The winter months can really drag out. You can’t go outside and garden and you are stuck indoors. It is at this time that you might start to notice some other critters coming into your home as well. There are a lot of home invading insects and arthropods that use our homes to stay warm through the winter.
One of my favorite non-insects from my childhood would be the roly-poly, which is officially called a pillbug. These arthropods are not harmful indoors and are often found in damp basements. They are also found in potting soil, so if you bring any outdoor plants inside for the winter, you may bring these inside with the plants. If pillbugs are found in your home, just pick them up to remove them from your home or vacuum them up.
Fruit flies are another problem in the winter months. They are tiny yellow flies with red eyes found around the kitchen. They are often found indoors attracted to fruits, vegetables, beer, sodas, and fermenting things in our garbage. These fruit flies are a real nuisance as they fly around us and our food in our homes. For management of fruit flies, it is best to eliminate their breeding locations and food sources. Throw out all fruits and vegetables past their prime for eating and make sure to rinse out all beer and soda cans and bottles before throwing them away. It might also be helpful to just keep your trash in the garage or other location near the house to avoid problems indoors. For those left in your home, you can make a fruit fly trap easily and cheaply. Take an empty container such as a jar or yogurt container and fill the container 1/4 of the way full with apple cider vinegar to attract the fruit flies. Put a few drops of dish soap in the vinegar to make the flies sink as they land on the vinegar and cover the container with a layer of plastic with a few holes poked in with a toothpick to allow the fruit flies in. This will bring the fruit flies in to die in the vinegar which attracts them to the trap in the first place.
Another aggravating insect pest indoors in the winter would be the fungus gnat. Fruit flies and fungus gnats are often confused, but opposed to the bright colors of a fruit fly, fungus gnats are tiny black flies. Fungus gnats often get into our homes in houseplants or potting soils used indoors. They are not damaging flies, but they can be a real nuisance indoors. To rid a home of fungus gnats, there are many options. Try repotting the plants and allowing the soil to dry out more between waterings. You can also place a yellow sticky card next to the plants that will attract the gnats to kill them in the sticky glue on the card. Finally, you can treat the soil with insecticides labeled for use on indoor houseplants or use a mixture of 1 part bleach to 10 parts water and run that through the soil to kill any maggots left in the soil.
Soon we may begin to notice ants in the home or the winged reproductive stages of ants which are common in the spring months. If temperatures warm up for a few days at a time, some ants may even become active in the late winter months. Ants in the home are mostly a nuisance pest, but can sometimes be quite difficult to control. Liquid ant baits or bait stations are the best for control of these pests. Also, be sure to reduce overgrown landscaping outside the home around where the ants are coming in and use barrier insect sprays to reduce their movement into the home.
