Why are my caterpillars turning red?Updated 9 months ago

If your caterpillars turn red and begin to disintegrate, they have been infected with the bacteria, Seratia Marcescens.

 

This bacterium occurs if condensation has been allowed to form in the cup. Please be sure to always keep your Cup of Caterpillars away from windows and out of direct sunlight.  Sunlight will cause the inside of the cup to heat up and form condensation.

 

Please contact us with some photos if this happens to your caterpillars.
