Most rodents don’t require such a large space to gain entry into your home. Even very small gaps can actually allow the rodent in. It is therefore very important to check every part of the building very carefully to be able to spot all entry points that may exist. You need to look at the crawl space vents and even the laundry vents to be able to determine whether there is a problem or not. The doors and windows also have to be checked. The roof area is one of the spaces that the rodents love to use, and so the eaves and the fascia need to be checked very carefully. The rooflines may also have gaps.
If you have a tile roof, you have so many areas that rodents can use to get into the home. The air conditioning chases, the power line entry points and the plumbing stacks are yet other areas that the rodents can use, and so they also need to be checked.
Most rodents can climb and they are pretty excellent at it too. They will follow pipes and walls all the way to the ceiling, and getting in is never a hard thing. When a rodent gets into the house, finding its way within the house and the architectural gaps or cut holes in the plumbing is very easy. The rodents can even get into the home through the toilet and the sewer pipes.
In order to spot the entry point used, you should keep an eye open for chewing. You can also see urine stains as well as droppings through the points that the rodent is using for the purposes of entering the building. Gnaw marks and shavings can tell you the route that the rodents are using. Check this on the casings of the doors, the baseboards, doors and windows.
