Why Are There So Many Spiders Around My Home?

Spiders are one of the most common pests homeowners encounter throughout Michigan, especially during the warmer months and into the fall. While most spiders are harmless, large numbers of webs and spider activity around the home can quickly become frustrating.


At Brent’s Bugs, one of the most common questions we hear is:

“Why are there suddenly so many spiders around my house?”



There are several reasons spider activity increases around homes, and understanding what attracts them is the first step toward reducing the problem.

Spiders Follow Their Food Source

The biggest reason spiders move into or around a home is simple: food.


Spiders feed on insects such as:


  • Flies
  • Mosquitoes
  • Ants
  • Moths
  • Gnats
  • Beetles


If your home has a large insect population, spiders will often follow because it provides an easy food source.


Reducing other insects around the property is one of the best ways to reduce spider activity.

Outdoor Lights Attract Insects and Spiders

Bright exterior lights attract flying insects at night, which then attract spiders looking for food.

You may notice spider webs building around:


  • Porch lights
  • Garage lights
  • Entryways
  • Windows
  • Deck lighting


This is one reason spiders are commonly found near doors and outdoor lighting fixtures

Spiders Prefer Quiet, Undisturbed Areas

Spiders look for places where they can hide and build webs without being disturbed.

Common hiding areas include:


  • Basements
  • Garages
  • Attics
  • Storage boxes
  • Closets
  • Crawl spaces
  • Corners of ceilings


Outside the home, spiders often hide in:


  • Wood piles
  • Landscaping
  • Sheds
  • Bushes
  • Under decks

Seasonal Changes Increase Spider Activity

Many homeowners notice increased spider activity during late summer and fall.


As temperatures begin to cool, spiders may move indoors searching for:


  • Shelter
  • Warmth
  • Food sources


This is especially common around windows, doors, and small cracks around the exterior of the home.

Common Spiders Found Around Michigan Homes

Michigan is home to many spider species, including:


  • House spiders
  • Wolf spiders
  • Cellar spiders
  • Orb weavers
  • Jumping spiders


Most spiders found in Michigan homes are not dangerous, but large populations can still become a nuisance.

How to Reduce Spiders Around Your Home

There are several ways homeowners can help reduce spider activity:

Reduce Other Insects

Controlling insects around the property removes the food source spiders rely on.

Remove Webs Regularly

Knocking down webs discourages spiders from settling in the area

Seal Entry Points

Small cracks and gaps around windows, doors, and foundations can allow spiders inside.

Reduce Clutter

Storage boxes, piles of items, and cluttered spaces create ideal hiding areas.

Keep Landscaping Maintained

Trim bushes and remove debris near the home to reduce outdoor hiding spots.

Professional Spider Treatments Can Help

When spider activity becomes overwhelming, professional pest control treatments can help reduce both spiders and the insects attracting them.
