2. Estimate the length of the black widow’s body. Female black widows are often about a 1/2 inch long (or the size of your little finger’s nail). The abdomen’s diameter can be as small as a 1/4 inch or as big as 3/8 inch. The overall length of the female’s body will be between 1 1/2 and 1 1/3 inches.

3. Look at the underside of the black widow spider. Usually, there is a red, yellow or orange hourglass formation on a spherical abdomen. Sometimes, the hourglass will be split or separated into triangles.

4. Spot other red markings or lines around the Black Widow Spider spinnerets. Spinnerets are organs that help a spider spin a web and are usually located on the abdomen.

Where do you See Black Widow Spiders?

The black widow spider builds an irregular web in which she hangs upside-down.Webs are constructed in secluded spots such as woodpiles, hollow tree stumps, rodent burrows, overgrown areas and under stones.The spider herself is mostly shy unless defending her eggs, generally avoids light and many times you will not see her but recognize her only by her web.She is much more active at night. In addition to the sites mentioned above, she seems to like man-made structures best: sheds, outdoor privies, meter boxes, drain lines, etc.
