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
Where Do Rats Live During The Summer?
Rodents have been able to colonize most of the earth's habitats. Different species of mice and rats are found from warm deserts to tropical mountains. Polar zones are considered the only place without rodents.
During summer, their survival instinct takes rats to shelter in place in which food is abundant and easy to get. The favorite places for rats are country houses and barns that provide them plenty of food. On the other hand, in the cities, most of the rats live in sewers where they feed on fruit, meat, and bread residues that are discarded in the garbage.
The Urban Plague
Rodents are big and repulsive. The two most known species are the gray rat or sewer rat, (Rattus Norvegicus), and the black rat or roof rat (Rattus Rattus). Although there are different species, they are both characterized by their lack of hygiene, as they live in filthy areas.
These creatures have the ability to acclimatize in urban environments because with the arrival of summer, they reproduce and start to invade people's homes to find food and shelter. Rats are among the animals that proliferate the most during summer since proper conditions for the pups' development are warm and dry conditions.
Inside Homes
Rodents will look for food and residues left on the floor. Also, places with plenty of holes and clutter. From a small crack in the wall to a space behind the fridge or the washing machine, these will be perfect places for a rodent to find refuge to save its food, live comfortably, and reproduce.
To prevent invasion problems, it is advisable to call a specialist in pest control. Proper rat extermination should be combined with actions such as tightly closing garbage cans, cleaning of the house, and other preventive measures.
