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
Are rats comfortable in cold weather?
As winter arrives, the cold increases, and the consequences of this change in weather are vast. Animals like rats will look to survive during these times. The principal necessity for them to be comfortable in these temperatures include refuge and food.
People's homes are perfect for rats to shelter from the cold. They are designed to give the security and benefits needed for a warm environment. As the cold increases, the rat's muscles start tensing, lowering their immune system to the point of making them more likely to get sick.
People and rats living in the same house are a bad combination
The danger of getting diseases is caused by the accumulation of feces that promotes bacteria development all over the house.
These microorganisms produce very dangerous diseases and infections, among them, the best known for its severity is leptospirosis that is caused by ingesting food contaminated with rodents' urine and feces.
The structural damage that living with rats can cause
Damages caused by rats are attributed by the capacity of their jaws to gnaw. They gnaw on materials like wood, plastic or even cables that, despite being hard, these are not an impediment for their teeth. During colder temperatures, their metabolism needs more energy to stay warm.
Among the activities to obtain this energy are eating and gnawing. On many occasions, this can cause dangerous accidents, such as fires thanks to short circuits caused by bitten cables. Economic losses can range from a pair of shoes to the entire house.
Living together with rodents is harmful for your health and bank account. You should know that when winter arrives, the rain and cold will make them find refuge, so you have to take preventative measures as a defense weapon against this urban plague.
