IPM, Fumigation & Stored-Product Pest Control in Wisconsin
Wisconsin is America’s Dairyland — the #1 cheese state, making about a quarter of all U.S. cheese, the national leader in corn for silage and in cranberries, and home to a food-processing sector worth roughly $107 billion that employs nearly 300,000 people. Corn is the top crop by value, and the state’s enormous dairy and livestock base keeps feed grain moving through mills and bins year-round. From the cheese plant and feed mill to the elevator and farm bin, FSS keeps Wisconsin product clean, compliant, and inspection-ready — and that is the only thing we do.
45+ years of stored-product expertise. Founded in 1981, FSS specializes in stored-product protection, not general pest control. We hold one of the highest concentrations of certified entomologists in the industry: 3 Board Certified Entomologists (BCE), 11 Associate Certified Entomologists (ACE), a Ph.D. entomologist, research scientists, and OSHA-authorized trainers. Our team helped pioneer practical alternatives to methyl bromide during the global Montreal Protocol phaseout — work that took our founder around the world as a United Nations methyl-bromide phase-out advisor and earned recognition from the U.S. EPA for leadership in ozone protection — and has trained thousands of grain and food-industry professionals worldwide. That depth shows up in your plant, your bins, and your audit file.
The Pests That Threaten Wisconsin Grain & Food Plants
Across cheese and food plants, feed mills, elevators, and farm bins, the same stored-product complex drives the risk. Primary (internal) feeders — the granary, rice, and maize weevils, the lesser grain borer, and the Angoumois grain moth — develop inside sound kernels and are the hardest to detect. External and food-facility pests work broken grain, dust, flour, and finished product: the red and confused flour beetles, sawtoothed grain beetle, and the Indianmeal moth — the most common stored-food moth, and a frequent problem in food and feed facilities. In a high-sanitation environment like a cheese or food plant, those insects are exactly what an auditor looks for, which is why monitoring and IPM come first and fumigation resets an entrenched problem.
IPM & Fumigation Services for Wisconsin Operations
FSS protects Wisconsin operations through three integrated tiers:
- Integrated Pest Management (IPM) — documented, monitoring-based programs for cheese/dairy plants, food and feed facilities: remote rodent and insect monitoring, pheromone trapping, sanitation and exclusion guidance, and root-cause analysis that keep plants inspection-ready and reduce reliance on broad-spectrum chemicals.
- Structural fumigation — ProFume® (sulfuryl fluoride) for flour mills, food and pet food plants, feed mills, and warehouses on coordinated shutdown schedules, eliminating every life stage of stored-product insects throughout the structure.
- Grain fumigation — commercial and terminal-elevator phosphine fumigation (aluminum phosphide and cylinderized VaporPhos®, Eco2Fume®) with recirculation (J-System), verified with gas-concentration monitoring across the grain mass.
All three tiers are backed by gas monitoring and equipment calibration so results are verified, not assumed.
Built for audit readiness in Wisconsin. Grain dealers and warehouse keepers are licensed by the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), and fumigation is performed only by DATCP-certified applicators, with a written Fumigation Management Plan on every aluminum/magnesium phosphide job and support for FDA FSMA preventive controls and GFSI audits (SQF, BRC). We serve food, feed, and grain operations across the state of Wisconsin.
