Indoor Vs Outdoor Cockroaches

Different types of cockroaches can be found inside and outside. There are even some that can be found both inside and outside. The term building is often used interchangeably with indoor space or residential building. It can also be synonymous with the indoor place like homes and offices as well as the landscaped portion like a garden, backyard and patio which are considered as outdoor area.

Indoor Vs Outdoor Cockroaches

Many cockroaches prefer to live outside than in homes. Regardless of the species, cockroaches live in warm places that offer protection from predators and access to food and water. Many cockroaches also dislike artificial light, so outdoor environments replicate natural conditions and enable roaches to hide away until it gets dark.

Cockroaches also tend to congregate together in large colonies, even when they’re outside. They do this by using several communication methods, such as:

• Pheromones: According to the Chemistry of Pheromones and Other Sociochemicals, cockroaches use pheromones to command one another to do things.
• Aggregation Pheromones: These are a type of chemical made up of poop, fatty acids, and skin that cockroaches use to get each other to assemble in one specific area.
• Stridulation: Cockroaches rub their wings and legs together to create friction, making a soft sound that other cockroaches can hear. They also make a soft chirp by opening and closing holes in their exoskeleton.

When cockroaches are outside, they live amongst or underneath materials that provide them with the protection and warmth they need to survive. They rarely live anywhere out in the open, as this would leave them vulnerable to predators. Nevertheless, there are many places they will live outside, including:

Tree Trunks

Rotting tree trunks are a great place for cockroaches to live. Not only are they warm and damp, but the decaying wood provides them with the food and sustenance they need.

Shrubs and Flowerbeds

Cockroaches also live in shrubs and flowerbeds. They’re not attracted to flowers and plants but the warmth, moisture, and shelter that soil provides. However, some roaches eat decaying plants and leaves, so living near shrubs and flowerbeds sometimes provides an essential source of food and water, enabling cockroaches to thrive. You can get rid of cockroaches in shrubs and flowerbeds with:

• Diatomaceous earth
• Baking soda traps
• Sticky traps
• Submerging the roaches in water

Leaf and Wood Piles

Leaf and woodpiles are both suitable homes for cockroaches to live in. Oriental cockroaches, in particular, enjoy living amongst leaves, wood, and mulch where it’s moist and dark. American cockroaches are also known to live in woodpiles. If you keep leaves and wood close to the boundaries of your home, there’s a chance cockroaches could move into your home to find warmth when it starts to get cold.

Cockroaches also enjoy living amongst bark and pine straw mulch. Both materials are lightweight, enabling roaches to burrow deep. Decaying bark mulch is also a good source of food and energy.

Compost Piles

As described by Biotropica, cockroaches are detritivore-herbivore insects. This means they eat many different kinds of decaying food – many of which are placed in compost piles, such as:

• Meat
• Decaying fruit and veg
• Food scraps, such as avocado skins and potato peel and
• Grass clippings and leaves
• Newspaper

These things are some of a cockroach’s favorite foods, and living in a compost pile gives them plenty to feed off. While you might want to keep cockroaches out of your compost pile, they can benefit the decomposition process. Not only do cockroaches decompose when they die, but they break down trash as they eat it, turning it into reusable matter.

Garbage

Garbage cans contain many of the same decaying foods as compost piles, including grease spills, rotting fruits and vegetables, and meat carcasses. Alongside sugary, starchy foods, these are some of a cockroach’s favorite things to eat.

Cockroaches can also chew through flimsy plastic bin bags to get to the food due to their strong mandibles (jaws). This means garbage cans are breeding grounds for cockroaches and their nymphs.

Sewers and Drains

Cockroaches, especially Oriental and American cockroaches, live in underground drains and sewer systems. There’s plenty of moisture in drains and sewers, and cockroaches remain safe from predators when inside them. Pipes are also insulating, keeping cockroaches protected from freezing temperatures in winter and hot temperatures in summer.

Not only that, but drains and sewers give cockroaches access to indoor environments should they wish to leave the outdoors. This is why some cockroaches end up in bathrooms.

Should I Be Worried If I See A Cockroach Outside My House?

Before you worry that you have cockroaches in your house, you should first identify the species. If you see a German cockroach in your yard, there’s a chance that you have an infestation inside the home. That’s because, as we’ve mentioned, German cockroaches are common house invaders that can’t live outside in the cold.

Other cockroach species are less likely to have gotten inside your home as they’re happier to live outside. Cockroaches have no reason to move inside as long as there’s warmth, shelter, food, and water outside.

The risk of a home invasion increases when there are no resources outdoors but plenty inside your home. When this happens, cockroaches are forced to search elsewhere for the things they need. If you’re concerned about a cockroach you’ve seen outside, look for signs of an infestation. These include:

• Musty odor
• Small droppings that look like coffee granules
• Shed exoskeletons
• Brown smears
• Bite marks and damage to furniture
• Cockroaches themselves

These are tell-tale signs that cockroaches have moved into your home from the yard. As a result, you’ll need to act fast to remove them and protect your belongings. If you don’t notice any of these things, it’s likely the cockroaches you saw are confined to the yard for the time being. So, take measures to prevent them from migrating inside.

Indoor Vs Outdoor Cockroaches

Indoor cockroaches prefer to live in warm and moist environments. They are commonly found in drains, sewers and basements.

Outdoor cockroaches prefer to live in warm, humid and temperate weather conditions. They are commonly found on the ground under leaves or debris, or in grasses and gardens.

Cockroaches are known for their ability to adapt to various environments. They can survive for a long period of time without food and water, which makes them hard to eliminate once they have infested a home or business establishment.

Cockroach control methods include the use of pesticides that kill these insects by damaging their nervous system or digestive tract. However, there are other options available such as traps, natural repellents and baits that contain insecticides that work well against cockroaches without using chemicals that may harm humans and pets if ingested accidentally.
