Have Russian knapweed? Free insects for controlling Russian Knapweed are currently available through the Palisade Insectary. Supplies are limited and this is the last year they will be offered for free. The insect is a tiny wasp that does not sting or build nests and can help reduce the severity of the outbreak. This weed is pretty tenacious and is very hard to control without herbicide—it is damaging to our roads, agriculture and native ecosystems. Interested? Visit
