an infestation by any of these dangerous species, and remove any spiders that you come across.

It is also important to consider the environment around your home. Where do you live? Are there any gardens or wood piles nearby? Are there any entry points to your home that may make it easier for spiders to get in? Knowing the possible entry points and environmental factors can help you better assess the risk of a spider infestation.

Methods for Prevention and Removing Spiders

Once you have assessed the possible risks posed by a spider infestation, it is time to take action. The first step in any spider-removal process is to prevent their entry into your home as much as possible. Take some time to inspect your home and seal any potential entry points cracks in windows and doors, spaces around wires and pipes, and openings around the foundation, for example. This will help reduce the risk of any spiders entering your home and reduce the chances of an infestation.

Once you have sealed any potential entry points, you can begin to take steps to remove existing spiders in your home. This can be done by using a vacuum cleaner, chemical sprays, or a combination of both. If you choose to use chemical sprays, be sure to follow the directions and take all necessary safety precautions.
