Question: What are the little brown worms in our basement that curl up and get crunchy when dead? We live in south central Iowa and have had these worms in our basement practically year-round. Is there a way to get rid of them?
ANSWER: Probably what you have is the common millipede (Class: Diplopoda). They are characterized by the numerous legs on each side of the body, thus the name ”thousand legger.” These animals are common household invaders, especially from spring to fall.
They live outdoors in moist and decaying organic material (dead leaves, flower garden mulch, even the thatch layer in turfgrass), and usually go unnoticed at these locations. Sometimes millipede populations increase rapidly, or their environment gets too wet, and they start to migrate to get away from these conditions. They usually move to the sides of houses (where it may be warmer and drier). They sometimes come inside under door thresholds and around windows at ground level.
The best control is to remove as much of the moist mulch around doors and away from the foundation as possible (make a 6″ to 12″ gap between mulch and house). This reduces their breeding sites and the favorable areas for them. Make certain the door thresholds are well sealed. These animals don’t reproduce in houses; in fact they die soon after they enter because the environment is too dry for them.

Question: I have some bugs that look like worms that are about 1/2 inch long. I just wanted to know, what are they?
Question: I recently moved in to the basement of a friend’s house (the house is around 30 years old). However, prior to the move, I had discovered these gray wormlike bugs, curled up like a coil, dead, all along the baseboards/trim on the floor. They are grayish/silverish in color, about the width of a toothpick, maybe half an inch in length. I vacuumed them up and figured they should be all dead. Unfortunately, this morning I found one alive “crawling” on the floor. It moved like a centipede, not sure if it had legs or not, but it didn’t appear to move like a worm. When killed, it excreted a bright yellow substance. This is the first one I’ve found alive … do you know what this is? How can it be treated? What should I do to get rid of them? Thank you.

Question: We have thousands of inch-long worms on the east side of our garage. Contractor said it was on a worm bed. The worms have a hard shell; gas does not kill them. They are black, and I don’t know if they turn into another insect.
