The triangulate cobweb spider is believed to be native to Eurasia and is assumed to have been spread through the trading of goods. Pestcom Pest Management will share more about the triangulate cobweb spider, where they hide in homes, and how you can protect your home from their intrusion.

Identification of Triangulate Cobweb Spiders

The triangulate cobweb spider size can range from 0.13 to 0.25 of an inch in length. The cephalothorax is usually a brown-orange color. However, different species vary on coloring. The abdomen is the same color with a triangle shape pattern which is how they got their name. The abdomen can also be a cream color with a purple-brown zigzag pattern underneath the triangle pattern on the upper section of the abdomen. The legs are usually seen in yellowish hues.

Triangulate Cobweb Spider Diet & Habitat

The triangulate cobweb spider is most frequently sighted in homes during March and April. They spin cobweb style webs that consist of irregular tangles of sticky silk. The triangulate cobweb spider has poor eye sight and relies on their web vibration. Sensing the slightest vibration, their web helps them catch their prey. Their webs can also help them detect danger. The force of the vibration will allow the triangulate cobweb spider to know when it’s prey or a predator. The triangulate cobweb spider will feed on ants, spiders, pill bugs, and even ticks. One benefit of having a triangulate cobweb spider invasion is that they will feed on other spiders that are known to be harmful to humans such as black widows and other venomous spiders.

Triangulate Cobweb Spider Bites

The bite of the triangulate cobweb spider isn’t known to be harmful and there have been no reported illnesses occurring from a triangulate cobweb spider bite. They aren’t an aggressive spider and will retreat when they feel threatened.

Triangulate Spider Prevention

To help prevent triangulate cobweb spiders from invading your home, you will first want to keep them from wandering in. Start by making sure your home is secured from spiders. Begin by inspecting windows. Make sure all of the windows are fully closed and that the window screens are secured and are in good condition. Windows often serve as an access point for many pests. The same thing can be said for doors. Next, inspect your entry doors. Go inside and see if you see any daylight along the edges of the door. If you see light, it is an entry point for spiders and pests. You may need to repair the weather stripping around the doors. Next inspect your home’s exterior walls and foundation. Look for cracks or gaps. If found, use caulking glue to fill in the holes. Lastly, install screen covers over dryer and attic vents and over chimneys to help keep spiders and other pests out of your home.
