I released minute pirate bugs 6 days ago, and I don't want to jinx it, but I haven't seen a thrip since. I only noticed I had them on my petunias and a couple lighter colored collarettes but I'm sure there were some elsewhere. I have an issue with tarnished plant bugs and the minute pirate bugs are supposed to eat all juvenile stages of those. Since releasing them, I haven't seen an adult either! They also eat spider mites. It's probably too early to really tell, but I'm definitely encouraged. After Japanese beetle season is over, my main pests are spider mites, thrips and TPBs. If the pirate bugs work, I may not have to spray anything except fertilizer and fungicides! 🥳🥳🥳
