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!

Can Rats In An Attic Destroy The Insulation?
If you have rats in your attic, one of the things you need to be concerned about the most is your insulation because these rodents are capable of destroying the insulation of your home. Being the major part of your roof that helps to absorb the heat coming from outside and prevent it from escaping into your home, you can't afford to keep having those rats nesting in your attic.
Maybe you are wondering what the rats in your attic have to do with your insulation to the point of destroying it? Right here, we will be enlightening you on how the activities of rats in your attic can destroy the insulation of your roof.
The first reason why rats will seek out to destroy the insulation in the roof is that the soft material of the insulation is good nesting material. As a result of this, they will continuously tear the insulation, remove the materials, and then use it to build their nest in the attic.
If the rats are not removed from your attic quickly, they will multiply in number and that will increase the rate at which they tear and remove material from the insulation in your roof, leaving the insulation void.
Apart from the physical damages that rats cause to insulation, these rodents use the materials of the insulation as latrines, which usually causes stains on the surface of the insulation. When this accumulates over time, the dusty particles of the feces on the surface of the insulation will begin to escape into your house and begin to cause several airborne diseases.
Having shared this, you need not waste any more time to get rid of the rats in your attic. If you don't swing into action quickly, the damage they can cause will cost you more than you ever expected.
