Rat traps may be use in the yard and inside buildings with good results. Wood snap traps are inexpensive, give positive results, and eliminate the possibility of a poisoned rat dying in an inaccessible area. Rat carcasses within a structure can cause serious odor and fly problems.
6 Simple Steps to Safely Set a Snap-Trap can be found here.
Several traps may be set at once for maximum effectiveness.
For best results, try several different baits to see which is accepted most frequently by rodents. If fresh food is abundant for the rodents, use a bait somewhat different than what is available to them.
These baits should be kept in fresh condition for best results and should be securely fastened to the trigger.
Traps should be placed along known rat runways such as fence tops and walls, where rat activity is evident. Securely anchor traps to an immovable object to keep any trapped animals at the placement site.
- Adjusting Snap Traps
Before baiting the trap, check for sensitivity of the trigger. The trap should be sensitive enough to snap closed when the rodent feeds or otherwise touches the baited trigger, but not so sensitive as to snap if roaches or other insects come in contact with it. Trigger sensitivity can be checked by lightly touching the trigger of a set trap with a screwdriver. If the trap does not snap, the metal trigger tab can be bent outward to make it more sensitive. If the trap is too sensitive, the trigger tap can be bent inward.
- Setting a Snap Trap
To set a snap trap, apply recommended bait to the trigger. Pull back the bail with your thumbs. Hold the bail in place with one thumb while attaching the bar to the trigger tab. Carefully place the trap as recommended in the diagrams. Better results are usually obtained if two traps are set side-by-side. Please note: If placing the trap along the wall, be sure to place the trigger of the trap perpendicular to the wall.
- Prebaiting Traps
It is also a good idea to prebait, which is to use a baited but unset trap, so that the rodent can become familiar with and start feeding on the baited trap. This requires only two or three days, after which the traps can be set. The following baits are most attractive to rats: Peanut butter on steel wool, dried meats, cheese and tomatoes.
- Maintaining Traps
The working parts of the trap should be oiled occasionally using mineral oil, never petroleum based oils. Petroleum oils may act as a repellent to rodents. Never store traps near insecticides or other chemicals, or handle domestic animals or pets before setting out traps. These can also cause traps to take on a repellent odor.
Proper disposal of rat carcass
Using a plastic bag, place your hand in the bag like a glove, pick up the carcass with the bag, invert the bag or turn bag inside out, tie a knot at the end of the bag, and dispose of rat in a trash container with a secure lid.
