Black widow webs can trap mice, they mainly prey on spiders and insects, and their venom is 15 times stronger than rattlesnakes.
The analysis of the claims reveals a variety of outcome: 1) While black widow webs are not typically capable of trapping mice, they are designed to catch insects and small arthropods. There is insufficient evidence to confirm that they can trap mice, leading to a low factScore for this claim. 2) The diet of black widow spiders primarily consists of insects and other small arthropods, which is consistent across multiple sources. This is well-supported, resulting in a high factScore. 3) The claim about black widow venom being 15 times stronger than rattlesnake venom is confirmed by reliable sources, leading to a high factScore.

Black widow webs are strong enough to trap mice.
The evidence from reliable sources such as Orkin and Wikipedia suggests that black widow webs are designed to trap insects and small arthropods but do not support the ability to trap larger animals like mice. The claim is therefore mostly unsupported by the given evidence.
