Where Do Bugs Come From?
Your warm home may be irresistible to bugs seeking shelter from the cold. As we lose the heat of summer, bugs actively seek warmer places. Once a few insects find good shelter, they give off a chemical signal inviting others to join them. Any crack or crevice in the exterior of your home, large enough for a bug to slip through is an open invitation. They don’t do structural damage to your home. They are just waiting out winter.
If you are asking how they came to exist, it is simple. They were created by our Maker: Genesis 1:24-25, And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so. And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good.
