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 Far And High Can A Rat Jump?
Jumping is a major part of many animals' survival instincts including rats. But in the case of these small rodents, they have a special way of using this particular survival instinct to their best advantage. One of the most common rats around, which is the brown rat, is known to be able to jump over four feet horizontally or in a downward slope and leap vertically to about 77 centimeters without hurting itself. This clearly shows how high rats can jump and how well they can suspend themselves in the air.
The jumping performance of rats depends mainly on their species because some rats are big while others have lighter bodies which tend to support agile movements. For instance, black rats with lean bodies are known to be able to leap over five feet. While brown rats with large body frames find it quite difficult to leap but do well at jumping downwards.
Another reason why some rats jump better than others is mainly because of their better survival instincts and hunting abilities. Rats in the wild are better at jumping than those in the suburban and urban areas. Therefore, you shouldn't expect the rats in your home to jump or leap that high.
Rats are naturally silent animals and will prefer to move around unnoticed. But in some cases, they make use of their jumping skills. One of the special cases in which they use their jumping skills is when they see a possible threat or a predator. They often use this to propel their speed and get away as soon as they can. Their speed and swift body movements are one of the ways they can stay alive and avoid been eaten by a predator.
