To catch INTPs, you have to lay out bait. As an INTP, you should have an idea of what they might find enjoyable like an inconclusive thesis on why paint drying is a productive way to entertain oneself. But never give them the entire thesis. Lay an erratic bait trail one page at a time until you lead them to the facade of a gingerbread house. Leave the door open so they can see that it's actually a library full of inconclusive tomes of the unusual or incidentals. This will lull them into a sense of security enough to step inside. Once they've crossed the threshold, lock the door behind them. They're pretty low maintenance since food and water aren't of major interest but they will need to be replaced often due to shorter life spans.
Much luck in your hunting and welcome to TypeC!
