Wheels on the Bus Go Round (AKA: Pigs will fly)
Today’s blog post is about this recent article:
No, you aren’t in the wrong place, this is still about pest control. But why am I talking about pigs and swine farms?
Great question, thanks for asking!
When we think about pests invading a facility, we picture the usual suspects: a gap under a door, an open dock leveler, an unscreened vent, or a crack in the foundation. We focus so much energy on structural exclusion—and don't get me wrong, sealing up a building is vital—that we sometimes overlook the giant, motorized porcine Trojanus pulling up to our loading docks every single day.
I’m talking about vehicles.
In commercial accounts, from massive food distribution centers down to your neighborhood grocery store and corner bistro, goods are constantly on the move. And where goods move, pests follow.
Pests are sneaky, but they’re also lazy. Why trek across an asphalt parking lot in the heat or rain when you can hop aboard a climate-controlled delivery truck packed with delicious cardboard boxes, wooden pallets, and food scraps?
Vehicles act as biological expressways. A truck can pick up German cockroaches or stored product pests at a supplier facility, drive across three state lines, and deposit them directly into a grocery store stockroom or restaurant pantry. And it’s not just trucks moving between commercial sites:
Delivery Vans & Fleet Trucks: Frequently parked overnight near dumpster areas or woodlots where rodents, roaches, and spiders actively forage.
Pallets & Crates: The wooden structure of pallets offers perfect harborage for insects, and once loaded into a truck, they stay protected from weather and predators.
Personal Vehicles: Employee and vendor cars can transport bed bugs, cockroaches, and hitchhiking flies directly into staff breakrooms and locker areas.
In large commercial processing and distribution facilities, transit pests are a known audit nightmare. But the risk doesn't stop at the regional distribution center. In fact, by the time a shipment reaches a retail grocery store or a restaurant, those goods have likely been transferred between multiple vehicles and staging areas, multiplying the opportunities for hitchhikers along the way.
At a grocery store, a pallet of bagged pet food or flour sits in a truck for hours. They may even sit in the same truck! Indian meal moths or grain beetles hiding in the folds of the packaging take the ride, get unloaded onto the stockroom shelf, and suddenly you have a full-blown infestation that customer service has to explain.
At a restaurant, linen delivery trucks, produce crates, and daily food shipments are constant vectors. Bed bugs are easily transferred from the dirty linens to clean ones. Cockroaches love corrugated cardboard—it provides warmth, tight harborages, and glue to snack on. Bringing those boxes straight into a kitchen prep area is effectively rolling out the red carpet.
You can’t stop deliveries, but there isn’t time to unpack pallets and deeply inspect everything on them. So here’s what sites can do:
Inspect Before Unloading: Establish a dock inspection protocol. Inspect the interior of delivery trailers for signs of pests, droppings, or damaged packaging before moving product into the building. Using a flashlight (YES, provide flashlights for employees to do this!), quickly look at all pallets or goods coming off the trucks.
Break Down Cardboard Early: Avoid storing incoming shipping boxes in core kitchen or production areas. Unpack supplies in a receiving area, transfer goods to clean plastic or stainless containers, and immediately move cardboard out to a secure recycling bin.
Inspect the Fleet: If your business operates service vans, delivery trucks, or forklifts, include them in your pest management program. Vehicle cabs and cargo holds need regular cleaning, trash removal, and monitoring traps.
Dock Sanitation & Lighting: Keep loading dock doors closed when not in active use, clean up spills immediately, and ensure exterior dock lighting doesn't attract flying insects straight into open truck bays.
Managing pests isn't just about what's living around your perimeter—it's about managing everything that comes through the door.
Thousands of dollars are spent on high-tech exclusion products, door sweeps, and air curtains, only to leave a truck backed up to an open dock bay for three hours while the driver takes a lunch break. If you aren't auditing your incoming delivery chain and the cleanliness of the transit vehicles supplying your facility, you are leaving the front door wide open. Pests don't care how nice your facility is; if you transport them inside on a silver platter (or a wooden pallet), they'll make themselves right at home.
