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
Can Rats Make Chirping Noises?
Rats are nocturnal animals; they avoid brightly lit places at all costs and prefer damp, dark places out of sight. But because of their great agility and incredible dexterity, they can fit into any place and their presence will be almost imperceptible, due to the low sound frequency they emit.
Rats Communicate
Although they obviously cannot talk, rats have the ability to communicate through pheromones, which are chemical substances secreted by living beings; they use these to warn other rats about any danger. Also, they use vocalizations (almost imperceptible sounds), to associate with pain, discomfort, or uneasiness.
They have other sounds in a higher ultrasonic frequency to identify well-being. It is said that there are specific interactions using a shriek; sexual activities, communication between mother and pup, or situations where the aggressiveness of other rats can be identified.
So Are Rats' Sounds Really Imperceptible?
Their sound is almost imperceptible to the human ear, but among them, this form of communication is very powerful. Their senses of smell, touch, and hearing are highly developed and this is what allows them to walk so boldly through the night.
But if we pay attention and are close enough, we can perhaps hear their gnawing, prowling, and even fighting movements. Just keep in mind that if you are close enough to perceive their screeching, it is because the rat feels in danger and these animals, unlike mice, can attack!
Can This Squeak Affect The Human Ear?
These sounds could not affect in any way your ear; but it may affect our well-being, as their sound can attract more and more rats over time, and this can become a real headache.
Surely you don't want to have a family of rats hanging around your house, your kitchen, or your restaurant. The best thing to do is get rid of rats as soon as you realize they are present in your property.
