Permitted Activities

Outlined below are responses to some questions which have arisen concerning what activities are permitted with the indoor (general pest) and outdoor (custom ground) certificates.

  1. Generally, any spraying indoors belongs with the indoor certificate.
  2. Spraying outdoors with an indoor certificate would be permitted in situations such as:
    1. For termite or rat control if the certificate holder holds a termite or rodent license.
    2. For control of indoor pests that enter from the outside, such as clover mites or earwigs, on the outside foundation of the house and on grass in the immediate vicinity of the foundation.
    3. For wasps if the nest is in the immediate vicinity of the house.
  3. Spraying outdoors with an indoor certificate would not be permitted for insects that are only casually a pest indoors. For example:
    1. if a heavy flight of aphids is bothersome to people on a porch, a holder of an indoor certificate would not be allowed to spray the plants in the yard from which the aphids came; or
    2. if wood roaches are coming to lights on a porch, a holder of an indoor certificate  would not be allowed to treat outside areas.
  4. An outdoor certificate holder could also:
    1. treat for clover mites or earwigs on the outside foundation of the house, but not within the house;
    2. treat for ticks outdoors;
    3. manage Canada geese on the lawn using general use repellents; and 
    4. mange deer with repellents.
  5. Chlorpyrifos (Dursban) has been be phased out. December 31, 2001 was the last sale date of the product. However, any existing stocks can be used up after that date.
  6. Diazinon has also be phased out. The last sale date of Diazinon used for indoor was December 31, 2002 and the last sale date of Diazinon for outdoors use was December 31, 2003. Syngenta began a product recovery program in 2004 for Diazinon.
