Pima County, Tucson Rat Control Situation:
David, Can you please help me with some advise and maybe a referral for a local professional in Tucson AZ? I live in a mobile home and hear rats in the walls and ceiling at different time including during the night. I had a professional general contractor put very fine metal chicken wire called "hardware cloth" all around the bottom of my mobile from the edge to the ground attached to the stackered white bricks with screw drilled into them. There might be some very small gaps in different places, but no sign of rats getting in like black marks from their fur, rat droppings or urine stains any where outside. I even put screening around the the very small roof vents. I also previously had a friend come by who is in the pest control business and he looked all around the outside and just could not find where the rats are coming in at. I was using Decon for about 7 or 8 months, but now switched to a very strong blocks of rat poison from a local Do-it-Yourself Pest Control store. I always put the poison out under a small hole under the very fine metal hardware cloth in two different places and then block the hole off with a brick. I bought a 9 pound bucket for $39 and they already ate about 2 1/2 to nearly 3 pounds of it and I am still hearing them. *** Why is the strong blocks of poison not working, do they get amunity to it? Last year I even brought Rid-Ex Plus that turns your whole house wiring into a sound they do not like. It worked for a while, but not does not seem to affect them at all. It comes on for 3 minutes and then shuts of for 3 minutes (so they do not get use to the sound waves) and keeps repeating the cycle 24 hours a day 7 days a week.
How in the rats world are they still getting in my walls and ceilings voids? Can the rats be possibly tunneling or travleing through the underground the sewer pipes? *** Why is the strong poison not working? Do the rats get amunity to it after eating it for awhile? *** If there are dozens of them, would I not at least see one outside once in awhile or some signs of them? Where is there food supply? A few doors down are a few fruit trees, but would they not move closer to them? A tree right next to my place has these really small berries, could that be what they are eating? Should I move out for a while and not use any air conditioning, so the walls will get to hot for them to live in? I am at wits end and really need your advise and/or a professional to probably come out and help me get rid of these rats.
Tucson 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.
