Scratching in the ceiling at night, droppings in the garage, something moving in the walls. If you have rats or mice in Signal Hill, we get them out and seal the building so the next ones cannot get in. Licensed, insured, owner-operated, and rated 4.9 stars on Google.
Why Signal Hill has a rodent problem
Signal Hill packs a lot into a small footprint: older homes, steep grades, active and legacy oil infrastructure, and undeveloped hillside lots sitting directly against residential streets. Those open lots hold rodent populations that no amount of work inside a single house will change.
Because the city is small and elevated, properties tend to share pressure from the same few open areas. Rats work their way down from the hill into the streets below, and the homes on the uphill edge take it first. If you back onto open ground here, exclusion is not optional maintenance, it is the whole job.
Roof rats and Norway rats are not the same problem
Which one you have determines where we look and what we seal, so it is the first thing we establish.
- Roof rats are the common one across Los Angeles and Orange County. Slim, dark, with a tail longer than the body. They are excellent climbers and live high, in attics, wall voids, palms and dense landscaping. If you hear scratching or running overhead at night, it is almost certainly roof rats.
- Norway rats are heavier and blunt-nosed with a shorter tail. They burrow, and they stay low, in crawl spaces, under slabs, along foundations, near sewer and drain lines. Their damage shows up at ground level.
- House mice get in through much smaller openings and reproduce faster, so a small mouse problem becomes a large one quickly. A mouse only needs a gap the width of a pencil.
How we handle rodent control calls in Signal Hill
Photos are from our own crews on real jobs across Orange County and Los Angeles — never stock. We run these same steps on every Signal Hill call.
Signs worth taking seriously
- Scratching, scurrying or thumping overhead, usually starting shortly after dark
- Droppings in the garage, pantry, attic or along wall bases
- Gnaw marks on wiring, plastic pipe, or stored boxes
- A persistent musky odor that gets stronger in warm weather
- Insulation that looks flattened, tracked through, or pushed into piles
- Dogs or cats fixating on one spot on a wall or ceiling
Chewed wiring is the one we treat as urgent. Rodent damage to electrical is a documented fire risk, and it is also the kind of loss insurers ask hard questions about.
Why we lead with exclusion instead of bait
Most companies will set bait stations and put you on a monthly schedule. That model is good for recurring billing and bad at actually ending the problem, because it never addresses how the rodents are getting in. Kill the ones inside and leave the gaps open, and the property simply refills.
We work the other way around. We inspect the structure to find every viable entry point, and there are usually more than people expect, since a roof rat gets through an opening the size of a quarter and a mouse through far less. We seal those openings with materials rodents cannot chew through, rather than foam or mesh that buys a season. We remove the animals already inside by trapping. Where droppings and nesting have contaminated insulation, we handle the cleanup, because rodent waste in an attic is a genuine air-quality issue and not just an unpleasant one.
Then we tell you the truth about your property. If a neighbor’s untreated yard, a channel, an open lot or a commercial building nearby is the actual source, you deserve to know that rather than pay us indefinitely to manage a symptom.

What to do before we get there
Nothing dramatic, but a few things genuinely help. Stop putting bait out, because a rodent that dies inside a wall is a problem we then have to find. Pick up fallen fruit and pet food left outside overnight. Trim branches that touch the roofline, since that is a bridge. And note where and when you hear activity, because the timing and location tell us a lot before we ever open the attic.
What rodent control costs in Signal Hill
Rodent work is priced in two parts, because it is genuinely two jobs.
- Sealing the building, $500 to $800 for a standard sized home. Priced by how many repairs it takes to make the property inaccessible, not by how many holes are visible from the driveway.
- Cleaning up what they left, $1,500 to $6,000. Contaminated insulation out, the space sanitised, and new insulation in where it is needed. Square footage is the biggest driver.
Plenty of homes need the first without the second. We will tell you which one yours is, and we will tell you if it only needs sealing. See what all of our work costs, including trapping and gopher removal.
The inspection is free with no conditions, and there is no trip fee if you decide not to go ahead. We can usually be out the same day.

OUR METHOD
No rodenticides. No baits, powders, or treated devices.
We work with live traps and exclusion only — on every job, every time. That eliminates the secondary-poisoning pathway that kills owls, hawks, and the pets that eat poisoned rodents. California Department of Fish and Wildlife Trapping License TP-10188.
