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
Are Mice or Rats Easier to Trap?
Intelligence:
Mice can often be much easier to trap because they are naturally curious creatures. It often takes just one or two days to capture a mouse after setting up a mousetrap. If you're having difficulty trapping a mouse you could consider moving it to a different location. Rats can be extremely intelligent and they communicate with each other meaning that any new objects will often bring about suspicion.
Reproduction:
Rats often reproduce at a much faster rate and this can make it difficult to control a rat problem if it's been going on for a long time. Most mice have around eight litters per year with around 5 to 6 pups in each litter. Rats can have between 6 to 12 pups in their litter.
Diet:
Rats can often be ravenous eaters and often require meat or a more substantial food source in order to remain satisfied. This can often make rats very difficult to trap because they can be so fussy about their food.
Size:
Rats have a definite size advantage over mice and this often means using much larger traps and some extra measures when it comes to keeping them in a trap. Because of the extra costs of these larger traps and the need to be more careful with where you set them, the requirements to trap a rat can be considerably higher than what it takes to trap the average mouse. Most rats can reach a length of between 7-10 inches and weigh up to a pound whereas the typical house mouse maxes out around 8 inches including its tail.
Tracking:
It's often easier to track rats because they leave larger footprints and they can cause a bit more destruction with their added size and strength. This can make finding rats throughout your home a bit easier.
