As we wind down the year, creatures stirring in our home are less obvious. Mice seem more abundant in fall. A mouse was caught in a trap yesterday and a short-tailed shrew was caught in another. I am dismayed to kill a shrew because they are nature’s living mouse trap. A drug carried in their saliva causes mice to become uncoordinated when bitten. It becomes easier for the shrew to kill the mouse. Shrews eat more than their weight daily. A mouse is a good day’s meal. I take comfort in the idea that shrews control our mice population (I hope).
Some would think nature niches stop at our door step but that is not the case. Wildlife inhabit our homes whether we want them or not. Humans are not separated from nature at any time. Air infiltrates our homes. Warmth arrives from furnaces to maintain our tropical environment. House plants filter air, remove chemicals and purify living space. Be thankful for air leaks and house plants.
We have become better at sealing air leaks, but home air quality studies show air in modern homes are not as healthy as in poorly insulated homes. We insulate well and have many house plants to purify air. I encourage each of us to have many house plants. It is most important in winter. Bring nature into the house.
Other creatures live in our homes. During the summer we notice more insects. Flies become a nuisance. Screens work well but an open door allows them to sneak in unnoticed. They lay eggs on hidden dead mice and within a few days reduce the mouse to fly flesh.
A naturalist friend is a spider specialist and tells me we are never more than three feet from a spider in the house. Spiders eliminate many insects. Cherish spiders in the house. Most are actually smaller than a mosquito but we notice the larger ones. Many do not build webs but hunt their prey. The lack of web building helps them stay hidden while they secretly do important work. Save money by letting spiders do pest control for free instead of hiring a company to treat your home with chemicals.
That is not always acceptable. When we bought our house, we had a termite problem and needed to hire a company to save the house from serious damage. Back then dangerous chemicals were used and I wonder if that could be a source of my cancer. Doctors have no common links among people with multiple myeloma. The cancer cause remains a mystery.
Termite life history studies have revealed ways to get them to carry hormone material to the termite nest that interferes with reproduction without putting dangerous chemicals in the home and it only affects termites. The absence of termites opened living space for carpenter ants that threatened the structural integrity of the home. We needed to call a pest management company. Chemicals were used around the perimeter of the house. I do not want that, but find it necessary. I inquired and requested use of the safest chemicals.
Many insects live with us and we get along fine. Very few cause health, safety, or damage to people or the homes. Some can be a nuisance. The European “ladybugs” have become abundant and enter home siding to hibernate by the thousands. Many get into houses. Too many around is disturbing and unlike native ladybugs, they will bite. Some Leaf-footed bugs enter the house. I just pick them up and release them outside. Earwigs scurry in damp areas. They do not enter ears. Crickets are often only noticed when they serenade during dark hours when we choose to sleep.
Many species of flies enter the house. I recently removed the kitchen ceiling light cover to empty dead fly bodies that accumulated during warmer weather. Species of small micro moths are present. In the bathroom, I saw small moths in the bathtub. A closer look demonstrated only two wings and proved them to be a fly named moth fly. It feeds on sludge in the drain for free—less drain cleaner needed. The list of creatures that share our homes is long. We mostly get along well with household creatures except for a few that will eat our home from under and around us. Find a balance with minimal creature control.
