Microscopic wasps offer solution for moth infestations in Australia

Cleaning out a wardrobe, Megan Gallagher discovered moths and their larvae in her home. She realized these pests were everywhere and sought solutions with her friends Maree Whittaker and Marion Thomson. They explored various options like mothballs and sticky traps but found most unsatisfactory or unsafe. Instead of chemicals, Ms. Gallagher researched biological methods and found a Queensland company that sells microscopic wasps to combat moths. These tiny wasps specifically target moth eggs, laying their eggs inside them. As they hatch, they consume the moth eggs from within. Dan Papacek, an entomologist and founder of the company, explained how these wasps are beneficial in agriculture and can reduce the need for harmful pesticides. He emphasized the wasps' narrow focus, which helps prevent them from becoming a problem themselves. The wasps are shipped in large quantities, and Ms. Gallagher and her friends ordered several containers. They released the wasps in various rooms and quickly began to see positive results. After a few months, she noted a significant drop in moth sightings. Although effective, Mr. Papacek cautioned that using wasps is only part of a broader pest control approach. Regular checks and good storage practices also help to prevent infestations. Following their experiment, Ms. Gallagher and her friends plan to introduce ladybirds into their gardens to control aphid populations.
