Hornets are looking for three things: a sheltered nesting site, a food source, and access to building materials. Your home's eaves, soffits, and siding offer all three.
They do—and a mouse infestation produces a distinct stale, musky odor that comes from a combination of urine, droppings, and nesting material. The stronger the smell, the more established the population likely is.
Mosquitoes spend most of the day resting in cool, shaded, humid areas. That includes under leaves, inside shrubs, beneath decks, and along fence lines where they're protected from sun and wind.
Ants send scouts to find food and water sources, and when a scout finds one in your home, it lays a chemical trail that brings the rest of the colony right behind it.
