My DH is the maintenence supervisor at our local Public School. Unfortunatly we also have a huge cricket population explosion (millions) about every 3d or 4th year. In the past, the school would spray, and the students would be treated to the fumes and the scent of rotting crickets until the first good frost. (Trust me, in those high numbers, even live crickets DO have a scent)
New Texas regs require him to always use the least leathal solutions before resorting to pesticides. Through trial and error he’s discovered that if he sprays eucalyptus oil in the areas he wants them to vacate, they move away. He used it around the foundation and doorways and has cut the cricket problem drastically. He cuts the essential oil with a light (and cheap) carrier oil and uses a garden hand sprayer to apply the mix. When the scent fades, he reapplies. If you want more details, I’ll be happy to ask him specifics.
