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
Rats And Black Pepper
Rats eat almost anything. In their search for food, they can gnaw on plastic, wood, and even electrical wiring. A rat presence in your home can cause a lot of economic damage.
When this expense is added to the health problems rats' body fluids can cause, the best thing a person can do is getting them out of the house as soon as possible. The most common extermination way is using traps or rodenticides. However, there are more natural methods such as the use of peppers that cause unpleasant odors and tastes for the rodent and quickly drive them away.
Odors That Repel
Using repellents with unpleasant odors for rats is a way to keep them away from you in a friendly way. The advantage of not having to deal with the rodent's carcass can be worth the effort of constantly using these temporary methods. Rodents use their sense of smell to socialize as well as to survive. An odor such as ammonia often drives them away because it is very similar to the urine of large animals that could devour them. Spicy odors are perceived as dangerous chemicals that are also often avoided at all costs.
Black Pepper
Spicy food odors are unbearable for rats, thanks to their high capsaicin content. These natural compounds give the food its spicy effect, but they are also often very irritating to the mucous membranes and lungs of rodents. If ingested, they can cause a burning sensation in the taste buds and olfactory glands. Pepper is known to be able to scare away rats temporarily although this is not scientifically proven.
For all those people who are afraid of having to deal with poisons or homemade traps, finding new and less harmful options is a headache; however, homemade repellents like black pepper avoid harming other animals and humans, being a perfect choice. In any case, even if they are harmless odors, it is advisable to seek the advice and follow the instructions of a professional in the field.
