Why Are We Afraid Of Spiders?

What Do Spiders Eat?

We are generally afraid of spiders in our homes because we don’t want to be bitten, but luckily, humans are not on a spider’s menu. They also don’t bite as frequently as you would believe. Can you blame them for coming into your house if you have any of their favorite foods?

Most people would agree that your home is not a good place for them to live. The easiest method to keep your home spider-free is to learn about their eating patterns and eliminate the foods that attract them.

Mosquitoes, flies, moths, and even other spiders make up the majority of a spider’s food. Despite the anxiety that these eight-legged predators can instill in humans, they’re valuable creatures to have around since they can help keep other pests out of your house.

Species That Are Commonly Found

Yellow Sac, black house spiders, brown house, hobo, cellar spiders, common house spiders, black widow, brown recluse, and wolf spiders are all common house spiders.

The majority of the ones you come across are harmless and prefer to live their lives alone, avoiding human interaction. Knowing how to react and when to seek medical treatment if you come across a harmful variety can help you avoid major harm or injury.

What Food Do Common House Spiders Consume?

What Food Do Common House Spiders Consume?

Almost every spider hunts its prey. The majority of spider food consists of insects, however, some larger foreign species can consume small animals such as crickets, grasshoppers, lizards, frogs, rodents, or birds.

The spiders you’re most likely to see around your house are those that consume the insects you don’t want to see. They aid in pest control by restoring equilibrium to your home’s environment by trapping flies, mosquitoes, moths, and other insects in their webs. 

Spiders consume hundreds of millions of tons of insects every year. Can you imagine how different the world would be if they didn’t assist us to get rid of bugs?

Cobwebs are the primary food source for spiders, so keep an eye out for them around your home. They weave webs to catch flying insects, creepy crawlies, and whatever else comes their way. 

Although not all species trap their food in this manner, many of the species you’ll encounter near your house do. Other species rely on hunter-gatherer tactics.

House spiders prefer to spend their lives indoors, where they can easily locate insects (food) and water. They’re a specific type of spider that has evolved to spend their entire life indoors.

As a result, lowering the number of insects that enter your home and limiting a spider’s food source can be accomplished by closing entry holes in windows or doorways and staying on top of your spring cleaning by eliminating clutter building around your home.

How Frequently Do They Consume Food?

Spiders do not require frequent feeding and can go for weeks without eating. If insects are accessible, though, they will eat them often. They can eat up to four times every day. 

They require water in addition to the moisture they obtain from their food. And if they don’t eat for a time, the water becomes even more important. Spiders also prefer to congregate around water sources because their food is drawn to it.

How Spiders Catch Their Prey?

Some spiders trap prey in their webs whereas others hunt their prey down.

Spiders have two little mouthpart appendages near their mouth called pedipalps in addition to their eight legs. While the spider attacks its meal with its teeth, the pedipalps keep it in place. 

The insect’s insides are liquefied by a digesting enzyme injected by the fangs. The spider can then consume its meal as if it were a potent protein shake. The bug may appear normal once they’ve finished eating, yet all that’s left is an empty exoskeleton.

How to Avoid Them?

You can utilize what you’ve learned here to keep spiders and other household pests out of your home without introducing dangerous chemicals. Natural pest treatment and prevention is effective and safe for people, pets, and the environment.

Spiders’ Feeding Habits

You’re probably used to eating three meals a day, with an afternoon snack thrown in for good measure. Imagine that instead of going to the supermarket to buy food, you sat motionless on a large web, waiting for food to appear. Many spiders capture their food in this manner, and it can take days for them to catch their favorite prey: insects.

Because spiders are cold-blooded, their body temperature fluctuates with the weather. When it’s chilly outside and insects are scarce, they can conserve energy by remaining completely still. 

Humans, on the other hand, are warm-blooded. Our body temperature remains relatively constant regardless of the weather, and we must eat daily to maintain our energy levels.

Some spiders will eat relatively small creatures such as birds, frogs, lizards, and centipedes in addition to insects such as ants, flies, mosquitoes, and bees. Many of them will eat other spiders! 

Spiders can be finicky eaters. They exclusively eat creatures that are alive or that they have just killed, and they rarely ingest plant matter. They are known as carnivores because they solely eat meat.
