Hort Update- Seasonal Information for the Green Industry
This viewer thinks they had wireworms invading last fall. They're wondering whether there's anything they can do to keep the bugs from invading the house next fall.
They are probably referring to millipedes; little elongated, dark colored insects that have many legs and coil up in a circle when they die. The key to preventing a problem next fall would be exclusion, since they come indoors seeking overwintering sites. They're very adept at finding openings around plumbing or electrical outlets or around the doorways as entry points. So thoroughly seal all those cracks and crevices. Then buy some sticky traps in the fall, and place them in areas where you have had problems in the past. Sticky traps will collect many insects- wood roaches, crickets, roly-polies- and the millipedes. For serious problems, you can use a foundation spray of bifenthrin or permethrin, two or three feet up the sides of the foundation. That will keep them from staying in that area. Generally, sealing and putting some sticky traps out, that's what I do.
