SPRAYING FOR SPRUCE BUDWORM
 
Please be aware that the spray Safers btk (bacillus thuringienis kurstaki) is available in small quantities at Canadian Tire and Art Knapps.  100ml makes 30 litres of spray and costs about $12. 
 
You should be able to also buy a wand sprayer that would mix and spray the bacillus on to understory small trees and as high as you can get up, on larger trees. 
 
Early morning is best for spraying when the air movement is little.  Please read and follow the directions on the package/container.
