Best Materials for Long Life

What to Check Before Buying

✅ Wire Thickness

A thicker wire is much stronger and harder for rats to bend.

• Small enough to prevent escape.
• Large enough to allow bait scent to spread.

✅ Door Lock

Choose a trap with:

• Automatic locking

If using outdoors or in damp places, choose:

• Galvanized steel
• Powder-coated steel

• Smooth surfaces
• Rust-resistant finish

✅ Safe Edges

Avoid sharp metal edges that can injure the user.

✅ Handle

A strong carrying handle makes disposal or relocation much easier.

A heavier trap is generally more stable and less likely to be tipped over by a large rat.
