Prepare for Your Appointment

1

Secure All Trash Cans

Make sure all trash cans have tight-fitting lids. This removes a major food source that attracts wildlife.

2

Bring Pet Food & Water Inside

Remove all outdoor pet food and water bowls. These are magnets for raccoons, skunks, and opossums.

3

Note Activity Times & Locations

Record when and where you've spotted the animal. This helps your technician understand patterns.

4

Photograph Any Damage

Photos of holes, torn screens, chewed wires, or disturbed areas give your technician a head start.

5

Don't Attempt to Trap or Corner

Cornered animals can be unpredictable and may carry diseases. Leave removal to your technician.

6

Clear Access Points

Make sure your technician can reach crawl spaces, attic entries, and areas under decks where wildlife may be nesting.

Your technician will guide you on arrival.

Raccoons grow to trophy size when fed by humans. Never feed wildlife — it makes them bold, aggressive, and destructive to your property.

Did You Know?

Signs of Wildlife Activity

Scratching or thumping in your attic, knocked-over trash cans, torn soffit or vent screens, droppings on your deck or roof, and unusual odors under your home are all signs wildlife has moved in. Tracks in mud or dust near your foundation confirm the species.

What Attracts Them

Unsecured trash, pet food left outdoors, fallen fruit, and bird feeders are the top attractants. Wildlife also seeks sheltered denning sites — gaps under decks, unsealed crawl spaces, uncapped chimneys, and damaged attic vents all provide easy entry.

Health and Property Risks

Wildlife can carry rabies, distemper, leptospirosis, and parasites like fleas and ticks. Raccoons and squirrels destroy attic insulation and chew wiring (a fire hazard). Skunks burrow under foundations, and accumulated droppings create serious indoor air quality concerns.

When to Call a Pro

Contact a professional if you hear animals in your attic or walls, find a den under your home, notice an animal behaving aggressively or acting disoriented, or suspect babies are present. In California, trapping and relocating most wildlife without a permit is illegal.

Seasonal Patterns

Spring is baby season for most wildlife — raccoons, skunks, squirrels, and opossums all give birth between March and June. Fall brings a surge of animals seeking warm shelter for winter. Calls spike in these seasons as wildlife moves into attics, crawl spaces, and wall voids.

Prevention Tips

Secure trash with locking lids, bring pet food indoors at night, and pick up fallen fruit daily. Seal gaps under decks and porches with heavy-gauge mesh, cap chimneys, and screen attic vents. Trim tree branches at least 6–8 feet from your roofline to cut off roof access.

What You Can Do

Secure Trash & Compost

Use wildlife-resistant cans with locking lids. Raccoons, skunks, and opossums are drawn to easy food sources overnight.

Install Motion-Activated Lights

Most wildlife is nocturnal. Motion-activated lights and sprinklers startle and discourage animals from settling.

Close Off Access Points

Seal gaps under decks, porches, and crawl spaces with heavy-gauge mesh. Trim branches that overhang your roof by at least 6 feet.

Bring Pet Food Inside

Don't leave pet food or water bowls outdoors overnight. These are magnets for raccoons, skunks, and opossums.

Pick Up Fallen Fruit

Fruit trees attract wildlife. Collect fallen fruit daily and harvest ripe fruit promptly to reduce visits.

Use Sound Deterrents

Ultrasonic deterrents or talk radio in attics and crawl spaces discourage wildlife. Animals prefer quiet, undisturbed spaces.

What to Avoid

Don't Feed Wildlife

Feeding wild animals — even unintentionally — makes them lose fear of humans and encourages return visits.

Don't Use Poison

Poisoning wildlife is often illegal and harms pets, children, and non-target animals. It also causes animals to die in hard-to-reach places.

Don't Approach or Corner Animals

Cornered wildlife can bite or scratch. Even gentle-looking animals can carry diseases. Keep a respectful distance.

Don't Relocate Animals Yourself

In California, trapping and relocating most wildlife without a permit is illegal. Relocated animals often don't survive.

Common Questions

Pest Control Questions — Answered

What people ask most before scheduling pest control service.

Signs you need a pro: pests that keep coming back after DIY treatment, rodent droppings or gnaw marks, termite mud tubes, bed bug stains on bedding, or any pest that poses a health risk. When in doubt, an inspection costs nothing. Schedule a free inspection →
Usually no. Gel bait and exterior perimeter treatments don't require you to vacate. You'd only need to leave for fumigation or heat treatment — and we'll always let you know well in advance. What to expect during treatment →
Most interior and exterior treatments take 30–60 minutes for a standard home. Larger infestations, full exclusion work, or heat treatments take longer. We'll give you a time estimate when you book. Schedule a consultation →
For most pests, yes — with proper exclusion. Treating without sealing entry points only delays the problem. ATCO combines treatment with exclusion guidance to prevent re-entry, not just manage what's already inside. Our approach to permanent pest removal →
  • Clear under sinks, behind appliances, and along baseboards
  • Store food in sealed containers
  • Note where you've seen pest activity — trails, entry points, droppings
  • Keep pets in a separate area during interior treatment
Book your appointment →
Yes. ATCO uses targeted gel baits placed inside crevices — never surface sprays in living areas. Products are selected based on your specific pest and what's safest for your household. Our eco-friendly treatment methods →
