What Rides In On The Truck: Checking Inbound Freight For Pests

A delivery is the one pest entry route you can inspect before it is inside. A trailer, a pallet and a case each carry something different, and two minutes per load at the dock catches the obvious cases while the stock still belongs to somebody else. Here is what to look at, and what the federal rules already expect of you.

Stark and Summit counties run on freight. Food plants, distribution centers, a machine shop with a back door and three pallets of corrugate stacked against the wall. Receiving is where the two halves of a pest program meet: everything outside the building is exclusion work, everything inside is monitoring, and the dock sits in the gap between them. The useful part is that the gap is staffed.

What Can Actually Ride In On A Load

Five things turn up often enough to be worth a named check. What you would see depends entirely on where the insect is riding, which is why a glance at the shrink wrap tells you so little.

The cardboard row is the one people argue with. University of Minnesota Extension is direct about it: German cockroaches are usually brought into buildings inside infested boxes, bags, luggage and other items, and they can be found indoors at any time of year. They do not walk across a parking lot in February. Something carries them. Our guide to telling the species apart matters here, because a German cockroach on a receiving dock is an introduction and a large dark one near a floor drain usually is not.

What The Rules Already Ask Of Receiving

If you make or hold human food, the receiving inspection is not a best practice you can adopt at your leisure. It is written into the preventive controls rule. Under 21 CFR 117.80(b)(1), raw materials and other ingredients must be inspected and segregated or otherwise handled as necessary to ascertain that they are clean and suitable for processing, and stored under conditions that protect against contamination and minimize deterioration.

The pest line follows right after it. Section 117.80(b)(4) covers raw materials, other ingredients and rework that are susceptible to contamination with pests, undesirable microorganisms or extraneous material, and requires them to comply with the FDA regulations for natural or unavoidable defects before a manufacturer uses them in food. Those regulations are where the phrase defect action level comes from, defined in part 117 as a level of a non-hazardous, naturally occurring, unavoidable defect at which FDA may regard a food product as adulterated. Live insects moving on a pallet in the receiving bay are a different conversation. That is an incoming load you can still hold.

Food service sits under the other code and lands in the same place. Ohio Revised Code 3717.05 requires the state uniform food safety code to be based on the current FDA model Food Code, and Food Code 3-202.15 requires food packages to be in good condition and to protect the integrity of the contents so the food is not exposed to adulteration or potential contaminants. A chewed corner on a case of flour fails that sentence on its own. For the audit paperwork that sits behind all of this, our food plant audit guide covers the documentation set, and the food manufacturing page covers the program itself.

The Pallet Stamp, And What It Does Not Cover

Wooden pallets carry a treatment mark, and it is routinely read as a clean bill of health for the whole load. It is narrower than that. USDA APHIS describes the standard for wood packaging material as heat treatment to 56 degrees Celsius at the core for at least 30 minutes, or fumigation with methyl bromide to the ISPM 15 schedule, with a mark that carries the IPPC symbol, a two letter country code, a facility number and the treatment code, HT or MB.

So the stamp answers one question: whether the wood itself was treated before it was marked. It says nothing about what settled on that pallet in a yard three months later, nothing about the product stacked on top of it, and nothing about the trailer it rode in. Read it as the wood question closed and the pallet question still open.

A Two Minute Check, In Order

Receiving staff do not need to identify insects. They need to know what makes a load worth a second look, and they need somewhere to write it down.

1. Look into the trailer before anything comes off it, with a light. Front wall, floor corners, under the first row.
2. Use your nose. A musty smell in a dry load, or an ammonia note, is worth the extra minute.
3. Check the pallet from the side and underneath: exit holes, powder, insects pressed into the joint between deck board and stringer.
4. Run a hand span along case seams and sack folds, where webbing and fine grit show up first.
5. Look for gnawing and droppings along the outside edges of the load, where a rodent would have travelled.
6. Pull the one case nobody checks, the bottom layer at the back of the pallet.
7. Record the load as checked, including the clean ones. A log with only exceptions in it proves nothing to an auditor.

From October through to spring, add one glance for egg masses on the pallet, the equipment and the trailer itself. Penn State Extension puts it as plainly as anyone: the spotted lanternfly can hitchhike on any object at any life stage, which is why state orders in the quarantine states ask that vehicles, trailers and equipment be inspected and egg masses removed before anything moves. Ohio is inside that picture now. The Ohio Department of Agriculture took its quarantine statewide on February 17, 2026, as Ohio State University Extension reported at the time, so no Ohio county sits outside the zone any more, and a business moving regulated articles out of the state does it under a compliance agreement, a permit or an inspection certificate. What the insect looks like at each stage is in our spotted lanternfly guide.

When A Load Looks Wrong, Stop It Where It Is

The expensive mistake is motion. A pallet that goes to the rack while somebody decides turns a receiving problem into a facility problem, and the second one costs more to solve because it now involves everything the pallet was parked next to.

• Hold it in place or move it once, to a designated spot away from production and away from other stock. Sealed, if the load allows it.
• Photograph what you found, with the lot code, the bill of lading, the carrier and the time in the frame.
• Get it identified before anybody decides anything. An insect that lives in sealed packaged goods points back up the supply chain, and one that feeds on spillage points at your own storage. Our warehouse stored product pest guide walks that split.
• Let purchasing and quality make the call on the load, not the person holding the pallet jack at four in the afternoon.
• Do not reach for an aerosol. Pesticide labels are enforceable law, applying them in a commercial facility for hire is licensed work in Ohio, and a treated food pallet is a bigger problem than the beetles were. Our note on checking an applicator license explains who may do what.

One honest caveat about frequency. Checking every load at a high volume dock is not realistic, and a program that pretends otherwise gets abandoned in week three. A workable version is every load of susceptible goods, every load from a supplier with a history, and a sample of everything else, with the sampling rate written down rather than left to whoever is on shift.

The Rest Of The Dock

Inbound material is half of the receiving problem. The other half is the opening you create to accept it, which is a dock door standing open on a loading apron for most of a shift. Door sweeps, seals, the gap under a dock leveller and the lights above the door all belong to the same part of the program, and we cover them in our guide to doors, screens and flying insects and in commercial rodent management.

We build warehouse and manufacturing programs around that order: exclusion on the outside, monitoring inside, documentation that an auditor can follow, and a receiving check your own staff can run without a field guide. If you want someone to walk your dock with you and work out what the check should be for your loads, book it through our request a quote page or call 330-494-6199. State Termite has been doing this in Northeast Ohio since 1933, and commercial pest management covers how the rest of the program fits together.
