A million little critters
I noticed these "patches" of pinkish little things over the surface of our swim pool the middle of this February. I have lived in this house for over 20 years…never seen this before. The location is on the Central coast of California, San Luis Obispo. The size of the creatures are about 1 to 1.5 mm Any thoughts??
These are Springtails, minute insects that are found in large aggregations. They are often associated with swimming pools. Perhaps the drought this year has led them to your pool if they have never congregated there before. Springtails need moisture to survive, and they flourish under the proper conditions.
