Denline Wildlife Control · Fallowcross & the Coldmoor woods · Since 2006
The animals were here first. We just draw the line at the attic.
Denline evicts and excludes — a one-way door over the entry, galvanized mesh in every gap a pencil could pass, chimney caps and vent guards to keep the next family out, and the insulation restored once the tenants have gone. No poison, no glue, no dumping an animal into somebody else’s woods — it leaves on its own schedule and cannot get back in. That is the entire craft.
Services
The species index
01
Gray & red squirrels — 7 to 10 days out
The dawn racket in the soffit, the cache of cones in the flue. A one-way door over the entry and the loft goes quiet inside a week; then the mesh goes in, the flue capped, and the branch that made your roof a footpath trimmed back with the owner’s blessing. Attic insulation tamped by squirrels is restored, not just deodorized.
02
Raccoons — 10 to 14 days, never in spring kits
A mother raccoon reads a chimney as a den tree with better weather. The eviction door goes up, the kits — if any — are gathered by hand and placed in a warming box she can reach, and she moves the family to the second-best den she already knows. Chimney capped, soffit closed, and the lawn grubs that drew her get the honest mention.
03
Bats — August to April only, by law and by sense
A colony is evicted by exclusion matting over the entries — but never between late spring and mid-summer, when flightless pups inside would starve behind the one-way flap. The season is the ethics and the legislation in one; guano removal and a proper attic restoration follow, and the return clause is written for the next August, not the next invoice.
04
Skunks, mink & the under-deck nations
The smell arrives before the animal does. One-way doors at the deck line, the dig-proof skirt buried and lapped outward, and whatever was living under the hot tub leaves for the hedge line it came from. Odour neutralization is a chemistry we do honestly, and the fence line survey keeps the next spring from repeating.
Evict · Exclude · Restore
The three quarters of the craft
Evict — the one-way door
A door over the entry the animal can push out and cannot push in. No trap, no transport, no dumped animal starving in unfamiliar woods — it leaves for the den it keeps as a spare, on its own legs, usually the first night.
Exclude — mesh, caps & skirts
Galvanized hardware cloth in every gap, chimney caps that still draw, vent screens, and dig skirts lapped outward at the deck line. The audit is a pencil: anywhere it passes, so does a mouse, and everything it passes gets metal.
Restore — the attic, reset
Droppings and nesting out, contaminated insulation vacuumed with the right filtration, odour sources neutralized, fresh insulation blown to spec. The space above your ceiling ends the job as a place animals have no opinion about.
How it goes
From noise to silence
The same sequence on every job — the only variable is your project.
Day 0
The roof-line audit
Ladder and torch around every elevation, the pencil test at every joint, the flue scoped, the attic walked in suits and lights. You get the map — every entry, every would-be entry, and which animal is using which, because the treatment follows the species.
Day 1
The door goes up
Entries closed except one, the one-way door fitted and lapped so it cannot be torn off, kits gathered and placed where a mother can collect them. The house goes quiet on the animal’s schedule — days, not hours, and we say which days for which species.
The watch
Ten quiet nights
The door watched — cameras where a watch matters, chalk and thread where it does not — until nothing has pushed out for a run of nights. Only then does the last entry get metal, never before.
The close
Metal in every gap
Mesh, caps, screens and skirts fitted to the map; every closure photographed and listed on the letter you keep. This is the part that outlives everything else on the invoice.
After
The attic, reset
Guano and nesting removed under containment, insulation replaced to spec, the hatch sealed and labelled. And a year later the entry audit is re-walked free, because exclusion is a claim we would rather prove than state.

Recent evictions
Six jobs from last season, photographed at the close-out walk — every gap on the map holding metal.
Denline, in figures
Squirrels in the soffit three springs running; two “trappers” who took animals away and solved nothing. Denline put the door up, waited for ten silent nights, and then sealed every gap on a map they drew and left with us. This is the second spring of nothing at dawn, and the branch they asked us to trim was the whole story.
A raccoon and her kits in our chimney in April, and the thing I remember is the warming box — placed where she could reach it — and the tech explaining she would move them to her spare den that night. She did. The cap went on the following week and the invoice matched the letter to the cent.
The school’s bat colony was the kind of job nobody wants in the paperwork. Denline timed the exclusion to September, removed the guano under containment, reset the attic insulation, and produced a letter with photographs of every closure that satisfied the governors, the insurers and the heritage officer — the first document in the file that made all three nod at once.
Fair questions
Questions from the kitchen table
The five every wildlife call starts with. The law and the seasons are part of the answers, which is why they are written down instead of improvised.
Why not just trap them and take them to the woods?
Because a relocated territorial animal mostly dies — of stress, starvation or a fight with whoever already owns the woods — and because an entry left open is a vacancy sign for the next animal within the season. The one-way door solves both: the animal walks to a den it already knows, and the house is closed behind it. Trapping answers an invoice; exclusion answers the problem.
How do you know they are all out?
The species sets the watch. Squirrels clear in seven to ten days, raccoons ten to fourteen, and the door is watched — cameras or chalk and thread — until a run of quiet nights, not a feeling. Only then does the last entry get metal. The rare miss is exactly why the year-later re-audit exists, and it is walked free.
Is any of this legal — bats especially?
Every species on this page is protected by some rule and we work inside all of them — bats most of all: no exclusion between the spring births and the flight of the pups, because sealing flightless young in is both illegal and unforgivable. Raccoon families are handled under the season rules too, kits always with a route back to the mother. The law is a floor; our calendar mostly sits above it.
What does the attic restoration involve?
Containment first — the hatch sealed and the work under negative pressure where guano loads justify it — then droppings and nesting out, biological odour neutralization rather than perfume, and insulation blown back to the specified depth. We photograph the before for you and the after for us, and the air above your ceiling goes back to being nobody’s business but yours.
Will they come back?
The animal that left cannot re-enter — metal, not memory, is what stops it — and the year-later audit re-walks every closure to prove nothing has weathered open. What exclusion cannot promise is that a different animal never looks at your roof line with interest; that is what the map, the caps and the trimmed branches are for, and it is why 0.9 percent, not zero, is the honest number on the sign.

Draw the line at the attic
What you hear, where, and at what hour — the species is usually identifiable from the racket alone. The audit comes with a map and a fixed quote, and the door goes up the same week in season. door@denline.example
