Project Zomboid Animal Traps Guide (Build 42.19): Bait, Zones, and Catch Odds

Build 42.19 · trap and bait table values are formula weights, not final catch percentages

How trapping works (two rolls, every hour)

Each in-game hour, baited traps roll for a catch—but only when the trap’s map square is not loaded (you are far enough that the cell has no grid square for that tile). If you stand near the trap and the square stays loaded, the hourly check skips the catch roll entirely.

When a check does run, an animal is eligible only if all of these pass:

1. The trap type is listed for that animal.
2. The bait type is listed for that animal and is still fresh.
3. The current hour is inside the animal’s active window (or the animal has no hour limit).
4. Roll A (trap + bait): chance rises with trap weight + bait weight + (Trapping skill × 1.5).
5. Roll B (zone): chance rises with the zone weight on that square + (Trapping skill × 1.5).

If several animals pass both rolls, the game picks one at random from that list. Place multiple traps and leave them unloaded overnight for reliable food.

Quick start: first working line

1. Get a trap. Loot a Mouse Trap, learn recipes from magazines or auto-learn levels, start with Hiker for Stick/Snare/Crate, or start with Park Ranger for all five craft recipes. The Exposure Survival VHS can also teach the Crate Trap.
2. Place it in a matching zone. Birds and rodents like farms and towns; rabbits, squirrels, and raccoons want forest-type zones.
3. Add fresh bait for the target (right-click → add bait). No bait means no animal check—mouse traps included.
4. Leave until the chunk unloads. Do other work or sleep; camping next to the trap prevents catches.
5. Return after active hours. Closed sprite → check trap. Rebait if empty or broken.

Trap roster (weights are inventory weight, not catch rate)

Trap strength feeds durability and bait-theft checks (higher is more resilient). Destroyed wooden traps often leave scrap wood or nails; cages can leave wire. Keep spares.

Crafting recipes and unlock paths

All five craftable traps must be learned first. Unlock them via hunting magazines, auto-learn thresholds, Park Ranger’s granted recipes, or (for the crate) the Exposure Survival VHS—not by simply “starting with Stick and Crate” on a normal occupation.

• Park Ranger starts with Trapping +1 and is granted all five craft recipes immediately.
• Hiker grants Trapping +1 and immediately teaches Stick Trap, Snare Trap, and Crate Trap.
• Trapping skill books only multiply XP in their level bands; they do not teach trap recipes.

Animals: time windows, zones, and live capture

Build 42 forest zones include birch, farm-forest mixes, and organic forest alongside classic Forest and Deep Forest. Rabbit, squirrel, and raccoon share those weights. Birds and rodents also list FarmLand separately from Farm.

If a live raccoon pull fails, the catch can still fall back to a dead item. Treat raccoons as a Build 42 feature that may keep receiving polish.

Bait tables (attraction weights)

Bait must be a listed item for that animal and still pass the freshness check. Rotten bait fails. Best practical picks below; full lists are longer for birds (many insects and caterpillars share weight 50).

Example line: Cage Trap + Carrots for rabbits overnight in Deep Forest, Trapping 0 → weights 40 + 45 on roll A and 15 on roll B. Raise Trapping to improve both rolls by +1.5 per level.

Checking traps, breakage, and zombies

• Sprite change / closed trap means a catch—right-click to collect.
• Bait can disappear without a catch (theft or decay). Rebait and leave again.
• Traps can break; wooden ones often drop unusable wood or nails. Run several traps so one break does not stop the food loop.
• Caught animals and trap activity can draw attention—do not treat trap lines as silent free food next to an open base door. Fence or place lines where you can clear zombies safely.
• Odd wall/window hoppable spots next to a trap can strip bait and animals; place traps on open ground without those frames.

Rooftop placement can work if the square’s zone types are valid and the chunk unloads, but roofs are not a guaranteed safe or productive setup. Prefer clear forest or farm squares you can defend.

After the catch: food, XP, and skill books

• Dead animals are food items—cook meat before relying on it long-term.
• Trapping XP is awarded when the player who baited/owns the trap collects the animal. Larger catches give more XP (roughly size ÷ 3, with a floor of 3 for corpse items, or 10–20 for successful live removals).
• Only the trap owner gets that XP.
• Trapping skill books speed leveling; Life & Living / VHS can still grant trapping XP or the crate recipe depending on the media—grab books early if you plan a trap-heavy run.

Practical setups that actually work

• Early protein, urban: Looted Mouse Trap + cheese or peanut butter on farm/trailer/town tiles; leave the house and do a loot run.
• Early birds: Stick Trap + bread/worms on farm or town vegetation; all-day window makes daytime checks viable.
• Overnight small game: Crate or Snare + carrots/cabbage at forest edge; sleep 19:00–05:00 away from the line.
• High skill line: Cage Traps (40 trap weight) once Trapping 3 + pliers/wire are available; skill multiplies both rolls.
• Combine systems: Pair traps with farming produce for bait and fishing when you live near water.

Checklist

• Fresh, species-valid bait on every trap—including mouse traps.
• Trap type matches the animal; zone weights favor that animal.
• Nocturnal targets only roll 19:00–05:00.
• Leave until the trap chunk unloads; hovering nearby blocks catches.
• Treat table numbers as weights inside two independent rolls, not final percentages.
• Park Ranger is +1 Trapping with full recipes; Box/Cage/Crate inventory weight is 5.
• Expect raccoons and live rabbits/rodents in Build 42—not just the old five dead-item table.
