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 Is The Natural Diet Of The Black Rat And Norway Rat?
Black Rat
The black rat (in many cases called the ship rat) has a smooth and incredibly long tail that is longer than its head and body. Romans were the ones who brought this species to Britain. The color of the black rat fluctuates from dark to grey-brown. When compared with brown rats, these creatures have little bodies and bigger ears and eyes. Black rats are amazing climbers. They are fit for running along phone wires, utilizing their tails to adjust while moving. The species is additionally called 'rooftop rat' due to building their homes high in rooftop spaces.
Diet
Black rats are viewed as omnivores and eat a wide scope of foods, including seeds, natural products, stems, leaves, fungi, and an assortment of invertebrates and vertebrates. They are generalists, and as a result, not picky on their food choice, which is demonstrated by their propensity to benefit from any meal given to cows, pigs, chickens, felines, and dogs.
Norway Rat
The main thing to know is that, regardless of the name, the Norway rat isn't really from Norway. It is believed that the name originated from a man named John Berkenhout, a British naturalist, who concluded that the brown rats had migrated to the UK from Norway. Present-day researchers think that this type of rat actually originates from China. They showed up in the British Isles most likely transported via ships and goods.
When they got to the UK, be that as it may, they immediately multiplied and set up for business there. That is the reason they are otherwise called the common rat, the road rat, the sewer rat, or the brown-colored rat.
Diet
Norway rats will eat pretty much anything. If they get inside, they'll search in your kitchen cupboards and pantries. Specifically, the rats are looking for meat and even fish; however, they will also feast cheerfully on dry dog food. When they discover the food, they will eat and eat, glutting themselves on what they find, and if they smell food, they'll chew through plastic, lead pipes, wood, and anything else to get there.
