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 The Different Sounds Rats Make When They Are In Your Home?
Chittering:
The sound of chittering is often the sound of a rat chomping or grinding their teeth against building materials in your home. This type of behavior is fairly common for rats to sharpen their teeth as well as for nest construction. If you find that a rat in your home is making a chittering noise, this could be an indication that they are building a nest and ready to have children.
Hissing:
Hissing noise is often the sound of a rat in danger or a rat that is angry. Rats can be extremely territorial and if they are in an area of another rat that has a nest or they encounter a family pet there's a chance that they could hiss. If you approach a rat and hear a hissing sound, a rat could be simply trying to assert its dominance over you.
Squeaking:
Squeaking is often a communication method that is used between rats. The process of squeaking is fairly common in mice as well as in rats. The squeaking sound can be an indication that a rat is content and it is also a fairly common way to identify rats that could be in the walls or in close areas to your location. It's often difficult to hear a squeaking sound but if you have several rats in your home it can be easier to pick up as they start to move through the walls.
Rustling:
Rustling sounds are often the process of nest construction and these can happen outside the home or inside the home as a rat drags materials to build a nest. If you notice the sound of rustling, it is crucial that you consider contacting a pest professional as you could be facing rats that are reproducing.
