Deciding What to Do > Pest Management Principles
Preventing pesticide resistance:
 
  • Use IPM
  • Use pesticides only when needed
  • Use pesticides that have different modes of action
 
Resistance only builds up into a problem when pests are repeatedly exposed to chemicals that have the same mode of action. If you need to use pesticides, alternate between different chemical families. For example if you used an organophosphate active ingredient last time, use a pyreththroid active ingredient next time. Changing the active ingredient that controls the pest in a different way, is mixing it up.
 
Mix it up!
