Millipede and Centipede Jobs: The Fall Invader Call You Can Upsell

It's the second week of October and your phone buzzes with a photo. A homeowner's garage floor has forty little brown coils on it, and one caption: "What are these and can you come today?" You zoom in. Millipedes. And in the corner of the shot, blurry and fast, something with a lot more legs — a house centipede that bolted the second the flash went off.

Most operators quote this call in about eight seconds. "Ninety bucks, I'll spray the perimeter." Then they drive out, hit the foundation with a general-use product, collect the check, and feel good about a fast, clean job. Three weeks later the same customer texts another photo. Now you're driving back for free, and the job you thought made $90 actually made about $12 an hour once you count the round trip.

Fall invader calls are some of the easiest money in the business — but only if you stop treating them like a one-and-done spray. Here's how I run millipede control jobs so they stay profitable and don't turn into a callback machine.

Why these calls spike in the fall (and why that matters for pricing)

Millipedes, centipedes, sowbugs, and their cousins are what the industry calls occasional invaders. They live outdoors in damp leaf litter, mulch, and soil, breaking down decaying plant matter all summer. When fall arrives and the ground starts to dry and cool, they go looking for moisture and stable temperature — and the crawlspace, garage, and slab edge of a house is exactly that.

That's the key insight for pricing: the bugs on the garage floor aren't the problem. They're the overflow. For every millipede curled up on the concrete, there are hundreds in the mulch bed and along the foundation. A spray on the visible ones is theater. If you don't treat the source and the entry points, the pressure outside just refills the inside.

So when a homeowner asks "can you just spray the ones in the garage," the honest answer — and the one that protects your margin — is no. You're pricing a perimeter and entry-point job, not a floor spray.

What the job actually is

Run it as a defined visit, the same way every time, so you can price it confidently:

1. Walk the exterior first

Before you touch a sprayer, walk the foundation. You're looking for the moisture that's drawing them in: mulch piled against the siding, leaf litter in the beds, a downspout dumping water at the corner, a crawlspace vent with no screen. Half of these calls are really a conducive-conditions conversation. Note it, tell the customer, and you've just justified your price and set up the recurring pitch.

2. Treat the perimeter and the harborage

Hit the foundation band, the first few feet of soil and mulch out from the house, and the harborage — under the deck, along the retaining wall, the shady damp side. This is where the population lives. A crack-and-crevice and exterior band application here does the real work.

3. Seal and treat the entry points

Garage door thresholds, weep holes, the gap under the man-door, crawlspace access, dryer vents. Centipedes especially come through gaps you'd never spray. Even a quick note to the customer — "get a rubber seal on that garage door" — turns you into the pro who solved it, not the guy who sprayed and left.

Centipedes are worth a word here. They're predators, not plant-feeders, and they show up because there's prey: the millipedes, silverfish, and other invaders already inside. Knock down the food supply with the perimeter work and the centipedes leave on their own. Customers panic about the leggy ones the most, so being able to explain that on-site builds real trust.

Pricing it so you don't lose money

Stop quoting the one-time spray number. A fall invader job with a real perimeter and entry-point treatment should run $125–$175 for most solo operators, more with a crawlspace, a big lot, or heavy moisture issues. That price has to assume you might come back once, because sometimes you will — a heavy population takes a knockdown plus a follow-up.

But the better move is to not sell a one-time at all. Sell the pattern.

Because here's the truth about these houses: if the property backs up to woods, sits on a damp slab, or has mulch beds hugging the foundation, the customer will see invaders every single fall. That's not a one-time customer. That's a recurring customer who doesn't know it yet. When you're standing in the driveway explaining why they're getting them, you're perfectly positioned to say: "I can knock these down today, but you'll see them again next fall for the same reason. A quarterly plan keeps the perimeter treated so they never make it inside — want me to price both?"

Quote the plan first. Let the one-time be the fallback, not the default. You'll convert a surprising number of these, because you've earned it by explaining the problem honestly instead of just spraying.

Don't let the callback eat the profit

The reason these jobs go bad isn't the pest — it's the return trip you didn't price for. If you run five fall invader calls this week as $90 sprays and two of them call you back, you drove ten times for the revenue of five jobs. That's how a "good week" quietly becomes a break-even one.

The fix is boring and it works: price to cover a possible return, document what you treated and the conducive conditions you flagged, and set a follow-up expectation up front. A visit note that says "downspout dumping at NW corner, recommended extension, treated perimeter + garage threshold" is the difference between a confident callback conversation and an argument.

This is the kind of thing a good system quietly handles for you — I keep every visit, photo, and note in PestPro Smart CRM so when a fall invader customer calls back next October, the whole history is right there and the recurring plan is one tap to schedule. But the tool isn't the point. The habit is: run the same defined visit every time, price for the return, and sell the pattern instead of the spray. Do that with a notebook and you'll still beat the operator with the best software who's out there spraying garage floors for ninety bucks.

Fall gives you a steady stream of these calls for eight or ten weeks. Run them right and they're not cheap one-time work — they're next year's recurring route, showing up at your door and asking you to come today.
