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
What Are Possible Diseases Rats Can Carry?
Apart from causing severe damage to the structure of houses, rats are major carriers of life-threatening diseases. This simply shows how important it is for you to remove them from your home and make sure they don't find their way back.
Disease transmission from rats to humans can occur through several routes. These include;- Human exposure to wastes of rats such as feces, saliva, nesting materials, and urine while handling or removing them from homes.
- Bites from rats that are infected.
- Unsafe handling of rats (touching of rats without wearing gloves) and eating food that is contaminated with rat feces, urine, or saliva.
Diseases can be transmitted from rats through any of the above means. This clearly shows that if you have rats running around your home, you are at a high risk of getting infected. The following are some of the possible diseases rats can carry.
1. Hantavirus
This particular disease is one of the most life-threatening diseases that rats carry. Currently, Hantavirus is yet to have a known cure, vaccine, or treatment. Some of the symptoms of this particular disease include abdominal pain, vomiting, diarrhea, and nausea.
2. Salmonella
This particular disease is a bacterial infection carried in the digestive tracts of rats. When they pass feces, it usually contains a large proportion of this bacteria. If by mistake you consume any food substances that are contaminated with this bacteria, you might contract Salmonella. Some of the symptoms of this disease include diarrhea, vomiting, fever, chills, nausea, and abdominal cramps.
3. Lymphocytic Choriomeningitis Virus
This disease is another life-threatening disease that rats transmit to humans when there is contact. LCMV is capable of causing encephalitis and meningitis if not quickly managed at its early phase.
4. Rat-bite Fever
Unlike other types of diseases, rat-bite fever is only transmitted when a rat bites you. The bacteria of this disease is found in the saliva of rats. The symptoms of this infection include high fever, muscle pain, headaches, and skin rash.
