What insects eat fruit flies?
Keeping this in view, do ladybugs eat fruit flies?
There is nothing ladylike about a ladybug's appetite: an adult may eat up to 75 aphids per day! They also eat other harmful insects like fruit flies, thrips, and mites. Not all ladybugs are carnivorous, but the predatory ones are helpful to gardeners, because they do not damage crops while filling their bellies.
Considering this, do house centipedes eat fruit flies?
Your house centipede won't eat plants. Centipedes are carnivorous. I feed my house centipede flightless fruit flies that I bought at a reptile expo, little brown moths from my closet, and silverfish I found on the windowsill at work. You can probably get the fruit flies online.
Spoiled food can make people sick for a number of reasons, but not as a result of the fruit flies. While fruit flies themselves are not associated with any specific illness, there are some concerns about fruit flies carrying bacteria from one place to another and contaminating food with infectious microorganisms.
