Montgomery County, Montgomery Rat Control Situation:
David, I hope you can help. My wife and two kids bought our dream house a couple hundred yards from the cliff of the Pacifica ocean here in Moss Beach, CA. I started hearing some scratching in the walls, and began a four month battle with rats that I am losing. I went under the house and there were empty poison containers (from previous owners), thousands of rat poos, and about 20 rat carcasses. I cleaned it all up, and over many, many hours sealed what I believe to be every single tiny nook around the house (I caught a couple rats in the act of going into some holes). We've gone several weeks at a time without any rats, then occassionally we'll hear one. I catch one or two now and then under the house with snap traps, glue traps, but they are small rats, and there are hardly any new poos. Our roof is not accessible to any trees, or anything touching the ground except the water drains. We do have a ton of gopher holes and tunnels all around the house, even right next to the foundation (but none that seem to open up under the house) But currently none of us are sleeping because of one (what sounds like) big rat. It runs around and scratches all night between about 10 pm and 6 am. It is above and around our bedroom (below the kitchen) walls. Sometimes I feel like taking my chances with a pick axe, and blowing open the wall like a madman trying to get that rat. What would be your recommendation? Thank you so much, Marc
Montgomery 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.
