Los Angeles County, Los Angeles Rat Control Situation:
Hi David, I'm in southern California. I have at least one rat in my ceiling, maybe two or more. I've read your website and really appreciate the great insight you're providing. Based on your advice, I've caught 3 rats around the outside my house (over the last 2 months), trimmed trees back (3 days ago), and plugged all the access holes I could identify (3 weeks ago).
Yet I still have at least one rat in my attic. Though I've place several snap traps (baited with peanut butter and bird seed) in the attic, I get no nibbles. I also cannot find any evidence of their paths. I've moved the trap several time with no success. From inside the house, I hear them in sections of the attic (about 3:00 am) that are completely inaccessible to me (because of firewalls.)
So I hired a pest extermination company. For $275 they put some poison bait stations outside, and three snap traps in the attic that are baited with a beef jerkey substance. The traps are near the attic access panel - not near the rat noise activity. The guy's reply was that the scent would lure them. He also reviewed my hole-plugging and said it was fine. He didn't get onto my roof. It's been three days and I check the snap traps in the morning and around dusk each night.
My questions are:
1. Is it safe to assume that the rat(s) sleep in my house during the day and at night they are coming and going outside? Does this mean I've missed an access point?
2. Considering the inaccessibility, is it common to drill a hole in the ceiling (like a 4" hole for recessed lighting) to place traps in the attic for those inaccessible places? If I drill a hole, then I can stick a camera up there and take pictures to look for evidence, place the traps, monitor them, etc. But then I've got a hole to deal with.
3. Is it worth parking myself on the roof and patiently waiting to see where the rats are coming and going?
4. Have I given the beef jerkey snap-traps enough time to do their thing? Any other advice? Thanks for your help!
Los Angeles Rat Control Tip of The Week
How Do Rats Fit In Small Holes, Do They Have Bones?
Rats Can Truly Fit In Small Holes:
A rat needs a space of just about a half an inch to get into an area. Rats have been known to climb through pipes, through areas in the ceiling, and more. Rats can do quite a lot with very little space and this will lead to the chance that they could end up in your home.
Rats Have Joints And Cartilage Like We Do:
The joints and cartilage that rats have can be very similar to the systems that we have. Rats can often work at strengthening their cartilage and joints when they scurry through small spaces. They strengthen their abilities by dashing through small spaces and this ensures that as long as they stay healthy, they can make it through small spaces.
As They Gain Weight They Face Challenges:
As a rat gains weight from staying close to its food source this can lead to the chance that it can no longer fit through holes roughly the size of a quarter. This can make the process of getting into these areas much more challenging. As a rat improves the size of its abdomen, it often loses its ability to fit through tight spaces.
Rats Sense If They Can Fit With Their Whiskers:
Rats are able to fit through areas because their bodies are extremely flexible and cylindrical. The shape of a rat is designed for burrowing and fitting into tight spaces. Rats are able to determine if their body can fit into an area by using their whiskers. This makes every judgment on going through a tight space much easier.
Rats Don't Have Softer Bones:
The skeleton of a rat is just the same as many other rodents. They have hard bones that don't bend and this will often limit the size of the spaces that they can crawl through.
