Spot Treatment vs Broadcast
Choosing between targeted applications to specific areas (spot) versus wide-area coverage (broadcast) based on pest distribution and label restrictions.
Detailed Overview
Spot treatment applies pesticide to small areas (2 square feet or less per label definition) where pests observed or expected. Broadcast treatment covers larger floor or wall areas. Label language critical - some products labeled for crack-and-crevice and spot only, never broadcast. Most IPM programs prohibit broadcast sprays inside occupied spaces due to excessive exposure. Spot treatments appropriate for: localized German roach infestations in specific cabinets, ant trails along baseboards, individual rodent entry points being sealed, bed bug harborage sites. Broadcast appropriate for: empty units before move-in, warehouse floors with widespread roach populations, outdoor turf for grub control, commercial kitchens after hours when cleared. Modern professional practice favors targeted applications over broadcast. Exception: some product labels require broadcast application to achieve labeled control (flea treatments to carpets, some turf applications). Regulatory trend toward limiting broadcast applications indoors. Food facilities typically prohibit broadcast applications except in specific circumstances. Know label language: crack-and-crevice (into cracks only, product not visible after application) vs spot (up to 2 sq ft) vs broadcast (larger areas).
When to Use
Default to spot and crack-and-crevice treatments for all indoor applications. Use broadcast only when pest distribution warrants, label permits, and customer situation allows (vacant units, after-hours commercial).
Required Skill Level
Should only be performed by licensed pest management professionals
Benefits
- Spot treatments minimize pesticide exposure
- More acceptable for IPM and sensitive accounts
- Often more effective by concentrating product where pests live
- Uses less product reducing costs
- Complies with label restrictions
- Reduces environmental impact
Limitations
- Spot treatments may miss scattered populations
- More labor-intensive than broadcast
- Requires thorough inspection to identify all spots
- Some pests may require broadcast for adequate control
