Occasionally, particularly in hot weather, you may find few small moths in a bag of birdseed. Known as “Meal Moths”, they are common in all types of grain and cereal products. When you try to swat them, they just seem to evaporate into nothing.
Adult moths lay their eggs on the seed crop before it is harvested but, since the seed is for consumption, farmers can not spray the crop with insecticide to kill the eggs. So the eggs remain attached to the seed. When the weather warms, the eggs hatch resulting is some moths. Fortunately these moths are not the type of moth that attacks your woolens. And birds love to eat them.
But no one wants to have moths in your house. If they are a problem for you we have moth traps that do a wonderful of getting rid of the moths.
The seed that attracts the widest variety of birds, and so the best choice to offer, is sunflower. The worst choice is an inexpensive mixture, especially if it contains red millet, oats, and other “fillers” that most birds in most areas spurn. Wasted seed provides a breeding ground for bacteria and mold that can harm birds. –
