⚠️ The #1 Trap Failure: Too Few Traps Most homeowners set 1–2 traps. Professionals set 10–20. The goal is to saturate active areas so every mouse encounters a trap. Think minefield — the more coverage per active area, the faster the problem is solved.

Trap Placement Rules

Perpendicular to the wall, trigger end touching the wall

Mice run along walls using their whiskers for navigation. They WILL run into a perpendicular trap. They avoid a parallel trap or one in open space. This single rule explains 80% of failed trapping programs.

Every 2–3 feet along active walls

Place traps every 2–3 feet along every wall in an active area. Yes — 8–12 traps in a single room. Increase density near droppings, gnaw marks, and visible runways.

Double up in runways

Place two traps side by side facing opposite directions in any active runway. A mouse jumping over the first lands on the second. Dramatically increases catch rate in confirmed runways.

Priority locations

Behind the refrigerator (always), inside cabinets under the sink, behind the stove, in the attic along top plates, in the basement along foundation walls, inside the void behind the dishwasher.

Best Bait

🥜

Peanut Butter (Best)

Most effective mouse trap bait. Use a pea-sized amount — the stickiness forces the mouse to work the trigger, ensuring a clean kill. Creamy slightly outperforms chunky. Reapply every 3–5 days as it dries out.

🍫

Hazelnut Spread (Excellent)

Nutella or similar products sometimes outperform peanut butter. The fat + sugar combination is highly attractive. Excellent alternative when mice seem to be avoiding peanut butter traps.

🧵

Nesting Material (Underrated)

In fall and winter, mice actively seek nesting material. Tie a small piece of cotton ball or dental floss to the trigger. Mice working to free it trigger the trap — excellent for trap-shy individuals.

💡 The Pre-Baiting Trick for Norway Rats Norway rats have "neophobia" — fear of new objects. Set unloaded traps baited with food for 3–5 nights before arming them. Once rats are comfortable eating from the trap, arm it. Catch rates increase dramatically with this technique.

⚠️ Hantavirus Precaution Deer mice carry hantavirus. In areas west of the Mississippi, always wear gloves and a dust mask when handling traps. Spray droppings with 10% bleach solution before cleaning — never sweep dry droppings.
