What are Household Spiders?

Spiders are arachnids, just like ticks. However, there are many different types of household spiders. They are usually considered more of a nuisance because of their webs. Female spiders can lay up to 250 eggs at a time. Also, they can produce approximately 17 egg sacs in a lifetime (up to 3,760 eggs total). Varieties of household spiders include wolf spiders, daddy longlegs, jumping spiders, and many more.

The most common household spiders are the house spider, cellar spider, and wolf spider. The house spider is what most people see indoors. It is no bigger than 5/16” with a round abdomen. They range widely in color but are mostly grayish or yellowish-to-brown. A cellar spider is long and thin, grey in color and hangs upside down in their webs. When disturbed they will shake the webs or spin on a string. Wolf spiders are hairy hunting spiders. Females often carry their young on their back after hatching. Wolf spiders do not normally live inside, but may wander in.

Are they harmful?

While spiders tend to scare people they are generally harmless and not aggressive. Hobo spiders, black widows, and brown recluse spiders can bite and cause infection if not treated properly. On top of this, female spiders can breed quickly and as a result can create an infestation. With the thousands of eggs that can be laid in their lifetime, spider infestations can happen quickly. Spiders can also indicate the presence of other pests that may be living in your house, so be aware.

How can you treat them?

Keep leaf litter and debris away from home. If you must use outside lighting, then choose non-white bulbs. Insects are attracted to the white lights (positive phototaxis) and then spiders come for a free meal. Also check indoor window treatments. You might not have outside light but may be shining lights from inside.
