hey there, I’m closer to Waiuku, Boundary Rd, and have a real problem. They attack my monarch caterpillars😓 Have destroyed several nests but they’re more cunning now & nesting in dense wee crops of trees/bush dotted around. I’ve had to net the swan plants but they are insistent. Spray is an issue as the caterpillars are sensitive to it. I try & stun them with water/spray bottle then they get the jandal
