If not, is there a verse that similarly encapsulates this notion?
“An idle mind is the devil’s workshop and idle hands his tools.” Adage
Proverbs 18:9 [ESV] Whoever is slack in his work is a brother to him who destroys. [Heb. - Moreover one-being-slack in-work-of-him brother he to-Ba'al (l-bol), one-(bringing)-ruin/corruption (mshchith).

Says George S. Hilliard: The ruin of most men dates from some vacant hour. Occupation is the armor of the soul, and the train of idleness is borne up by all the vices. I remember a satirical poem in which the devil is represented as fishing for men and adapting his bait to the taste and temperament of his prey; but the idler, he said, pleased him most, because he bit the naked hook.

Question: "Is ‘idle hands are the devil’s workshop’ a biblical statement?"
Answer: Though the statement is not found verbatim in the Bible, “idle hands are the devil’s workshop” has its roots in Scripture. The apostle Paul notes that those who waste their time in idleness or in a non-productive manner are easily led into sin: “We hear that some among you are idle. They are not busy; they are busybodies” (2 Thessalonians 3:11). By not using their time productively, these people were tempted to meddle in other people’s business and stand in the way of their progress. “They get into the habit of being idle and going about from house to house. And not only do they become idlers, but also gossips and busybodies, saying things they ought not to” (1 Timothy 5:13). These idlers and busybodies were wasting time that could have been used to help others. In essence, their lack of activity was leading them into sin.
Idleness is not the same as rest. The Bible advises people to rest, and taking breaks from work is good. By “idle” we mean “lazy” or “doing nothing when you should be doing something.” Idleness often stems from not having a specific goal or purpose in mind. With no goal, one can be easily distracted. The book of Proverbs warns us that sloppy or careless work is akin to malicious destruction: “One who is slack in his work is brother to one who destroys” (Proverbs 18:9).
We live in a sinful world, and a person who doesn’t have something particular to do will invariably be tempted to do something sinful. If we have nothing to do, the devil is all too eager to find things to occupy our time.
‘An idle mind is the devil’s workshop’ is one of the many variants of the proverb ‘the devil makes work for idle hands to do’. The is a very old idea and, as it can be dated back at least as far as the 4th century theologian St. Jerome, it can be said to be one of the oldest expressions in the English language. Jerome’s version was ‘Do something, so that the devil may always find you busy.’...
