IPM, Fumigation & Stored-Product Pest Control in South Dakota
Corn is South Dakota’s #1 crop at over $4 billion, alongside major soybeans and the state’s standout oilseed: South Dakota is #2 in the nation for sunflower production. That grain and oilseed feed a growing in-state processing base — soybean and sunflower crush plants in Aberdeen and Mitchell, one of the country’s largest ethanol industries, and 3.5 million head of cattle driving feed demand. From the food and feed plant and oilseed crush to the elevator and farm bin, FSS keeps South Dakota 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 South Dakota Grain, Oilseeds & Food Plants
Across food plants, feed mills, crush facilities, elevators, and farm bins, the same stored-product complex drives the risk. Primary (internal) feeders — the granary, maize, and rice weevils, the lesser grain borer, and the Angoumois grain moth — develop inside sound kernels and are the most destructive. External and food-facility pests work broken grain, dust, and finished product: the red and confused flour beetles, sawtoothed grain beetle, flat grain beetle, cadelle, and the Indianmeal moth — the key pest for stored oilseeds and food/feed facilities. (Note: sunflower-head pests like the sunflower moth and red sunflower seed weevil are field pests, not stored-product insects.) SDSU Extension’s message is prevention-first: cool, dry, monitor — then fumigate to reset an entrenched population.
IPM & Fumigation Services for South Dakota Operations
FSS protects South Dakota operations through three integrated tiers:
- Integrated Pest Management (IPM) — documented, monitoring-based programs for food, feed, and crush 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, oilseed processors, and warehouses on coordinated shutdown schedules, eliminating every life stage of stored-product insects throughout the structure.
- Grain & oilseed 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 South Dakota. Public grain warehouses and buyers are licensed by the South Dakota Public Utilities Commission, and fumigation is performed only by applicators certified through the South Dakota Department of Agriculture and Natural Resources (DANR), 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 South Dakota.
