A pest control company charges $40-80 per month for rodent management. The bait they set is brodifacoum — a second-generation anticoagulant that kills the mouse over three to five days. During those days, the dying mouse becomes easy prey for the owl, the hawk, the fox, and your neighbor's cat. The poison moves up. The company comes back monthly.

Four animals were running rodent control on your property before the bait station arrived. The poison you hired killed them too.

The barn owl hunts by sound alone — her asymmetric ears triangulate a mouse under grass in total darkness. A single family removes over 3,000 rodents per year. Cost per rodent: functionally zero. The bait station costs $8.11 per rodent.

The red-tailed hawk works the day shift from your fence post. Her diet is 85 percent small mammals. She produces zero secondary poisoning.

The rat snake works the interior — your barn, your walls, your crawl space. She goes where bait stations can't.

The red fox pounces through grass at dawn, aligning her strikes with Earth's magnetic field. She removes 3,000 to 4,000 rodents per year.

The pest company replaced a team of four. The replacement killed the original staff. The mice came back. The invoice didn't stop.
