Cold preserves, it doesn't dissolve
The most common winter assumption is that waste "goes away" in the cold. The opposite is true. Freezing halts microbial breakdown almost entirely, so what lands on your lawn in December is essentially still there in March — just harder, flatter, and buried under leaves and snowmelt.
What actually happens over a NOVA winter
A two-dog household skipping December through March accumulates roughly 180 pounds of waste in the yard. Northern Virginia's freeze-thaw cycling makes it worse: each thaw partially softens the surface, waste settles into the turf, and the next freeze locks it there. By spring you're not scooping off the grass, you're prying out of it.
The thaw is when the bacteria move
Snowmelt and early spring rain carry a winter's worth of accumulated bacteria into storm drains all at once. That's precisely why local watershed programs flag pet waste as a nonpoint source pollutant. In Arlington that runoff heads toward Four Mile Run; in Fairfax much of it drains into Accotink Creek; in Reston it ends up in the lakes.
Pathogens survive the cold too
Parvovirus can persist in soil for up to a year, and roundworm eggs survive freezing without difficulty. A winter of accumulated waste is a spring yard that isn't safe for a puppy or a toddler until it's cleared.
The economics
Pausing four months of every-other-week service saves eight visits. The catch-up clean it creates usually costs more than those visits did, takes far longer, and leaves the yard unusable in the meantime. That trade rarely works out in your favor.
What winter service actually looks like
We run through the winter. Snow cover is the only real limitation — if there's more than a few inches on the ground we'll reschedule rather than pretend we did a thorough job. Frozen waste comes up cleanly; buried-under-snow waste doesn't, and we'd rather come back than charge you for a visit that missed half the yard.
Yards in wooded areas like Oakton are the most vulnerable, because leaf litter hides the accumulation completely until spring. If your yard is already in that state, a catch-up clean is the fastest way back to normal.
