Tubular Droppings in the Garden: Raccoon, Opossum, or Skunk?

Tubular droppings in a garden bed most often come from raccoons, opossums, or skunks raiding for produce, grubs, and insects — though garter snakes and even toads leave surprisingly substantial droppings too. Blunt ends and berry seeds point to raccoon, tapered curves to opossum, and a crumbly texture full of shiny insect parts to skunk. Because raccoon droppings can carry roundworm eggs, droppings in a food garden also raise a produce-safety question worth taking seriously.

Most likely causes

  • Raccoon — tubular with blunt ends, berry seeds or corn visible, sometimes a repeat latrine spot
  • Opossum — larger tapered or curled droppings left near feeding damage
  • Skunk — crumbly droppings glittering with undigested insect shells, plus small grub-dig holes
  • Garter snake — a dark elongated smear with a white chalky cap, semi-liquid rather than formed
  • Toad — a surprisingly large, dark, moist cylinder for such a small animal, near mulch or a damp hiding spot

Compare the possible causes

Possible cause Key signs When it happens How likely
Raccoon Segments 2–3 inches long, about 3/4 inch thick, with blunt broken-looking ends and visible seeds, corn, or shiny insect bits Overnight raids peak in late summer as corn, tomatoes, melons, and berries ripen Very common
Opossum Smooth droppings up to 2–3 inches, often tapered or curled, near knocked-down fruit or a raided compost pile Year-round nighttime visits, more frequent when fallen fruit or compost is available Common
Skunk Tubular but fragile droppings 1–2 inches long that crumble when nudged with a stick, flecked with shiny insect wings and shells, near small cone-shaped dig holes Nightly grub hunting, heaviest late summer through fall when grubs ride near the surface Common
Garter snake An elongated dark smear or soft cord with a white chalky cap on one end, deposited on soil, mulch, or a stepping stone Warm months, most often near sunny basking spots and dense ground cover Less common
Toad A dark, moist cylinder up to an inch or more long — startlingly large for the animal — found near mulch, a downspout, or under leafy cover Warm, humid nights spring through early fall Less common

Visual clues to check

  • Check the ends with a stick, never fingers: blunt ends suggest raccoon, tapered or curled ends suggest opossum
  • Look for sparkle: shiny insect wings and shell fragments throughout the dropping point to skunk (or toad, if it's a single uniform cylinder)
  • Scan for seeds: berry seeds and corn kernels are the raccoon's menu written in evidence
  • Look for a white chalky cap on one end — reptile sign, most likely a garter snake
  • Survey the surrounding damage: cone-shaped dig holes mean skunk; raided corn, hollowed melons, or half-eaten tomatoes mean raccoon or opossum
  • Check whether droppings recur in one spot: a growing multi-age pile at the bed's edge is a raccoon latrine
  • Inspect at dawn — fresh moist droppings mean the animal visited hours earlier and will likely return tonight

The causes in detail

Raccoon

A vegetable garden in August is a raccoon buffet, and raccoons often leave droppings right where they feed — or worse, establish a latrine at the garden's edge, on a raised-bed corner, or atop a nearby stump, where droppings of different ages accumulate. Raccoon feces are the serious one here: they can carry raccoon roundworm eggs that remain infectious in soil for years, which is why droppings in a bed where food grows warrant careful cleanup, not a quick flick with the trowel.

Opossum

Opossums amble through gardens eating fallen fruit, slugs, snails, beetles, and the occasional low tomato, leaving dog-like droppings that taper at the ends where raccoon droppings stay blunt. They rarely do serious plant damage, and their appetite for ticks and slugs means many gardeners quietly tolerate them. Their droppings still don't belong in a food bed, but they don't carry the roundworm concern raccoon droppings do.

Skunk

Skunks come to gardens for the insects, not the vegetables — beds rich in grubs, beetles, and earthworms get patrolled nightly. The dropping's crumbly texture and glittering insect fragments are diagnostic, and the accompanying evidence seals it: neat little cone-shaped holes an inch or two across dug in mulch and soil where the skunk extracted grubs. Skunk visits often taper off on their own once the grub supply thins.

Garter snake

Snake droppings surprise people because they aren't pellet-like at all — they're semi-liquid, elongated, and carry the white uric-acid cap that reptiles share with birds. A garter snake living in your garden is eating slugs, grasshoppers, and rodents, making it one of the best pest controllers you can host. Garter snakes are harmless to people; the dropping is just a sign your garden has a healthy food web.

Toad

Toad droppings are a classic garden mystery: a single toad eats enormous numbers of insects nightly and produces droppings so large that homeowners assume a much bigger animal was responsible. The dropping is uniform, dark, and moist when fresh, usually near where the toad shelters by day — under a deck edge, a flower pot, or thick mulch. A resident toad is pure upside; leave it be and take the free pest control.

When to worry

  • A raccoon latrine forming in or beside a bed where food grows — a roundworm contamination issue, not just a nuisance
  • Droppings appearing nightly along with escalating crop damage as harvest approaches
  • Droppings in beds where children dig and play
  • A pet that has eaten or rolled in garden droppings — worth a call to your vet
  • Any animal seen in the garden by day acting disoriented or fearless

What to do now

  1. Remove droppings promptly wearing gloves: scoop with a dedicated trowel, take an inch of surrounding soil with it, and dispose in a sealed bag in the trash — never the compost
  2. Wash all garden produce thoroughly under running water before eating, and peel or cook anything that grew in direct contact with contaminated soil
  3. If a raccoon latrine has formed, have a wildlife professional clean it, or follow CDC latrine protocols exactly — for a food garden, professional decontamination is the conservative call
  4. Harvest ripening produce promptly and pick up fallen fruit daily; an empty buffet loses its customers
  5. Exclude raiders with a low electric fence (two strands at 4 and 8 inches works well for raccoons) or sturdy hardware-cloth cages over prized beds
  6. Skip the food rewards elsewhere too: secure trash and compost, and bring in pet food overnight
  7. If nightly raids continue despite exclusion, contact a licensed wildlife control operator rather than trapping on your own

What not to do

  • Don't handle droppings bare-handed or flick them aside with the same trowel you harvest with
  • Don't till droppings into the bed or add them to compost — home compost doesn't reliably kill roundworm eggs or pathogens
  • Don't eat unwashed produce from a bed where droppings appeared, even fruit that looks untouched
  • Don't kill garter snakes or toads found near the droppings — they're likely eating your actual pests
  • Don't set leg-hold traps or poison baits in a garden; both are dangerous, and trapping wildlife is regulated in most states

Frequently asked questions

Is my garden produce still safe to eat?

Generally yes, with precautions. Remove the droppings and adjacent soil, then wash everything under running water; peel or cook produce that touched contaminated soil directly. Discard anything an animal bit or that was lying against the droppings themselves. If a raccoon latrine sat in the bed for a while, be more conservative — decontaminate first and consider writing off that bed's low-growing crops for the season.

How can I tell raccoon droppings from opossum droppings?

Ends and habits. Raccoon droppings are uniform tubes with blunt, broken-off ends, usually studded with seeds, and raccoons often return to the same latrine spot so droppings accumulate. Opossum droppings taper or curl at the ends, tend to appear singly near feeding damage, and don't build up in one place.

I found a huge dropping but only ever see a toad in that bed. Could it really be the toad?

Very possibly. Toads eat hundreds of insects in a night and produce droppings dramatically out of proportion to their size — a dark, moist cylinder an inch or more long is well within range. If the dropping is uniform in texture, appears near a daytime hiding spot like a pot or mulch pile, and there's no other animal sign, the toad is your answer.

Will a fence keep these animals out of the garden?

It depends on the animal. Raccoons climb ordinary fencing easily — a low two-strand electric fence or a floppy-top design works far better. Skunks don't climb but do dig, so fencing needs a buried skirt. Opossums are deterred by most decent fences. For a few prized beds, hardware-cloth cages or hoop covers are simpler and utterly reliable.

Droppings under a deck usually mean an animal is using the space as a den, not just passing through — most often a skunk, opossum, feral cat, or raccoon, and occasionally a groundhog. Skunk droppings are crumbly and full of shiny insect parts, opossum droppings are large and curved, cat droppings are often buried in loose soil, and a pile of tubular droppings in one corner is a raccoon latrine that needs professional-level caution. Timing matters: from spring into midsummer, most of these animals have babies down there. Read the guide → Animal Droppings Small Pellet Droppings in Yard: Rabbit, Deer, or Squirrel? Small pellet droppings scattered across a yard are most often left by rabbits, deer, or squirrels. Rabbits drop round, pea-size pellets in loose clusters on the lawn, deer leave larger oval pellets in concentrated piles of 20 or more, and squirrel droppings are barrel-shaped and scattered under trees. Where the pellets show up — open lawn versus garden edge — is as telling as their shape. Read the guide → Animal Droppings Black Droppings on Your Patio: Rat, Mouse, Bat, or Bird?
