As the days grow colder during fall, these fall pest invaders begin to appear on the walls and windows of your home that seek warmth and shelter. As temperature drops various pests move indoors. These are the common fall invaders:

Ladybug or Asian Lady Beetle

Like many animals and bugs, ladybugs come indoors to escape the cold weather, hibernate, and potentially lay eggs. The most common places you might find them are in the doorway, window, or even inside the house. They tend to gather in large numbers, often around windows and light sources. Ladybugs are harmless and they don’t bite. Some people experience allergic reactions like sneezing and skin irritation when in close contact with ladybugs.

Stink Bug

The brown marmorated stink bug or Halyomorpha halys named for its smelly odor, especially when stepped on. When a stink bug feels threatened, it releases a pungent substance from special glands, repelling nearly any predator that has a sense of smell. Similar to Asian lady beetles, Stink bugs will move into homes in the fall and winter. You can find them in your house, because stink bugs require a warm environment to stay active and alive.


When fall arrives, spiders become more active, many of them are searching for mates, weaving their web indoors and laying eggs. Spiders seek warmth, so when the cold winds arrive they look for a shelter inside your home.

Cluster Flies

Cluster flies are large black coloured flies, they are very much similar to a house fly. Cluster flies are an indoor nuisance, but they are not breeding in your walls, and unlike horseflies, they do not bite.
