Amaryllis are popular flowering bulbs which are forced indoors for their large, spectacular blooms during the winter months. The trumpet- shaped flowers can be as large as 8 to 10 inches across. Flower colors include red, pink, orange, salmon, white, and bicolors (mostly whites with pink or red flushes). Two to six flowers (the average is four) are produced atop an 18- to 30-inch-tall flower stalk.

The Asian lady beetle (Harmonia axyridis), is a common and widespread wintertime household pest across all of Iowa and most of the United States. Large numbers of these insects invade homes during the fall and remain active over the winter, especially in late winter when temperatures warm and days get longer. Ladybugs do not feed and cannot reproduce indoors; they have not multiplied indoors although it must seem that way to homeowners who have been inundated with them.
