rodenticides. A percentage of them were unintentionally using inside-approved products outside or not using bait stations for their outside use.


Most of the farmers interviewed used anticoagulant rodenticides to prevent property damage, or for food safety reasons.


Only about a quarter of them used professional pest control operators to run their programs. A number of berry growers were documented using a


product that was not approved for outdoor use, but about half the farmers interviewed were very concerned about harming non-target wildlife and pets.


In conclusion, she noted that predators scavenging on dead rodents are consistently found with residues of anti- coagulant rodenticides in their systems.


If people disposed of dead rodents found outside so they were inaccessible to predators, the unintentional poisoning of those predators would decrease, she noted. Hindmarch recommended the use of Integrated Pest Management principles, including a focus on encouragement of raptors such as owls for rodent control, instead of using pesticides, which can harm the very predators which could solve the problem. Examples of nest box installations and habitat enhancement for barn owls are available on the web at: barnowlsbc.ca


Here’s a link to the Pesticide Regulatory Agency list of where rodenticides are allowed to be applied depending on the active ingredient: http://sgspestmanagement.ca/wp- content/uploads/2013/03/PMRA-New-Restriction- Rodenticides-eng.pdf
