With more than 150 plants and a spider-mite problem, Reddit user u/VeganMisandry announced a different kind of delivery: 100 beetles. The container in their photograph was labeled Stethorus punctillum, sold as spider-mite destroyers.
In the r/houseplants post, the grower said they had tried predatory mites before. Their excitement about the beetles centered on one difference:
“these guys can FLY!!”

Specialists, not interchangeable ladybugs
Cornell’s biological-control guide identifies S. punctillum as a small lady beetle whose adults and larvae prey on mites. The species matters. Buying a different insect because it is also called a ladybug is not the same control strategy.
The photograph documents the product the owner obtained. It does not establish how many pests were removed or whether the release ended the infestation. The thread’s jokes about the next animal to release should not be read as treatment advice.
Identify the pest before ordering its predator
University of Minnesota guidance describes spider-mite damage and inspection. Look at leaf undersides and fine webbing; a hand lens can help. Pale speckling has several possible causes, so do not order living controls on a guess.
Make a map of affected plants. Record where you see live mites, where you only see old damage and which neighboring plants need checking. That gives you a baseline for assessing treatment.
Ask about conditions and previous sprays
Before ordering, tell the supplier the pest, the indoor setting and any products recently used on the plants. Ask about suitable conditions, release timing and compatibility. Residues on foliage may conflict with a biological-control plan.
Inspect the affected specimens and review our Alocasia pest guide or Monstera troubleshooting guide as appropriate. Species-specific care helps separate pest damage from stress in the root environment.
Keep inspecting leaves and count live pests over time. The scale of this grower’s collection makes the story memorable, but a hundred insects is not a universal dose for another apartment.
