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
Can A Rat Hurt A Human?
Rodents are animals that do not represent a direct threat to people. Although they are intelligent, they do not harm for pleasure. Most of the time, they are just bacteria carriers, but they do not spread them with the intention of starting a pandemic. The cases in which rats have harmed children, might have been because at that moment their instinct was activated to survive. Most houses that are invaded by this urban plague is because they do not take necessary preventive measures and rats have easy access to any corner of the house.
Rats vs. people
Man is surrounded by animals that are predators, so over the years, he decided to protect himself and shelter in homes. Some animals are attracted to find refuge in these homes due to the same necessity of protection and food that humans have. Rodents and people in the same house are a bad combination because of the structural and health damage that rodents can cause.
Can a rat make me sick?
Rats are animals whose excrement, urine, and saliva can contain a great number of bacteria damaging for people's health. Among the most well-known diseases are salmonellosis, leptospirosis, and hepatitis. The most common wounds caused by rodents are bites and scratches. An open and deep wound caused by rodents that come in contact with fluid from a rat will be an open door for microorganisms to spread into the bloodstream causing systemic infections that can be severe and even cause death.
In summary, it can be said that rats can hurt humans through infections by having contact with their fluids or can accidently cause scratches and bites through measures of self-defense. On the other hand, people that have a phobia of these little animals may have psychological damage when coming in contact with them.
