Seal the House

Mice are heading for the gaps in this house. Drag the sealing kit (metal mesh and sealant) onto a glowing gap and hold it there to seal it. You can also tap a gap. Keyboard: arrow keys pick a gap, Enter seals it, B tries poison. Each mouse that gets in adds 2 seconds. Too many inside and you replay the level. The poison button shows what poison does: the mouse gets sick and slow, and the gap stays open.
