Fountain Valley has no canyons and no hillsides, which is exactly why people here are caught off guard by coyotes. They arrive along the Santa Ana River channel, which runs the entire eastern boundary of the city and connects the mountains to the coast without a single break, and they hold in Mile Square Park, six hundred and forty acres of irrigated open space sitting in the middle of a fully developed suburb.
Fountain Valley specifically
The river channel is the route and Mile Square is the destination. That park has water in two lakes, cover in the nature area, and an enormous prey base of ground squirrels, gophers and rabbits living on irrigated turf. It supports coyotes comfortably, and the neighbourhoods on all four sides of it are the ones that see them.
What makes this city different from a canyon-edge community is that the coyotes are living inside the urban footprint rather than outside it. There is no wildland boundary to point at. That changes the advice slightly: attractant management across a neighbourhood matters more here than perimeter fencing at the city edge, because the animals are already in the middle and the food that holds them is in people’s yards and shared trash areas rather than in the wild.
What we actually offer
Five things, and we would rather be clear about which do the heavy lifting.
Hazing comes first because it works and it is what the California Department of Fish and Wildlife recommends. Consistent, coordinated hazing re-establishes a coyote’s wariness of people. Fencing and exclusion is the physical deliverable: height and extensions, coyote rollers, dig barriers at the base, and the gate and grade details where animals actually cross. Maintenance is the ongoing program, which is the realistic answer for any property on the park perimeter or the river corridor.
Trapping is a last resort for genuine public safety situations rather than a first response. Where it is warranted we use cage traps, monitored daily. Pheromone applications are the scent-based side of the work. Applied at the points where animals are actually entering and travelling, they signal that the territory is already held and encourage coyotes to route around a property rather than through it. This works best alongside hazing and exclusion rather than on its own, and we will tell you honestly where it is likely to help and where it is not.
The attractants people miss
- Pet food and water left outdoors, including bowls on a patio and in an open garage. The most common single attractant we find and the easiest to remove.
- Fallen fruit from the mature citrus and avocado planted with these tracts fifty years ago, which is a nightly food source nobody thinks of as feeding wildlife.
- Unsecured trash around collection days, and shared enclosures in the condo and apartment areas.
- Rodents. Fountain Valley has significant gopher and roof rat pressure, and a property with an active population is feeding coyotes whether anyone intended it or not. On the Mile Square perimeter this is the single biggest driver we see.
- Cats left out overnight, and small dogs let into an unlit yard alone after dark. Both are why this becomes an emotional issue on a street very quickly.
How hazing actually works
Hazing means responding to a coyote’s presence in a way that is consistently unpleasant and consistently human. Being large and loud, staying visible, and never turning away first. What matters is that it happens every time from every person, so the animal learns people are reliably a bad experience rather than occasionally one.
The failure mode is inconsistency, and in a city like Fountain Valley that is the whole battle. Because the coyotes live in the middle of the neighbourhood rather than beyond a fence line, they interact with dozens of households a night. One family hazing while the rest ignore it teaches the animal nothing except which yard to avoid. This works when a street or a tract does it together, which is why we run it as a program with training and material rather than as a single visit. The Laguna Woods community hazing program linked below is the closest comparable.
Hazing is also not right for every situation. It is not the answer for a denning site with pups, and it is not the answer for an animal showing genuine loss of fear or aggression. We will tell you which situation you are in.
Fencing, and what actually stops a coyote
Most fences do not. A coyote clears five feet without much effort, climbs wood and chain link, and where it cannot go over it goes under, since they dig readily at the base. A great deal of Fountain Valley fencing is original block wall or older wood at a height that stops nothing.
What works addresses both directions at once. Six feet or more of height with a roller bar or outward-angled extension along the top so there is nothing to grip. At the base, a buried barrier or an apron extending outward to defeat digging, which matters here because the soft, high-water-table soil this city sits on digs very easily. Then the details, which is where most installations fail: the gap under a gate, the low point where a wall steps down, and the woodpile, planter or A/C unit sitting against the wall as a launch point.
On the Mile Square perimeter, fencing is usually the highest-value work available, because it is the only thing that holds when nobody is home and the park is not going anywhere.

On trapping, and what California actually permits
We lead with non-lethal work. Trapping is a last resort for genuine public safety situations.
Where trapping is warranted, Tri County Trappers operates under California Department of Fish and Wildlife Trapping License TP-10188, and every technician on our crew carries their own. 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.
We will be direct about this because the industry generally is not. California does not permit relocating a trapped coyote to the river bed, a regional park or the hills. Any company telling you otherwise is either misinforming you or not operating within the regulations. Coyotes are also territorial, so removing one animal typically opens the territory to another within weeks. In a city where the habitat sits in the middle of the neighbourhood, trapping alone reliably buys time rather than resolving the situation.
Coyote pressure across Fountain Valley
The ring of streets around Mile Square Park carries the great majority of this work. Properties along the Euclid, Warner, Brookhurst and Edinger edges of the park sit against permanent habitat with water, cover and abundant prey, and the fence between is not much of an obstacle. Those addresses do best on a maintenance rhythm with fencing addressed properly.
The Santa Ana River corridor along the eastern boundary is the second route, feeding the neighbourhoods off Talbert and Ellis, and it connects Fountain Valley to Costa Mesa’s Fairview Park and Talbert preserve to the south. Interior tracts through Green Valley and Los Caballeros see less, and when they do it is usually a single animal following a specific food source rather than established activity. Those situations often resolve quickly once the attractant is identified, which is why the first thing we do on an interior call is work out what is drawing it in.
Questions we actually get asked
We are nowhere near a canyon. Where are these coyotes even coming from?
The Santa Ana River channel and Mile Square Park. The channel runs the full eastern edge of the city and is an unbroken corridor from the mountains to the ocean, so animals travel it without ever crossing a major road. Mile Square then provides everything a coyote needs to stay: water in the lakes, cover in the nature area, and a large population of gophers, ground squirrels and rabbits on irrigated turf. They are not visiting from somewhere rural. For practical purposes they live here.
We back onto Mile Square. Can this be fixed or is it permanent?
The park population is permanent and we will not pretend otherwise. What is fixable is your property. That means the wall or fence addressed for both climbing and digging, which on this soil matters more than people expect, attractants removed, pets managed after dark, and consistent hazing so animals crossing the area stay wary. Properties on that perimeter generally do best with a maintenance interval rather than a one-off visit. Anyone promising a permanent single-visit fix on that street is selling you something.
Our neighbour feeds them. What can we actually do about that?
It is the most frustrating version of this problem and unfortunately it is common. Deliberate feeding is what turns a wary animal into a bold one, and it undermines everything the rest of the street is doing. Practically: harden your own property first, since that is entirely within your control, and remove your own unintentional attractants. Then it becomes a neighbourhood conversation, and it usually goes better when it comes with information rather than accusation. We are happy to provide material explaining why feeding creates the risk, which tends to land better coming from a licensed operator than from a neighbour. Where there is an HOA, the association can generally address it directly.
The rest of what we do in Fountain Valley
Coyotes usually turn up alongside whatever is feeding them, and in Fountain Valley that is very often the gopher or rat population in the same yard. These are the services most often paired with coyote work here.
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.
