What You Need To Know About Yellow Sac Spiders

While most any kind of bug is not a welcome sight in your home, the eight-legged kind can be especially worrisome. Not only does the sight of a spider make your skin crawl, but some of them are venomous and therefore have potentially harmful bites.

A perhaps lesser-known spider that you should be aware of is known as a yellow sac spider. This spider belongs to the Cheiracanthium genus and consists of two different species: C. mildei and C. inclusum. Both of these critters can be quite a pest should they find their way into your home. Fortunately, the two species have a great deal in common and can be handled identically in most situations. Consider a few key facts that may help you identify yellow sac spiders and take appropriate next steps for spider removal.

Are They Dangerous?

Although the venomous bite of a yellow sac spider may resemble a brown recluse, it is not nearly as severe. Even so, the area near the bite may become red and swell somewhat. Additionally, the bite can cause a bit of skin tissue to die, known as a necrotic effect. These bites may be painful for a short time after the bite, but these symptoms should go away on their own without any severe side effects. You may wish to treat a bite with an ice pack, but be sure to see a medical professional if you experience any serious symptoms.

What Do They Look Like?

Yellow sac spiders, as their name suggests, are usually a pale yellow colour; however, they can at times be slightly green. The bottom of their legs, on the other hand, are generally brown. These critters grow to about a quarter inch in length and are often marked with a dark line on their backs. 

Where Do They Live?

Unlike many of the spiders you may be familiar with, yellow sac spiders do not build webs. Instead, they create sacs made of silk. Because they hunt at night, you can expect to find these arachnids in their sacs during the day. This is also where they lay their eggs—up to 48 of them at a time.

Yellow sac spiders generally enter houses as the weather grows colder in the early fall. If they have moved into your space, the ceilings and corners in your home may be a favourite hiding spot of theirs. When they are outside, a common area to find one of these bugs is in your garden. 

What Do You If You Have an Infestation?

If you spot yellow sac spiders or even just their sacs somewhere in your home, there are a couple of things you can do. For one, you may wish to eliminate their entry points by adding new caulking around windows, replacing weather stripping around doors and filling in any other visible gaps. Additionally, you can use your vacuum or a cloth to eliminate the sacs you have located.
