Fall is a great time of year, the weather is cooler, the trees are turning brilliant fall colors, and we can enjoy being outdoors. However, sometimes that enjoyment is smashed when insect invaders join our outdoor gatherings. The minute pirate bug is one that shows up this time of the year.
Minute pirate bugs are the tiny, black insects that seem to fall out of the trees in the fall and bite us. The bug, which is a true bug, is 1/8 inch in length and black with white and black wings. The appearance of this bug is very similar to a chinch bug. The wings have an “X” on them which is typical for insects that are true bugs.
Minute pirate bugs are present throughout the summer but they are out in fields, woodlands, and gardens. During the summer they are feeding on other insects. They are actually a beneficial insect. Pirate bugs are predatory insects that feed on many insects that cause harm to our plants, such as thrips, aphids, mites, and small caterpillars as well as the eggs of other insects.
Most people wouldn’t notice these pirate bugs if they didn’t land on us and bite us. Pirate bugs bite with a pain that doesn’t seem possible from such a tiny insect. However, some people may not notice the sting at all because the reaction to the bite can differ from no reaction at all to having the area swell up like a mosquito bite. But, in the fall, these insects move into the areas where people are more often outside and they begin to bite us. When they bite us, they insert their piercing-sucking mouthpart into our skin, which can be painful. However, the good thing is that they do NOT feed on blood, inject a venom or transmit diseases.
Because of the painful reaction that most of us receive from this pest, we want to do something to control them, however, control is not practical. Minute pirate bugs are a temporary pest, they are beneficial insects, and most of our solutions would not harm them so there is no reason to try to control them with an insecticide. Using a bug spray will not deter them either because they are not attracted to us by carbon dioxide like most other blood-feeding insects such as mosquitos. So, the best control for these pests would be to wear long pants and long-sleeved shirts and dark colored clothing or to wait patiently for cooler weather when they will no longer be a problem.
And just as a reminder, this is the time of the year when our insect invaders start to move into our homes. Many of the insects and other arthropods that we see every year are things like boxelder bugs, Asian multicolored ladybeetles, ground beetles, centipedes, millipedes, and spiders. All of these do not pose any physical harm to us, spiders can bite but it is rare and usually does not cause much harm. The best controls for these critters would be to use a home barrier spray, sticky traps and to vacuum them up as you see them. These insects and others are moving into our homes with the cooler temperatures to keep warm during the winter.
