How can you get rid of roof rats?

There are a few ways you can get rid of your roof rat problem. The best ways are by baiting or setting traps. Both of these can be very effective and can be done economically.

Baiting involves laying rodenticide down for the rats to eat which will poison them and kill them. This can be very effective but is not the best choice for dealing with roof rats. This is because although the rats will likely die from the poison they will still be inside your house, and you cannot control where they go to die. This leads to rat carcasses being left in your house in places you do not know or cannot reach. You do not want this in your house as the carcasses can rot and cause further health and building damage. Only use baiting when the rats are outside of your house or you can regularly check for dead rats. Keep in mind interrupting the rats often will stop them eating the poison.

Trapping is the best way to get rid of roof rats. This can also include using bait but it also captures the rat, making sure they do not wander away to die. You can also use other traps to kill your roof rats.

Conventional snap traps can be effective - these are like the classic mouse trap with a metal bar that kills the rat. This can work, but each trap can only kill one rat before needing to be reset, so this is not the best option. Modern electronic rat traps are a good option. These kill rats with an electrical jolt, and can be used many times. These are only suitable for inside use when there is no risk of other animals being caught.

Electrical traps are also more hygienic as there is no blood from the rat. Yet another option to try is glue traps, which catch rats that run across the trap using glue. This can let you remove the rat and release it elsewhere if you wish to as it will not kill the rat. A final option is using ultrasound devices that deter rats from entering or using an area.

What is the best way to get rid of roof rats?

Of the options above, the best way to get rid of roof rats is using traps, and specifically electronic rat traps.

These will kill rats quickly and humanely, as well as doing it in the most hygienic way that prevents the rats dying in undesirable places. You will need a number of these traps to stop your roof rat problem, but as these traps are reusable this can be seen as an investment. It is also much cheaper than medical care for your family or pets, and cheaper than costly building repairs roof rats can cause.

Electronic rat traps are the best way to get rid of roof rats, with other trapping methods being the second choice. Baiting is not appropriate for these pests.
