MSU Urban IPM Alerts

With the first snow falling, it is hard to believe that it is only fall. While the sun will hopefully come out again, conifers are still getting ready for winter. You may see yellowing and/or browning of the inner needles, especially on pine trees. This is a natural process called "seasonal needle drop". No management is necessary. For more information, please check out the attached PDF file.

The elm seed bug is invading homes and coming indoors within the last several days.

It is the time of year when large, orange spiders are appearing on our front porches and decks. These are cat-face spiders.

Hobo spiders are entering buildings and homes. The male spiders start entering this time of year and females follow in September. They are common in the home until the end of November.

Montana has several home-invading weevils that come into our homes. They range from small, grey weevils (less than 3mm) to larger black beetles.
