Pros: Low maintenance — not necessary to check for dead rats, as the rats will leave the trap and die elsewhere. Can be left out semi-permanently if poison is consistently refilled. These traits make poison traps good choices for outdoor rat control.
The best rat trap to catch rats depends entirely on where the trap is to be placed.  Indoor rat trapping is much different than outdoor trapping.  In order to determine which rat trap is best, knowing all of the different styles and methods helps.  Never place an old wooden snap style rat trap where children or pets can get to it.  By comparison, glue board style rat traps can’t be used outdoors.  Outdoor trapping can be difficult, indoor trapping dangerous for children and pets.  What do the pros do?  Which rat trap is best?
Dog poop is not at the top of the list of preferred foods for rats. It may eat it if there is no other food available, but I agree it will have a tendency to encourage them in contrast to repelling them. In addition, dog poop is not very hygenic to have about the place. Have you tried contacting your local authority to see if they have any policies in place relating to this issue?
If you prefer the traditional style traps with a little more strength, then the Made2Catch Classic Metal Rat Trap may be what you’re looking for. These traps have an all metal design that is strong and will last a lifetime. Made from galvanized steel, they can be washed and reused over and over again. The paddle design is heavy duty and combined with the powerful spring action; there’s no rodent getting loose from its grip. These little mechanisms are very effective for keeping vermin under control. This specific unit is 4.5 ounces and 6.6 x 3.5 x 0.9 inches in size; it is especially for rats and other larger rodents. While it will get rats, it is not able to get squirrels or other creatures found in attic spaces.

To make a homemade rat trap from a bucket, you will also need a box, thin board, long wood plank, water and bait food. Take or buy the buckets of at least two feet in size and fill it half full with cold water.
Some people prefer to choose rat exterminator companies when they have to deal with rat infestation. However, not everyone can afford this option. Buying special traps is often the way out. You can choose snap traps with effective trigger system or purchase live and electronic traps for safe and humane rat control. It’s up to you what choose.
I think I will try the bucket rat trap with stairway to heaven, but made the spindle withe the can on an inch or so lower. My reasoning is that if it’s too high they could just eat away, but lower down they would need to lean in more and hopefully fall in more easily
Use a hydrogen peroxide topical solution (available at most drug stores) and an old toothbrush to clean the inside of the chamber. If needed, use a wire brush to remove any corrosion, being careful not to be too vigorous. This could accidentally remove all of the protective zinc plating.
The liter bottle trap is promising; Cut a plastic soda bottle 3/4 of the way up and invert the top spout into the base. Secure it with glue or tape and put bait such as peanuts or seed in the hole so it drops to the bottom. Grease the funnel with cooking oil or butter so the mouse gets no grip. Place the trap near a shelf or something so the mouse can jump or climb to the inverted top. Once in the funnel the only way is down, he won’t be able to climb out and you can release him to a safe place. This trap is also useful in that it can double as a fruit fly or gnat trap.
I know this is an old post, but you actually want the stairway to heaven in line with the wire. The vermin will attempt to high wire in an effort to get to the bait. If it doesn’t make it to the can, it loses its balance and will try to gain foot on the can. Then it’s bye bye Ratzilla!
Set the trap close to where you want to place it, such as in a cupboard. Apply an attractant to the metal bait trigger. Position the pin away from the trap and carefully pull the spring-loaded U-shaped metal bar back to the opposite end and hold the bar firmly with one hand. With the other hand, place the metal pin over the U-shaped bar and insert the curved end of the pin into the left slot of the bait trigger.
To keep unwelcome “visitors” out, seal entry points using foam sealant, steel wool, hardware cloth, or metal flashing. If any animals need to be removed from homes, this can be done by using humane box traps, like the one pictured here:
One of the cruelest methods of killing animals that exists today is the glue trap. These devices consist of pieces of cardboard, fiberboard, or plastic coated with a sticky adhesive designed to ensnare any small animal who wanders across or lands on its surface.
Obtain a large coffee can. The can should have a mouth approximately five to six inches across and a height of about seven to eight inches. The coffee can should have smooth sides which cannot be easily scaled by rodents. If using economy size coffee cans which are ten inches deep or more, place a small pad or bunched cloth at the bottom to prevent injury to the mouse you’ll catch.
Up until 1996, more than 4,400 trap patents were issued, more than ninety-five percent of these being awarded to amateur inventors, which truly makes the trap a consumer’s invention in most every shape and type possible, electric or not.

If you plan on using plastic snap traps indoors, it is best to use them in a box with holes cut out on the sides or inside a rodent bait station.  This is purely for safety reasons.  Plastic rat traps are one of the safest and effective traps on the market.  Safe enough in my opinion to use around older children and pets.
The rat, enticed into the box by a yummy treat at the entrance and smeared on the back wall , steps on a metal plate.  This triggers an electric shock which – as long as the batteries are full or nearly full – kills within a couple of seconds.
But you’d better know that sticky rodent traps are inhumane, because trapped animals usually suffer and cry for many hours before death from dehydration or stress. So we suggest you check your glue traps very often or use other traps.

Insert a third skewer, half as long as the first two, into the end of the bottle (the base the bottle would stand on in a standard vertical orientation). Stick a piece of cheese on the end of the skewer which is inside the bottle.

Electronic traps are quick, safe to use and are a very humane way to kill a rat. They are also highly effective but also highest priced rat traps available. They also must be checked regularly, but the best ones have a warning light to let you know that a rat has been caught. You can check it from a distance, and if the light is on, you can empty the trap. However, like all stationary rat traps, be careful that the rats don’t become trap wary. You may want to move the trap to a different location after every successful kill.
Remove the paper label. Use you’re ice pick or drill to bore a hole in the center of the can lid. If you plan to reuse the liquid, turn the can over and bore another hole in the bottom of the can over a container. This will vent the can and empty in a few minutes.
Obtain a long cardboard tube with one end closed. The tube might be from a paper towel roll or poster. It should be at least 12 inches long, 2-5 inches in diameter at its mouth, and have one end stopped with tape or with a cap. Place something soft in the closed end such as cotton balls or a wad of soft fabric.

Once when I was a kid, my dad used a glue trap to catch a mouse in our basement. The result was so awful for the mouse that my mom and I made him promise to never use that kind of trap again. Call me a softy, but I’m a firm believer that you don’t have to kill pests to get rid of them.
