The dried fruit beetle belongs to the family Nitidulidae, which contains the sap beetle. It is the most important pest species of this group. These beetles are strong fliers and constantly search for ripe or fermenting fruit. More than 1,000 tiny white eggs may be deposited by the female on ripening fruit on trees or fruit on trays drying in the open. Infestations, therefore, often begins prior to the fruit being processed or stored in packing sheds. Another source of dried fruit beetles and other sap beetles are refuse dumps where fruit by-products are disposed. Infestations never occur on whole sound fruits. Fruit is attacked before it is completely dry and usually, only cracked or fermenting fruit is infested. The larvae are white to amber in colour and grow to about 0.25 inch in length. Development to the pupal stage takes two to four weeks during which the larvae undergo several moults. Each moult results in a cast skin left behind and, together with faecal droppings, infested fruit can be rendered unpalatable by just a few larvae. The life cycle can be completed in a minimum of 15 days during hot weather, but may take months during colder months. During their activities, dried fruit beetles may carry yeast cells, fungi and bacteria into the fruit causing it to sour and spoil.


The dried fruit beetle is found worldwide, especially in regions where fruits are grown, processed and stored. These beetles attack both fresh, ripened fruit and dried fruits prior to storage and packaging. This beetle is especially fond of figs and dates and is a common pest of raisins.

Tips for Control

The control of any stored product pest involves many steps, primary of which is discovery of infested food items or other sources of infestation (e.g., food spillage accumulation). This beetle will only be associated with moist, fermenting fruits, so it is an uncommon pest in homes.

Consider the following to prevent an infestation:

 Discard infested foods in outdoor trash. Infested decorations (flowers, wreaths, etc.) should also be discarded.
 Freeze suspect foods at zero degrees Fahrenheit for six days.
 Refrigerate all fruit products and store dried fruit products in a glass or plastic container with a tight lid.
