There are two defining characteristics of powderpost beetle infestations. First, small piles of the powdery sawdust will appear and reappear after cleaning, under, around or on top of infested furniture or lumber. Second, numerous small, round holes (1/16 inch diameter) appear on the wood surface. Only when the wood is broken open do you find the criss-crossing, powder-filled tunnels inside the wood.
Forcing flower bulbs indoors is an excellent way to brighten the cold, gray days of winter. Tulips, daffodils, hyacinths, crocuses, and other spring-flowering bulbs can be forced indoors. Paperwhite narcissus can also be forced indoors. Paperwhite narcissus are easy to force. Unlike tulips, daffodils, hyacinths, and crocuses, paperwhite narcissus don't require a cold storage period to flower.
