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
How Deep Do Rats Dig Holes Or Burrow Under Houses?
Asides from being a very smart animal with a high sense of adaptability, rats are keen diggers. With their dexterous paws and strong teeth, they can chew through plastic, wood, and even aluminum. This clearly shows how much of a good digger these rodents are. Also, if you have holes around your house, these rodents might be responsible for creating them.
Maybe you have rats digging holes or burrows under your house and you have always wanted to know how deep these holes are. The fact is these excellent diggers can dig holes as long as 3 feet and as deep as 18 inches. This digging skill allows them to create deep burrows and holes under your home
Due to their smart nature, rats don't just dig burrows and holes blindly. They dig with plans and prepare for the worst-case scenario by creating one or two exit points apart from the entry hole, in case they are attacked by a predator. Therefore, if you see a rat hole or burrow around your house, you must look around to find its exit hole. Unlike the entry hole which is usually clean and free from dirt, rats usually use thatches of grass to conceal their exit holes. This simply means you have to look around carefully to find it.
While examining these holes and burrows, you need to be very careful and avoid moving too close to it. Snakes or any other harmful animal could also be inhibiting the hole. If you have to dig in the hole or make close contact, make sure you are well protected.
