Twin Home Experts has served over 30,000 customers in Los Angeles with their plumbing, leak detection, HVAC, mold and water damage needs. We are a top leak detection expert in Los Angeles, and use the best leak detection equipment in the industry.

One of the hardest service calls we get is “I hear noises in my attic & walls at night and need to find out where the mice entry points are in my house.”

Our team at Twin Home Experts is equipped with micro cameras, proper inspection protocols and UV smoke injection equipment – which is our personal favorite.

We often get calls directly from pest control companies to help track down where rodents are entering in with respect to the pipes in a home after they exhausted themselves searching everywhere else.

Mice often live in hidden areas within homes, including storage boxes, attics, lofts and wall interiors. They are capable of fitting through extremely small openings in floors, walls, foundations and pipes that are broken.

After they enter homes, they can be extremely difficult to get rid of.

Why it’s difficult to get rid of mice

Mice living within walls rarely leave their nests during daylight. Their presence is made obvious by gnawing and clawing sounds. Before attempting extermination methods, Los Angeles homeowners should properly identify their pests as mice. Other pests are also known to reside within walls and may require a customized method to control them.

Droppings and tracks are often visible in homes experiencing mouse infestations. Holes are also visible in walls, floors, ceilings and foundations. Due to their nesting and feeding habits, mice cause significant damage to human food sources and wooden surfaces. Bite or chew marks in these areas often indicate the presence of mice, check out our video where the mice were chewing through the drywall.

Rodents living within walls do emerge in search of food. At this time, homeowners may capture or kill mice through the use of traps. Homeowners may also lure mice out of walls with food bait. Spring-loaded traps, glue traps and live-catch traps are commercially available. Some are designed to kill captured rodents, while others require homeowners to release mice outside.

In order to be effective, the traps must be placed properly and along areas frequented by the mice. Often, homeowners incorrectly place traps, making them ineffective, and they can also present a risk to children or pets if they have access to the trap.

Professional pest control should be sought for the knowledge, training and expertise to successfully manage mice, like the company that called us out, Rodent Stop. They do a fantastic job tracking down the mice entry points.

Case study: Finding the mice entry point

A Los Angeles rodent company uses Twin Home Experts to pinpoint where the entry points where mice are coming into the home. The customer can hear the mice scraping away at the inside walls as shown in this photo:

These marks make it very clear that this is where all the action and noise is happening, this is what’s keeping our customer awake at night.

So now that we’ve opened up stucco and verified the proof, we have to be on the hunt and perform detection work to pinpoint where these rodents are coming in.

So, we found a sewer vent pipe right next to the drywall scrapings inside the wall.

Our team went up on the roof and identified the pipe, setting up shop to inject smoke into this vent pipe to see if we can locate the breach or broken sewer pipe inside this wall.

We injected about 8 minutes of smoke into this drain vent stack and sure enough, inside the attic we found the broken pipe with smoke just pouring out.

This is where the mice entry point is into the inside walls of a home.

Our customer jumped up with joy that we found it! She stated that she has had so many professionals come out unable to find the mice entry points.

Here is the video footage of the broken pipe Twin Home Experts found and solved the problem.

What you can do

  • Fix any leaky outdoor faucets so you’re not providing pests with a water source.
  • Inspect your home for any holes that pests could use as entry points. If you see any, have a professional properly seal them. Or better yet, have a professional do the inspection for you.
  • Try to keep your gutters and yard free of all debris, including acorns, fallen fruit, gardens that have gone to seed, pinecones and so forth.
  • Keep vining plants, shrubs and tree branches trimmed so that they don’t provide access to your home.
  • Don’t leave pet food or water outside at night.
  • Tightly tie trash bags and keep the lids to your trash cans secured.
  • Keep a tidy home, especially in the kitchen. Don’t leave food out, and be sure to clean up spills and crumbs. Remember to sweep by your fridge, stove and trash can, wipe under toaster ovens and around rice cookers, and empty tray crumbs in toasters.
  • Store food (including pet food) in containers made of metal or glass so that you’re not providing pests with an all-they-can-eat buffet.
  • Stack firewood or leaf piles far away from your home.
  • Make sure all drain pipes are secure and not broken like vents in an attic or wall.
