Now that Fall is officially here, the weather is starting to cool down and we can venture outdoors more. Activities such as Hiking, harvesting, hunting, football, and just enjoying the cooler weather on your patio in the evening are all pleasant outdoor activities this time of the year. However, when we venture outdoors, our plan is never to be the menu for all the pesky insects outdoors.
Mosquitoes are out in full force right now. After the rains we have seen over the past couple of weeks, their population has exploded. Mosquitoes can transmit many diseases, so it is best to protect yourself when you are outdoors. Use Insect repellent and wear long sleeves and long pants or permethrin-treated clothing when outdoors between dusk and dawn when mosquitoes are most prevalent.
As far as chemical control, Mosquito Dunks contain the active ingredient bacterium, Bacillus thurengiensis israelensis (Bti), which is toxic to mosquito larvae when consumed, but non-toxic to humans, pets, pollinators, fish, and other wildlife. They are sold in hardware stores, and will dissolve in standing water such as water troughs, fishponds, rain barrels, and birdbaths. They are effective immediately and can last for a month. For homeowners, it is not recommend to use foggers or adulticide treatments. These treatments are not effective for more than a couple of days and should only be used a few days ahead of a large outdoor get-together if absolutely necessary. At this point, it would be best to just wait for a frost to kill off the majority of our mosquitoes. Our average first frost date is the end of September to the beginning of October, so one should be here soon.
Minute Pirate Bugs
Minute pirate bugs are also a nuisance right now as well. Minute pirate bugs are the tiny, black insects that seem to fall out of the trees and bite us during the fall months. The bug, which is a true bug, is 1/8 inch in length black insect 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, making them a beneficial insect. 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. Some people may react differently and swell up from the bite, but most people just have the initial pain with the bite. Minute Pirate bugs do NOT feed on blood, inject a venom or transmit diseases. Control is not practical for them as they will also die with our first frost. Insect repellents do not deter them, so it is best just to wear long pants and a long-sleeved shirt to reduce areas for them to bite us.
Ticks are also still a problem this late into the season. Ticks are common in wooded areas or in tall grass. If outdoors in areas where ticks are commonly found, wear light-colored, long-sleeved shirts and long pants and closed toe shoes to reduce exposed areas where ticks can attach to your skin. Also, use insect repellents any time you are outdoors, the repellents with DEET have the highest efficacy. One tick I have seen recently is the immature form of the Lonestar Tick. This immature form is very tiny in size and would be easily missed by a quick visual inspection. This tick can spread diseases if left to feed on you long-term, so be sure to protect yourself prior to going outdoors and check yourself when you come indoors.
