The House Arrest is a universal in-house sparrow trap that mounts directly inside any nest box with a flat wooden front and an oval, slot, or round entrance, placing a passive live capture system precisely where House Sparrows are most vulnerable — at the nest they're actively defending. A 3-inch tripper wire set in the capture position waits silently until a sparrow enters and triggers the mechanism, securing the bird without bait, without external setup, and without alerting the rest of the colony. Compatible with front, back, and side opening nest boxes across a wide range of entrance configurations, The House Arrest is the in-house counterpart to an external bait trap — covering the capture scenario that external traps can't reach. Mounting template, instructions, and screws included.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eScientific Engineering\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eIn-House Passive Capture:\u003c\/strong\u003e Unlike external bait traps that require open placement and active baiting, The House Arrest operates from inside the nest box itself — placing the capture mechanism at the precise location where a territorial House Sparrow is most likely to be present and least likely to be on alert.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e3\" Tripper Wire Mechanism:\u003c\/strong\u003e A tripper wire extending 3 inches back in the set position captures sparrows upon entry without requiring bait, visual attractants, or landlord presence — a fully passive system that works continuously once installed and set.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eUniversal Nest Box Compatibility:\u003c\/strong\u003e Designed for any nest box with a flat wooden front and oval, slot, or round entrance openings — compatible with front, back, and side opening configurations across the full range of standard cavity nesting box designs.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSlot Opening Compatibility:\u003c\/strong\u003e Compatible with slot openings up to 3.5\" wide.
