Denver County, Denver Rat Control Situation:
Wanted to first thank you for the information on your site. A couple of days ago we started to house sit for someone for a couple of weeks. We noticed some evidence of mice the first night we were here and set some traps. Within 15 minutes we caught a mouse behind the stove. We hoped that was the end of it but had our doubts. Sure enough the next morning we heard some running around below the floor boards of the attic which we were sleeping in. We had eight traps set throughout the house but for a couple of days there was no signs or catchings other than a little pitter patter in the morning under the floor boards in the attic. Well just tonight we came back from a day long excursion and sure enough we had another mouse in the trap. We had our concerns though that we may have killed the parents to an unknown number of little mice. Sure enough a few hours later we are hearing little squeeks coming from beneath the floor of the attic. We are not sure how young these little kid mice are but we are curious about what your experiences is in the responses little mice would have when their parents no longer are available to them. We figure the younger they are the more dependent they are on their parents for survival, but what does that mean? We suppose if they are very young they won't survive very long and it may be difficult to get to them before or after their demise. If they are older though, hunger may overcome them and they will start to work their way out of the safe envirenment they have been accostomed to. How long could this process take and even if they do come out would they be up to feasting on the traps? Looking forward to your response Thanks
My response: Jeez, I have no clue. There are probably several adults. The young may starve then die. They'll be so small that they won't cause an odor. You need to seal your house shut to stop the mouse problem entirely.
Denver Rat Control Tip of The Week
Norway Rat Biology
The Norway rat is typically nocturnal. It is a good swimmer; however, unlike the related black rat, it is a poor climber. Norway rats burrow well, and regularly uncover broad tunnel systems.
Rats are equipped for creating ultrasonic vocalizations, both as grown-ups and babies. They may likewise transmit short, high frequency, socially-prompted vocalization during interaction with different rats or animals. This call most takes after a trilling sound but is undetectable to human ears. Rats can discernibly be heard through calls sounding like squeaks when they are in trouble.
These rats are omnivores. This implies they can eat both plants and animals. As predators, rats are opportunistic.
The Norway rat can breed consistently if the conditions are reasonable, and a female can deliver up to twelve litters in a year. The gestation period is just 21 days, and litters can number up to fourteen, albeit smaller litters are common. In this way, the rat population can increase rapidly. Rats have a lifespan of around three years, yet regularly live less than one year.
Norway rats live in enormous hierarchical groups, either in tunnels or subsurface places, such as sewers and basements. When food is hard to come by, the rats lower in the social order are the first to die. If a large portion of a rat populace is eliminated from a zone, the rest will expand their reproductive rate, and rapidly reestablish the old populace level. This makes it imperative to have a plan to get rid of the entire rat population on your property if an infestation occurs.
