The cRc states that there has been a significant increase in insect infestation of blueberries. Based on that information, they recommend that the following procedure be followed to all fresh blueberries until October 31, 2012…
1.) Prepare a quart-sized bowl of soapy water per pint of blueberries
2.) Soak and agitate the blueberries in the soapy water for 20-30 seconds.
3.) Rinse the blueberries under running water.
An exception to this method includes organic blueberries, which should be washed and checked using the thrip-cloth method. Additionally, U-pick blueberries should be avoided as they are often infested with scale insects and other bugs. One should only use them if they were first checked for scales and other insects using a thrip cloth.
