Autumn is the time of year for pumpkin spice, cozy sweaters and cooler temperatures throughout much of the United States. Dropping temperatures and shorter days also signal that winter is coming to insects. Fall invading insects will begin searching for a place to hunker down indoors to survive freezing winter temperatures.
What are some examples of common fall invaders?
Insects like boxelder bugs and lady beetles (also called “ladybird beetles” or “lady bugs”) can become a problem for homeowners. Additional common fall invaders include brown marmorated stink bugs, cluster flies and spiders.
What is the target temperature for an overwintering pest?
Their ideal overwintering temperature is between 40 to 50°F - which just happens to be the temperature in the wall voids of a house. It’s common to see them on the sunny southern or western sides of buildings in fall months, looking for a way into wall voids.
Is a vacuum a good option for occasional fall invaders?
Yes! A vacuum is an excellent option if fall invaders have already moved indoors. However, be aware that vacuuming stink bugs will cause smell and a vacuum with a HEPA filter should be used. Lady bugs can also be problematic during removal because they can stain surfaces, like walls, if squished. So, be careful when vacuuming to remove lady bugs to limit squishing and staining.
What CSI product is a good option for fall invaders?
The best defense against fall invaders is to keep them out in the first place. These insects can fit into a crack the thickness of a credit card, so an opening does not have to be large for pest entry. Bifen I/T is an excellent choice outdoors to help prevent the invasion of fall invaders. Apply Bifen I/T around the structure where pests are observed or potential entry points, such as foundations, windows, doors, plumbing penetrations etc.
