Contra Costa County, Richmond Rat Control Situation:
Hello!!! I was just at your website, and thought I would throw an email your way... I went into my garage tonight, and was throwing a load of laundry into the washer, and I heard scratching coming from the wall in the far right hand corner of the garage... I went over to inspect, and couldn't see anything, but the scratching continued... I tapped on the wall with a broom, and the scratching stopped... My question to you is this- if it were to be a mouse would I be able to hear them so clearly scratching? I know they don't weigh a whole lot... We did have a problem with squirrels in the attic a couple of months ago, but we got rid of them, and blocked the entry way that they made to enter the attic... We checked outside this evening after we heard the scratching, and cannot find any entry points in the eaves, soffits, etc... So I am under the impression that its not squirrels or something large like that (praying that its not)... I hope I have made sense... I am a nervous wreck right now at just the thought that their is something in my wall =( I hope to hear back from you soon... Joni
My response: Sometimes mice can make very loud noises, if they scratch directly on the drywall. But squirrels, opossums, raccoons, and rats also get in wall frequently.
Richmond 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.
