Hennepin County, Minneapolis Rat Control Situation:
Hi, David, Thank you very much to establish your very educational and candid website. I bought a house half a year ago and it had rats in the attic and in the crawl space. I hired a rodent removal guy to take care of the problem. I spent almost $1000 but I still had rats - he didn't seal all the entry points. Anyway, I then did a lot of research in rats. lol. According to my rodent guy, there was about 10 rats living in my attic. But his trap caught none after sealing all the holes (He thought he did but there was two crawl space vent open). He then claimed that all rats gone because they are "scared". Later I set traps myself and I caught two large roof rats (really large, almost 12 oz each I would say). After that, no more caught. In October, I hired an insulation company to remove ALL the batt insulation from my attic. There was still thousands of droppings left on the joist bays. I painstakingly vaccuum them out (me wearing face masks). Now the attic is clean. However, I could not find ANY gnaw marks on wood, nor electric wires, nor on anything else. Why is that? How could it be? This house had tens of thousands of rat droppings in the attic, thousands of droppings in the garage and thousands in the crawl space. But I am not able to spot their damage other than the droppings? I thought rats have to chew on stuffs to keep their teeth from growing too long. I hope you could help answer this question. It always bugs me if there is something unexplainable. Thanks! Guangchi from Minneapolis Area
Minneapolis Rat Control Tip of The Week
How Do Rats Fit In Small Holes, Do They Have Bones?
Rats Can Truly Fit In Small Holes:
A rat needs a space of just about a half an inch to get into an area. Rats have been known to climb through pipes, through areas in the ceiling, and more. Rats can do quite a lot with very little space and this will lead to the chance that they could end up in your home.
Rats Have Joints And Cartilage Like We Do:
The joints and cartilage that rats have can be very similar to the systems that we have. Rats can often work at strengthening their cartilage and joints when they scurry through small spaces. They strengthen their abilities by dashing through small spaces and this ensures that as long as they stay healthy, they can make it through small spaces.
As They Gain Weight They Face Challenges:
As a rat gains weight from staying close to its food source this can lead to the chance that it can no longer fit through holes roughly the size of a quarter. This can make the process of getting into these areas much more challenging. As a rat improves the size of its abdomen, it often loses its ability to fit through tight spaces.
Rats Sense If They Can Fit With Their Whiskers:
Rats are able to fit through areas because their bodies are extremely flexible and cylindrical. The shape of a rat is designed for burrowing and fitting into tight spaces. Rats are able to determine if their body can fit into an area by using their whiskers. This makes every judgment on going through a tight space much easier.
Rats Don't Have Softer Bones:
The skeleton of a rat is just the same as many other rodents. They have hard bones that don't bend and this will often limit the size of the spaces that they can crawl through.
