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

Can Rats Kill Mice?
Before providing an answer to this question, first of all, you need to be able to differentiate between a rat and mouse. As you must already know, they are both rodents and are quite identical. Without precisely knowing the differences between these two rodents, it will be quite difficult to know how they relate with each other and if rats do kill mice or it's just another myth.
To help you understand this in the best possible way, we will be taking a look at some of the qualities possessed by both rodents. After which we will address the main topic which is whether rats are capable of killing mice or not.
Rats
Rats are medium sized rodents with sizes bigger than that of mice. They have long tails and are very active compared to mice. The most common household rat is the black rat and this particular specie of rat is bigger than mice and also very active.
Mice
On the other hand, mice are smaller rodents with a pointed snout and small round eyes. These rodents have uniform traits; hence they often tend to look very identical. They are very docile when compared to their rat counterparts.
Having shared all these, by now you should categorically be able to differentiate between rats and mice. Coming back to the question above, the fact is rats are capable of killing mice. This habit is only exhibited when rats are faced with starvation and the only option left is to kill and feed on them.
Also, a change in environmental conditions can trigger their hunting senses and make them kill mice. Apart from any of these conditions, rats killing mice doesn't usually occur. You might have rats and mice in your home at the same time causing a nuisance.
