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
Are rats hibernating creatures?
Rats are nocturnal:
Rats sleep a lot even without cold conditions. The average rat will sleep between 12 to 15 hours a day and in colder conditions they will often seek warmth so that they can sleep safely for this amount of time. Because rats often walk around at night, detecting them can be somewhat difficult. Making sure that you can detect them often means checking into areas where they could nest or remaining somewhat attuned to what is going on in the night time when they are most active.
Rats breed throughout the year:
Even in the wintertime rats are continuing to breed, make their nests, and live without any issues. They don't hibernate during winter. Instead, rats will continue to breed. Most rats are able to wean a litter in about one month and leave the babies to fend for themselves after that period of time.
Rats will seek spaces to live:
Even though they don't hibernate, rats will seek warm and safe conditions. This means that in the wintertime it's likely that they will be looking for space inside your home where they can spend time sheltering throughout the winter. Spotting areas were rats can get into your home can be important to preventing an infestation.
Food gets scarce in winter:
If you are in an area where the climate gets cold this can lead many rats to find an area where they can access food much easier. Rather than getting stuck with very little food supply over several months, they can detect food that's in your home and then stay close to it.
