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 To Identify Rat Feces And Where Is It Found?
Dark Brown In Color:
You can recognize the look of rat droppings for their dark brown color. Unlike other animals that have darker feces, rats have a darker brown that does not border upon black.
The Shape:
The shape is often spindle and tapered to be less conspicuous. Most rats have a spindle shape for their feces and the pieces will be no larger than a grain of rice.
The Volume:
Each rat can produce up to 40 droppings in a single evening and this can mean that you are likely to find a series of piles across your home especially if you are facing a larger rat population. As you continue to identify the look of rat feces across your home, you are going to notice piles and likely find rats nearby.
Keep An Eye Out For Rub Marks:
Rub marks are another common sign that you have rats in your home. Rats naturally have grease or dirt on their body and because of their poor eyesight they often leave a series of smudges across your home. The darker marks show areas where the rats are regularly moving throughout your home and potentially entering into areas like the walls. If you started to notice various areas where there could be marks and feces, this offers an excellent chance that you could have a rat inside your home.
Be Careful While Cleaning:
Rats carry a series of diseases and it's very important that you are able to clean up any feces that you find to prevent the chance that a family pet will get into it or that you could be exposed to potential diseases.
