As the weather warms up, flies and other insects will be back to challenge our livestock. If you have experienced decreased effectiveness of your pest management strategies over time, you may want to take advantage of the opportunity to hear from K-State Research & Extension livestock entomologist, Dr Cassandra Olds. You can access her virtual presentation entitled ‘How the creepies affect the crawlies: sustainable endo and ectoparasite control in livestock’ on the Rawlins County Extension YouTube Channel at https://www.youtube.com/watch?v=dl2pGCqO5u0 . She discusses problems with resistance to endectocides and management strategies to reduce the rate of resistance development.
