Fall is my favorite season of the year. The weather is much more enjoyable, the trees turn fantastic colors, and football begins again. With all the fun of fall, however, comes the not so enjoyable entry of insects into our homes.
Most people see the same insect pests in their homes each year. The majority of household pests that we tend to see most often in the fall invading our homes for warmth and food are boxelder bugs, Asian multicolored ladybeetles, and spiders. None of these really warrant any control by a pesticide, they are fairly easy to control and do not do any real damage to your homes or to you.
Boxelder bugs, or Democrats as some people call them, are a common nuisance pest to enter homes in the fall and they are often seen leaving the home in the spring. These are the insects that are black with a reddish-orange X on their backs. They are a type of a true bug that is found feeding on many trees but they prefer boxelders, ash, and maples.
Multicolored Asian lady beetles are a nuisance pest as well, that we often see in the fall. These are the ladybugs that we find in our homes in the fall. These ladybugs can bite and it can cause pain, but they don’t cause any medical issues. The biggest problem with these lady beetles is that they get in the house and are found all over your home. They are just trying to find a place to hide out for the winter.
Spiders are common in our homes throughout the year, but tend to be found more during the fall and winter. The most common spider that people bring into my office to be identified is the wolf spider. Wolf spiders include one of the largest species of spiders found in Nebraska. They are quite hairy and often times will have 2 white or lighter brown colored stripes down the back of the spider. There are some wolf spiders that can be the size of a half dollar or more, legs and all. These spiders are not poisonous, but they can bite. Most often, a wolf spider will not bite us, but if they do the reaction is mild.
Brown recluse spiders are becoming more common in southeastern Nebraska. These spiders are about the size of a quarter, legs and all. They are a brown color with a darker brown fiddle shape on their back. They can cause a bad reaction in some people, not all people are as sensitive to the bites as others. If you have brown recluse spiders in your home or office, just take the time to look around things that have been stored before you move them. Most of the time, if a person gets bit it is because they accidentally trap the spider between themselves and either an article of clothing or a box. The best way to ensure you do not get bitten is to shake out items when you take them out of storage and watch where you put your hands when you pull boxes out of storage.
Household invading insects and spiders, generally, will not cause any damage to your homes or yourself. The only problems with these insects being in your homes is that they can come in swarms and they have an “ick” factor as most people do not enjoy insects, especially in their homes. The best control for these insects include:
- Sticky traps around the home
- Step-on or smash any you see
- Vacuum or flush any found
- Seal up all cracks and crevices on your home and door and window screens
- Indoor/Outdoor barrier sprays can help reduce the population of some home invading insects and spiders
- Do NOT spray a population of insects found in a wall void, this can lead to a secondary insect population that comes in your home to help decompose those dead insects left in the wall void
