Fountain Valley has a raccoon problem shaped by one thing above all others: Mile Square Park sits in the middle of it. Six hundred and forty acres of irrigated turf, two lakes and a nature area, surrounded on all four sides by single-story houses with tile roofs. Raccoons need water and they need a dry place to raise young, and in this city those two things are about a five minute walk apart.
Fountain Valley specifically
Most of Fountain Valley was built between the mid 1960s and the late 1970s, and the housing is remarkably consistent: single story, slab on grade, tile or shake roof, attached garage. That consistency matters, because it means the raccoon entry points are consistent too. With no crawlspace to get under, an animal that wants shelter here goes up, and a single-story roofline is an easy climb from a fence, a patio cover or a mature tree.
The land itself is the other half of the story. This is flat, low-lying ground with a high water table, farmed as wetland well within living memory, and the Santa Ana River channel runs the full eastern boundary. Between the river corridor, the Mile Square lakes and fifty years of mature irrigated landscaping, water is never a limiting factor for wildlife in Fountain Valley. That supports raccoon densities you would not expect from a city this suburban.
Where they actually are
On a Fountain Valley house the answer is nearly always the attic, and the way in is nearly always the roof rather than the walls. Raccoons are strong and genuinely dexterous, and a plastic attic vent or a thin gable louver is not an obstacle to one.
We check roof and gable vents first, then the ridge and the eave line where barrel tile leaves a gap wide enough to work under, then the junction where a patio cover or room addition was tied into the original roof. That last one is the single most productive spot in this city, because so many Fountain Valley homes have an added-on patio enclosure and the flashing where old roof meets new is rarely sealed to a standard that stops a determined animal. Chimneys without a proper cap and open sheds round out the list.
The signs people miss
- Heavy, deliberate footfalls overhead at night, distinctly slower and louder than rodents. People describe it as someone walking in the attic, and that description is usually accurate.
- Chittering, chirping or crying sounds in spring. That is a litter, and it changes the job completely, because removing the female without the young creates a much worse problem.
- A torn or pushed-aside roof vent, lifted tile along the eave, or a gable louver bent outward. Damage that looks like it was done with hands rather than teeth is the tell.
- A latrine: a concentrated pile of droppings used repeatedly in one spot, often on a flat roof section, a patio cover or in one corner of the attic. Do not disturb one, and do not sweep it dry.
How we handle it
The free inspection is a roof and attic inspection. We establish whether the attic is currently occupied, whether there is a litter, and every point on the structure an animal is using or could use. Getting that wrong in spring is how people end up with young sealed in a ceiling void, which is both a serious odor problem and an avoidable outcome.
The work is cage trapping and exclusion. Once the structure is confirmed clear we close it with materials that hold up to an animal that can pull, which in practice means heavy galvanized steel vent covers rather than the plastic that failed, sealing the tile line at the eave, and properly closing the patio-cover junction. A chimney gets a cap. We would rather do this once with the right materials than come back.
On latrines and roundworm
This is the part of a raccoon job that people underestimate, and it is worth being direct about it. Raccoons establish latrines, and raccoon droppings can carry Baylisascaris procyonis, a roundworm whose eggs are hazardous to humans and pets and remain viable in the environment for a long time.
The practical advice is simple. Do not sweep or vacuum a dry latrine, because that puts material into the air. Do not let children or pets into an area where you have found one. Contaminated insulation is not something to salvage. We remove, bag and haul the affected material and clean the area rather than leaving it in place, and we will tell you plainly if what we find in your attic warrants a full cleanout rather than a spot clean.

How we handle the animal
Cage trapping and exclusion, not chemicals. We do not apply pesticides, rodenticides or bait on any job, and we do not use body-gripping traps in residential settings.
Every trap we set is checked at least once every 24 hours. Where 14 CCR § 465.5(g)(2) applies it requires trapped animals to be handled in accordance with state regulation rather than moved somewhere else, and we will explain exactly what that means for your property before anything goes in. If a company tells you they will release your raccoon in the hills, they are either not being straight with you or not operating within the regulations.
From roughly February through May, assume any raccoon in an attic is a female with a litter until proven otherwise. Sequencing that job correctly is the entire difference between a clean resolution and tearing open a ceiling in July.
Raccoon pressure in Fountain Valley, park to river
Draw a ring around Mile Square Park and you have drawn most of our Fountain Valley raccoon map. The streets immediately bordering the park on Euclid, Warner, Brookhurst and Edinger produce steady work, and the two lakes inside it are why. Water plus cover plus an unbroken supply of single-story roofs on the other side of the fence is close to ideal.
The Santa Ana River corridor along the eastern edge is the second driver, feeding the neighbourhoods off Talbert and Ellis. The Los Caballeros and Green Valley areas generate a consistent stream of calls, and the added-on patio enclosures common in those tracts are usually the entry point. Where we see fewer structural jobs is the newer condo and townhome product, though those areas produce more trash-enclosure and courtyard complaints, which is a different problem with a different fix.
Questions we actually get asked
We hear something heavy walking in the attic at night. How do we know it is a raccoon and not possums or rats?
Weight and cadence. A raccoon sounds like a person crawling around up there, with slow deliberate thumps and often a dragging noise. Opossums are lighter and slower still, and rats are fast, light and scratchy rather than heavy. The other reliable tell is the entry point: raccoons tear and pull, so a bent vent, lifted tile or a hole with the edges pushed outward points to a raccoon. Rats leave a neat opening the size of a golf ball.
It is April and we think there are babies. Should you just trap the mother and take her away?
No, and this is the most important thing to get right on a spring job. Removing the female and leaving the litter behind means the young die in your attic or a ceiling void, which turns a straightforward removal into an odor and contamination problem that requires opening the structure. The correct approach is to confirm whether there is a litter and where it is, then sequence the work so the family leaves together. It takes a little longer and it is enormously better than the alternative.
Our patio cover roof joins the house and we think that is where they get in. Is that common here?
It is probably the single most common entry point in Fountain Valley. So many homes here have an added patio enclosure or a converted porch, and the flashing where the new roof was tied into the original is frequently just sealed with caulk or a bead of mastic. That degrades in ten years and leaves a gap right at the eave, which is exactly where a raccoon on a fence would look. It is very fixable, but it needs proper metal work rather than more sealant.
The rest of what we do in Fountain Valley
A hole big enough for a raccoon has usually been found by something else too. When we are on a roof we check the whole structure, and these are the Fountain Valley services most often paired with this work.
Licensed for the work we advertise, and clear about the rest
Wildlife control, structural pest control and construction are three separate licenses in California. Plenty of companies blur that line. We would rather tell you exactly where ours sits.
- Wildlife trapping and exclusion — this is us. Tri County Trappers operates under California Department of Fish and Wildlife Trapping License TP-10188, and every technician on our crew carries their own CDFW trapping license. Not a company license with unlicensed helpers under it. Each one, individually licensed by the State.
- Attic cleanout and decontamination — this is us. Removal, bagging, vacuuming and cleaning of contaminated material. We do not apply pesticides, rodenticides or bait on any job.
- Insulation, wood repair and structural work — not us. Tri County Trappers does not hold a Contractors State License Board license. That work is performed by a licensed contractor. We inspect it, document it and hand over the photographs so nobody starts cold.
- Structural pest control (Branch 2) — not us. If your situation needs it, we say so and point you to a licensed structural pest control operator rather than stretching our own license over it.
General liability, professional liability, workers’ compensation and commercial auto, all current, with limits well above what the State requires of a licensed trapper. Certificates on request, before you let anyone on your roof.
