Watch Out for That Web: Spider Prevention Tips


As fall ushers in, so do seasonal decorations. Although you may come in contact with ghosts and gremlins, spider sightings can be most common in the fall – and not just as Halloween decorations!

Rummaging through storage areas to retrieve holiday décor or to put away summer toys can put you face to face with spiders—not something you or spiders relish. To help you to stay separated from unsuspecting arachnids, here are some things you should know:

What they like:  Spiders prefer dark and undisturbed areas; they prey primarily on other insects and prefer to stay away from humans. Primary entry points for homes are through cracks or gaps in windows, doors and plumbing.

What can you do to stay pest free? Keep them outside.

Broken Window Screen

  • Make sure windows and doors, as well as weather stripping, screens and door sweeps, fit tightly and have no rips or tears.
  • Seal or caulk cracks and crevices where spiders can enter the house
  • Don’t leave gloves, shoes or boots outside where spiders can easily crawl inside.  Always make sure to thoroughly check them for sleeping spiders before putting them on or bringing them inside.

Spider Biology: Understand the biology, understand the spider.

Spiders are particularly resourceful, and if webs are damaged, spiders go to work rebuilding webs almost immediately. The purpose of the web is not only a home but to catch prey, so having the web is essential to providing sustenance for the spider.

Spiders stay where they are welcome and there is food.  To keep the spider population at bay, install yellow or sodium vapor light bulbs (bug lights) outdoors since these tend to attract fewer insects for spiders to eat.  Knock down webs when you find them; webs on shrubs and buildings can be controlled with regular hosing with a water stream.  The spiders will usually rebuild their webs elsewhere that’s a bit more inviting!
