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
What Are The Different Sounds Rats Make When They Are In Your Home?
The sound of chittering is often the sound of a rat chomping or grinding their teeth against building materials in your home. This type of behavior is fairly common for rats to sharpen their teeth as well as for nest construction. If you find that a rat in your home is making a chittering noise, this could be an indication that they are building a nest and ready to have children.
Hissing noise is often the sound of a rat in danger or a rat that is angry. Rats can be extremely territorial and if they are in an area of another rat that has a nest or they encounter a family pet there's a chance that they could hiss. If you approach a rat and hear a hissing sound, a rat could be simply trying to assert its dominance over you.
Squeaking is often a communication method that is used between rats. The process of squeaking is fairly common in mice as well as in rats. The squeaking sound can be an indication that a rat is content and it is also a fairly common way to identify rats that could be in the walls or in close areas to your location. It's often difficult to hear a squeaking sound but if you have several rats in your home it can be easier to pick up as they start to move through the walls.
Rustling sounds are often the process of nest construction and these can happen outside the home or inside the home as a rat drags materials to build a nest. If you notice the sound of rustling, it is crucial that you consider contacting a pest professional as you could be facing rats that are reproducing.
