The Bug Side of House Washing (It’s Bigger Up Here)
Nobody budgets for "bug washing," but on houses near the big lake it's a real fraction of what we remove. Lake Superior's insect cycles — the mayfly and midge hatches, and the spider boom that follows them — coat near-shore buildings in webbing, egg sacs, and droppings at a rate inland homeowners wouldn't believe. Here's what's actually on the house, what washing does about it, and the one nest-related rule that keeps everyone unstung.
The Lake Superior Insect Economy (As It Applies to Your Siding)
Spiders are the headline. Lake hatches mean near-shore walls are all-you-can-eat buffets, so spiders colonize eaves, soffits, light fixtures, and window frames in densities that turn corners gray with webbing by August. Worse than the webs are the droppings — small dark specks concentrated below web sites that bond to siding like paint spatter. Mayflies and midges die against walls by the thousand in hatch weeks, leaving an organic film that feeds the algae cycle. Wasps and hornets build in soffit gaps, behind shutters, under deck rails — relevant to washing because a wand hitting an unnoticed nest is the worst minute of anyone's summer. Box elder bugs and Asian beetles stage on warm south walls each fall and leave droppings and a defensive-secretion stain when disturbed in numbers.
What Washing Actually Does
| Problem | Wash result |
|---|---|
| Webbing & egg sacs | Removed completely — soft wash chemistry dissolves the silk anchors pressure alone smears around |
| Spider droppings | Mostly to fully removed with dwell time; old accumulations on porous surfaces may ghost |
| Insect body film | Removed — this is also algae prevention, since the film is fertilizer (the chain explained) |
| Future activity | Honestly: reduced, not prevented. A washed house removes the scent trails, anchors, and food film — spiders rebuild slower on clean siding — but washing isn’t pest control and we won’t pretend otherwise |
The Wasp Protocol
We walk the house before washing specifically looking for active nests — soffit gaps, shutters, meter boxes, play structures, grill covers. Small accessible paper nests early in the season are manageable; established colonies in wall voids or large aerial nests get flagged and left to you or a pest professional, and we wash around them or reschedule that section. A pressure wand is not a wasp-removal tool, no matter what the internet's most confident men believe.
FAQ
Does house washing remove spider webs and droppings?
Yes — chemistry dissolves anchors and lifts droppings. Very old accumulations may ghost slightly.
Will washing keep spiders away from my house?
Reduces, doesn’t prevent. Clean siding recolonizes slower, but lake hatches guarantee they return.
What happens if there’s a wasp nest where you’re washing?
We find them first. Small early nests are manageable; real colonies go to pest pros — never the wand.
