Do they look like any of these? If so they are good critters.
Beneficial BugsDescription
Amblyseius Californicus A predator mite that feeds on the hatching eggs of thrips and the larval stages. They naturally occur at a ratio of 2 females to every male and each female can lay from 1 to 4 eggs a day.These predator mites work best at mild temperatures around 70 degrees fahrenheit and are somewhat resistant to pesticides. For best results they are applied at 10 predator mites per square foot of garden.
Amblyseius Cucumeris Beneficial bugs that are pretty much the same as Amblyseius Californicus except that spider mites are the choice food. These female mites will actively seek out spider mites and suck them dry.
Chrysoperla Carnea Otherwise known as Green Lacewings. These beneficial bugs are actually beautiful to look at and this picture does not do it justice. They are an all-around voracious predator feeding on spider mites, aphids, thrips, whiteflies, scale and mealybugs and can eat up to 60 aphids an hour.Shipped as eggs that are ready to hatch, lacewings are best applied at a rate of 10 eggs per square foot. When received they can be stored in the refrigerator for a short time as long as eggs have not hatched; if they have apply immediately or the cannibilistic larvae will destroy each other.
Phytoseiulus Persimilis Another voracious predator mite that feeds on all stages of thrips and spider mites (and if food is not available they may feed on each other). They live about 50 days and in that time a female can lay up to 60 eggs that hatch in 2 to 3 days. An adult can eat up to 20 prey per day
