Rats are extremely smart. So before you try to trap rats outside, you need the best techniques that don’t teach rats to avoid your traps. Luckily, you found the page that has your answers here.
Trapping Rats Outdoors
Traps should always be part of a good IPM strategy for rat control in the garden & at home. But there is a right and wrong way to do it.
How to Trap a Rat Outside
Humans have designed thousands of different rat traps over five centuries. There’s the reliable string-and-a-5-gallon bucket trap. There are fancy new electronic rat zappers. Some catch multiple rodents at once.
But none have been the silver-bullet. Unfortunately, rats are so smart they will learn to avoid traps over time if they notice other rats trapped.
Specifically, they are able to associate the smell of the bait and feel of the trap with danger.
For this reason, trapping rats outside should be done in a way that doesn’t teach your neighborhood rats to avoid traps.
What is the best rat trap?
The best rat trap style is a classic snap trap. Some trusted brands used by professionals are Victor, Jawz, Catchmaster & T-rex. Choose cheaper traps, so you can set more of them. The exact style of snap trap won’t matter as much as following the techniques below:
The Best Way to Catch Rats Outside
Mass trapping: set 1 enclosed trap per 15′ linear feet of fence line, under sheds, decks, shrubs, and any other area where rats are active outside. 6-12 traps is great for a typical Portland rat control job. The more the better.
How to Get Rid of Rats Outside when You Have Dogs
Traps must be enclosed and secured to avoid injuring dogs, squirrels, birds, raccoons, cats, skunks or opossums. Cut 2 golf-ball sized holes in a sturdy cardboard box and stake it down over the trap, or use an overturned milk crate weighted down with a concrete block to enclose traps from wildlife & pets.
Best Bait for Rat Traps
Use a variety of bait types. Do not overload the trigger paddle with bait, 1/8 tsp of bait is plenty. To choose the best bait to trap rats outside;
Think of what the rats outside might already be eating. Are there figs or persimmons ripening and falling? Or does your neighbor feed squirrels peanuts? Your traps will work great if the rats are already comfortable with the bait you’re using.
In general high-calorie, fattening or protein rich foods like candy, chocolate, bacon, granola bars, almond butter, jam, and canned meats make excellent rodent baits.
Avoid junk foods with excessive preservatives and additives, rats may be able to smell and avoid them.
Wear gloves and take care not to contaminate the bait or traps with your body oils, tobacco smoke or other foreign smells.

How to Catch a Smart Rat that Avoids Traps
Most importantly, think of a bait type that your neighbors probably haven’t used already. Peanut butter in particular should be avoided. Because it is so widely used, the likelihood rats have already associated the smell of it with danger is greater.
Lastly, male vs. female and pregnant vs. juvenile rats have different nutritional requirements, so use both fats and protein baits in different traps or combined.
Best Way to Kill Rats Outside
Traps should be checked often. You need to remove captures as soon as possible. Then replace your traps with a different trap style, bait type, and bait station after every capture. These steps can deter rats from learning that the trap style, bait type and bait station are dangerous to them
If your rat traps outdoors aren’t catching rats anymore, assume the rats have caught on to you. Remove equipment for a minimum of 2-3 weeks. Try using a repellent product to disrupt rat behavior temporarily.
Anticipate they will catch on at some point. Avoid running more than 1-2 rounds of outdoor rat mass trapping per year to prevent teaching rats to avoid traps.
What Controls Rats Naturally?
Rats that do not succumb to the natural environment after about 2 months have 7-14 babies, and the rat issue worsens exponentially.
How to Control Rats without Poison
If we want to control rats outdoors without poisons, we need to prevent them from running around and breeding out of control. There is basically no other way.
- Eliminate any possible food source for rodents;
- Although feeding birds & wildlife is a common household pastime, bird seed often attracts rats and mice.
- Chicken coops should be enclosed on all sides including a floor, with quarter inch galvanized steel mesh, and allow no gaps for rodent entry. Feed should be placed inside a mouse and rodent proof coop.
- Compost bins should also be enclosed on all sides, including bottom.
- Harvest garden veggies and fruits regularly, and remove fallen tree nuts and fruits.
- Enclose food storage, pet kibbles & fertilizers in the basement, shed or garage in air tight containers.
- Reduce vegetation wherever possible, particularly within a foot or two of the ground, sides of buildings & along fence lines where mice & rodents like to hide.
- Eliminate yard debris, wood storage & unused masonry to control rodent & pest harborage.
- Inspect your home, garage & outbuildings regularly and seal any gaps and areas where rodent damage appears.
- Fill any burrows found with small diameter pea gravel, and keep some on hand for when it opens back up again.
