How to Identify Common Spiders


Tarantulas are very large spiders and can reach up to 6 inches in size. They occur naturally in the Southwestern United States, but keep watch for them if you live in the Boston or Dedham area as they are sometimes found in houses. Tarantulas are non-venomous, and they prefer the outdoors, so if you see one, it’s probably just passing through.

Black and Yellow Garden Spiders

The black and yellow garden spider can reach up to 3 inches in size and be recognized for its distinctive color pattern of yellow and black stripes. Black and yellow garden spiders prefer outdoors and build webs to catch prey. While they cannot bite humans, they can be seen as a nuisance, and they can find their way into your home via an open window or door if given the opportunity.

Wolf Spiders

These spiders are most active in the summer and spring when they make their dens outdoors and hunt prey. They are medium-sized spiders and can be recognized for their pattern of colors, which includes gray, brown, and black. As with most spiders, wolf spiders are harmless to humans and prefer outdoor living.

Brown Recluse Spiders

These spiders are native to the South-central and midwestern United States, but they have started to move to Massachusetts and can be found in southern New England. These spiders are venomous and can cause inflammation and redness in the bitten area. Brown recluses are light brown in color and have a dark violin-shaped marking on their back. They prefer to live in dark, quiet places, such as attics and basements of homes.

Prevention and Prevention Tips

Inspect your property regularly to identify potential spider hot-spots

Inspect the exterior of your home for places where spiders might hide. Take extra caution around drains, window wells, doorways, garages, and barns. Make sure to inspect behind large appliances, furniture, and curtains.

Reduce clutter around the house

Reducing the amount of clutter around the house is an effective way to reduce the potential hiding places for spiders. Regularly organize and clean your home. Pay special attention to places where dust may accumulate, such as closets and cabinets.

Keep entry points sealed

Check all of the doors and windows in your home to make sure there are no tiny openings where spiders can enter. Make sure to seal any cracks and crevices in the walls and around the foundation. You should also install window and door screens, which can help to prevent spiders from entering your home.

Pyrethroid-based insecticides

If you are dealing with a spider infestation, you can use a pyrethroid-based insecticide to eliminate them. These insecticides can be found in many retail stores and should always be used in accordance with the instructions on the product label.

Hire a professional

If you have a severe spider problem, it is best to hire an experienced exterminator who can provide efficient and safe pest control. Professional exterminators have access to more powerful insecticides that can effectively kill off the spider infestation.
