Every October the maples drop a blanket over the yard, and everything your dog left out there disappears under it. Out of sight is not out of the yard. Here is how to clean up in the right order.
Scoop first, then deal with the leaves. Raking, blowing, or mulch-mowing over dog poop does not get rid of it. It breaks it up and spreads it across the lawn and into your leaf bags. In Pierce County, leaves go in the yard waste bin, but pet waste is not accepted there and does not belong in a home compost pile either. Bag it and put it in the trash.
Here is a fall ritual most dog owners know. You haul out the rake, you make it three strides across the lawn, and you feel that unmistakable squish through a pile of wet maple leaves. Suddenly the whole project needs a hose, a new plan, and possibly new shoes.
That squish is a small preview of a bigger problem. Pierce County estimates its more than 206,000 dogs produce more than 68,000 pounds, or 34 tons, of waste every single day.1 The City of Bonney Lake puts it at as much as 1,000 pounds a day in a city our size.3 Plenty of that is sitting in backyards right now, under a fresh layer of leaves.
When you can see it, you pick it up. When it is buried under leaves, it sits there for weeks in exactly the conditions parasite eggs like best.
The Companion Animal Parasite Council says roundworm eggs are hardy and can survive for years. They become infective after 2 to 4 weeks in the environment.5
One adult roundworm can shed that many eggs a day, and common disinfectants do not kill them.5
Eggs stay viable for several years in moist, shaded, cool soil. Sunlight and drying kill them.7 A mat of wet leaves is basically a shade tent.
Two to four weeks is roughly how long leaves sit on a lot of lawns before anyone gets to them. That timing is not great. We covered the reinfection side of this in why dogs keep getting parasites after treatment, and the full list of what lives in dog waste in why dog waste is a real health risk.
About the leaf pile: the CDC says dog poop should be picked up even in your own yard, "especially in areas where children may play," and kids are most often infected with roundworm by accidentally swallowing contaminated dirt.8 6 9 Before anyone cannonballs into the big leaf pile, make sure it was raked from a yard that got scooped first.
Mulch-mowing leaves back into the lawn is genuinely good lawn care, and we will get to it. Doing it over unscooped ground is not. A mower does not remove a pile. It chops it into smaller pieces and spreads them over more grass. A leaf blower does the same thing sideways. CAPC notes that parasite eggs remain in the environment even as feces decompose or get dispersed.5 Spreading it out just means more square feet to worry about.
Pierce County's curbside yard waste program accepts leaves and specifically lists pet waste as not accepted.2 Yard waste gets composted, and pet waste does not belong in that stream.
Leaves are great compost. Dog waste is not. Pierce County notes most compost piles do not get hot enough to kill the bacteria, and WSU Extension says a pile needs to hold around 140 degrees for an extended time to kill pathogens like E. coli and Salmonella, which home piles rarely manage.1 4 That compost ends up on the vegetable beds. Hard pass. (For the record, dog poop is not a lawn fertilizer either. We did a whole post on that myth.)
A good tool makes step one much less miserable. A rake and tray set handles leaf-covered grass far better than a clamp-style scooper. Our guide to pooper scooper tools covers what works.
| Item | Yard waste bin | Home compost | Trash |
|---|---|---|---|
| Clean leaves | Yes | Yes | Not needed |
| Dog poop | No | No | Yes, bagged |
| Leaves mixed with poop | No | No | Yes, bagged |
| Cat litter | No | No | Yes, bagged |
Pierce County's position is simple: bag it and trash it, because landfills are designed to handle pet waste safely.1 Rain that runs across an unscooped yard carries bacteria toward streams and storm drains, which is the whole idea behind the county's "Clean Paws. Clean Lawns. Clean Streams." campaign.1 Our post on dog waste and water quality follows that runoff all the way to Lake Tapps.
Once the yard is scooped, it is a good time to plan repairs for the damage summer left behind.
If your dog tends to pick the same few spots, now is also a great time to start training a single potty area. Fewer spots means less leaf-hunting next year.
We scoop before the leaves pile up and keep scooping while they fall, so by the time you get out there with the rake, the only thing under the leaves is lawn. Leaf it to us, basically. We will see ourselves out.
The short version: scoop, then rake. Poop goes in the trash, never the green bin or the compost. Keep up with it weekly while the leaves are falling, and give the kids a leaf pile that is actually safe to jump in.
No. Pierce County's curbside food and yard waste program lists pet waste as not accepted. Bag dog waste and put it in the regular trash. Leaves are fine in the yard waste bin as long as they are not mixed with poop.
It is not a good idea. Most home compost piles do not get hot enough to kill the bacteria and parasites in dog waste. WSU Extension notes a pile needs to hold around 140 degrees for an extended time. Scoop first, then compost the clean leaves.
Mowing does not remove it. It breaks waste into smaller pieces and spreads it across more of the lawn, and parasite eggs stay in the soil as it breaks down. Scoop before you mow or mulch leaves.
Roundworm eggs can stay infective in soil for months or even years, according to the Companion Animal Parasite Council and the CDC. They last longest in cool, moist, shady soil, like the ground under a layer of wet leaves.
Not in a thick layer. WSU warns heavy leaf cover can smother turf over winter. Mulch-mowing thin layers every few days, or raking and bagging, keeps the lawn healthy.
WSU King County Master Gardeners recommend overseeding thin areas in September or October, with spring as a second window. Water the spots heavily and overseed with a seed mix that matches your lawn.
