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
Reasons Why Rats Die Inside Attics And Houses
They Get Thirsty:
Rats often get thirsty when they have ingested any type of poison or when they cannot find their way out of a house. When rats go in search of water, they go towards an area where they will be closest to the outside world. When they have difficulty getting out of the home, they may find themselves in the attic close by their water source that they desperately need but unable to access a way out of the home.
They Get Poisoned On The Way Back To The Nest:
Rats will often travel throughout the home after they've been poisoned. Because poison often takes a bit of time to take effect, a rat might make its way up to the attic to stay warm and then die on its way back from the attic.
They Bleed Out:
Rats that have been affected by spring traps and other means for capturing may bleed out if they sustained serious injuries. This can happen quite quickly especially if the rat has made its way up to the attic to try and escape. This often becomes the final resting space for rats and this can eventually lead to foul odors.
They Get Stuck In Glue Traps:
Glue traps can be another cause for a rat to get stuck in an attic area. When a rat gets stuck in a glue trap it's possible that it will simply die in the area which can lead to people finding the rat or the rat causing a series of issues with smells and rotting. Glue traps are commonly placed in attics because this can be an easy place as it is out of sight for pets, toddlers, and home/business owners.
