Monthly weed control appointments provide the most effective control and suppression.  With consistent appointments from Northwest Exterminating, we can eliminate weeds and prevent them from growing back around your office building, retail store, manufacturing complex, government facility or home.

  • Pre-emergent weed control is an application that stops weeds before they start.
  • Post-emergent weed control is an application that kills existing weeds.
  • Soil sterilents stop all weed growth for long periods of time (restrictions apply).
  • Maintenance service agreements and extended warranties are available.

Pre-Emergent Weed Control

  • Liquid application
  • Low to no odor
  • Non-staining
  • Safe on existing plants
  • Restricts weeds from germinating (will not kill existing weeds)

Post-Emergent Weed Control

  • Rain-fast as soon as product dries
  • Absorbs into leaves, stems and roots
  • Effects on weeds will take 3-7 days
  • Product is only applied on weeds
  • Topical treatment
  • Blue dye will fade away within 3-4 days

If weeds are well developed, physical removal may be your first course of action. Remember though that this is only a temporary solution. The physical removal of weeds can be tedious, so that is why Northwest Exterminating is here for you!

customer for brown recluse spider control in cochise county


‟I bought a home, sight unseen (I trusted a VA inspector) in rural Cochise County, AZ.
After moving in I quickly discovered that the home was INFESTED with vermin and BROWN RECLUSE SPIDERS!

NW Exterminating installed ‘Desert Guard’ and that took care of ALL of the vermin, and, after a few treatments of Spider Power-Dusting in my crawl space I am free of dangerous spiders!
