Everyone loves fall—the leaves are changing, football season has commenced, and the weather is starting to cool down. The threat of mosquito bites is fading away, and one would think that bugs in the house should be less of a problem. But there are many pests that still linger, looking for a way into your home through small, unnoticeable cracks and crevices, hoping to find a safe, warm place to spend the winter. We’ve compiled a list of some common house bugs and pests in Maryland that may be lurking too close for comfort this season:


The truth about ants is this: if there is food, they will come. Regardless of the time of year, it’s essential to keep your home (especially the kitchen) free of food crumbs and dirty dishes to avoid an unsettling infestation. Learn more about the various types of ants in our area.


Rodents, such as mice and rats, commonly seek shelter from the cold weather in basements and attics. While that is unpleasant enough, it’s also dangerous, as rodents tend to chew on anything they can find, posing a threat to electrical wires and other elements inside your home.


Cockroaches are a constant worry for homeowners. These pests prefer warm areas that are close to food and water, which is why they are commonly found near kitchens, bathrooms, and trashcans. Not only can cockroaches carry several different types of diseases, but they can also trigger allergic reactions and asthma attacks, especially in children.

Yellow Jackets

Yellow Jackets build their homes in the ground or holes in walls and buildings. They can work their way into your living space if you’re not careful. If you see any signs of yellow jackets in your home—especially after the first frost—this means you most likely have a nest in one of the walls of your home.

Boxelder Bugs

Boxelder Bugs are very commonly found in areas containing boxelder, ash, or oak trees. They cannot survive in the winter, so during this time of year, they gather together and attempt to find shelter—sometimes finding their way indoors.


Although they can be poisonous to smaller animals and insects, ladybugs are generally harmless to humans. During the fall and winter months, your home provides warm shelter making it the perfect safe haven. While a single ladybug does not pose a huge issue, they can secrete a powerful pheromone, attracting hundreds of ladybugs, inviting them to spend the winter in your home. Additionally, when threatened, ladybugs can secrete a yellow liquid that is toxic to small animals if ingested. This liquid can also stain fabrics in your home.

Stink Bugs

If you’ve ever squished one by accident, you know how they got their name! Stink bugs are surprisingly sneaky and are capable of leaving an invisible scent trail of pheromones, similarly to ladybugs, that leads other stink bugs to shelter.
