co*ckroaches are one of the most invincible insectson the planet, if not the most. They can survive long enough without food but less without water.

When food is unavailable, they minimize their activities and use their body energy for basic survival functions. Since theyare cold-blooded, the temperatures around them drive their body’s functions, and you’ll see them being active when the temperatures are high. Naturally, underthese circ*mstances, they become more active while consuming less body energy. However, these insects hibernate during the cold weather to save their energy reserves, especially if food isn’t available.

What Do co*ckroaches Eat In Your Home And What’s Their Favorite Food?

co*ckroaches feast on anything they find that is digestible and organic. This natural temperament makes them one of the most resourceful insects among the wider pool. While they consume every organic material, their most favorite meals include decaying food and waste.

Here’s a breakdown of what meals co*ckroaches can survive on in yourhome.

  • Decaying food: As mentioned above, decaying food pieces found in garbage cans and kitchen corners are a co*ckroach’s favorite meal. It contains all the important nutrients they need for their body nourishment, including starch, protein, sugar, and even water-based fluids. co*ckroaches also explore areas outside a home to feed on decaying plant matter. This habit makes them more lethal as they only use a home for shelter if there’s no food inside.
  • Cellulose-based paint and other starchy substances: Since cellulose-based paints are the new norm and most people are turning their attention towards them due to their sustainability and affordability, this increases the amount of food forthe roaches.

In addition to these paints, co*ckroaches can feed on other starch-based substances, including paper, cardboard, paper bags, human hair,and glue.

  • Feces: Pet potties or litter boxes athome are a co*ckroach’s food haven. Since they can’t differentiate between what’s disgusting and appalling and what’s not, they regard human and animal waste as excellent meals. Feces are organic substances that meet all their nutrient requirements and are great food sourcesfor these insects.
  • Human food: The dry and uncooked fooditemsyou store in cabinets and drawers provide meals for co*ckroaches. These pests can tear through plastic, paper,and foil to reach stored food.

However, water would need to be availableas wellsince they can’t digest and process dry food alone. Water forms an essential part of their diet, and if not available, they won’t make it past a week or even days.

What Do Roaches Feed On If There’s No Food?Do co*ckroaches Eat Their Dead?

Inthe absence of food, roaches usually turn to other organic sources for survival. As pointed out earlier, they’ll feed on anything digestible or starch-based, including paper, hair, feces,and decaying plant matter. However, if water is absent, these insects won’t survive longer than a week.

In cases of extreme starvation, co*ckroaches usually turn against themselves and feed on others of their type. They attack and kill the weakened ones to nourish their own bodies. Besides, females can lay up to 300 unfertilized eggs, which they largely use as meals. Adults also resolve to eat their nymphs in situations that prompt them to do so for survival.
