Pests posing as guests A.K.A: Rose Chafer beetles

These varmints showed up about a month before harvest. In the last two weeks, they began to eat at the canopy of the vines. The preferred method of eradication was placing a pheromone trap to lure the beetles away from the vines. This was done within the last week before harvest as shipping for the trap took longer than expected.
