1. Be Proactive

Be aware of the rat prevention methods that currently exist so that when a rat infestation does occur, you’re prepared. Just by researching rat infestation prevention methods as you are now, you are being proactive. 

Actively consider the proceeding steps and precautions, even when there aren’t rats present. If your home or property has a history of rats, make sure you always have the necessary tools on hand.

2. Remove Current Occupants

Before you can block anything off, you need to get any rats currently inside out. There are two standard tools for this: bait stations and snap traps. 

When placing the baits and traps, look for any current paths rats seem to use. Look for tooth marks and droppings. If you have pets or children, make sure the traps or baits you choose are safe and out-of-reach.

3. Seal Up Holes Inside and Outside the Home

First, you should target any holes inside and outside your house that you know rats are using. Steel wool, lath screen, and rodent block are all efficient materials to seal these holes.

After the obvious holes are sealed, examine every other opening across the interior and exterior of your home. Consider decks, doors, vents, fireplaces, cabinets, pipes, crawl spaces, and everything else a rat may utilize. Once they’ve been inside once, they’ll want inside again.

4. Clean Up Rodent Food Sources and Nesting Sites

Examine the exterior of your property to make sure you have nothing that’s encouraging a rat infestation. First, examine any immediate food sources, such as trash, a garden, or fallen fruit. 

Study your property for any place that may serve as a home to rodents, such as piles of wood, debris, and bushes. Trim bushes and plants if necessary and remove any debris that you can.

5. Set Traps

Reviewing Step 2, if necessary, place more traps and bait stations inside and outside your home. Place these near spots rats have come through before.

6. Remove Outdoor Food Sources

Bird feeders, fruit trees, and gardens are very good at luring unwanted pests. While most bird feeders are easy to put away, trees and gardens are much more difficult to part with.

Pick up any fruits that fall from your trees as soon as you see them. For gardens, immediately remove all fresh and rotting vegetables. Consider planting mint, which emits a scent that keeps away rats and mice. Consider using a “predator urine” spray on your garden if the rat infestation persists.

7. Build a Wall

Build a barrier around your home or whatever spot the rats are infesting your building. Using cement, crushed rock, or another material that would be too heavy for rodents, build a barricade not larger than a foot or two.

8. Pick Up a New Friend From Your Local Shelter

Pets, particularly cats, are a great way to keep rats and mice away. Even if your cat isn’t the most skilled hunter, many rodents will recognize them as predators anyway and decide to infest the next house instead. Dogs are also efficient at scaring pests, though whether or not a rat perceives your dog as a threat is up to the rat.

9. Contact Hama Pest Control

Rat infestations can be a lot to handle. Fortunately, any infestation can be taken care of by Hama Pest Control, the chief expert on pest control services and rat poison in Canada.

What Are the Warning Signs of a Rat Infestation?

The clearest warning sign of a rat infestation is personally seeing or hearing a rat. Seeing just one rat could mean there are more rats you don’t see, even if you only ever see the one. 

Look for any food scattered across your property. Rats particularly like citrus fruits, such as lemons and oranges, on which they leave very distinguishable bite marks. They may also leave bite marks in any food items in or around your trash.

Finally, if you have pets, your furry friends may be more aware of the rat infestation than you are. Look for any indications of your cat or dog being on alert. If they’re sniffing or guarding one specific area, it may indicate rats have been there.
