How are Spiders Unique?

Now, many people, instead of getting scared of spiders, make them their pets. Yes, there are many spider species that are not harmful and can be adopted as pets.

You can keep your pet spiders in a cage under a controlled environment so you can feed them directly.

What do Spiders Like to Eat?

Before keeping the spiders as pets, it is essential to consider the fact that they are carnivores so they can hunt their prey to live and survive, and they like to eat mealworms, crickets, Superworm, and even roaches. These insects are healthy meals for the spiders, and they love to hunt, kill, and eat them.

But you can also feed your pet spider, and the food that your pet spiders love to eat depends upon its size, maturity level, and native environment. You can also make your spider addicted to certain insects by feeding them repeatedly; for instance, if you have bought Mealworms and Superworms for them, you can buy the same insects from the store regularly.

The insects must be stored live and then should be served to the spider as live bait, so they get pleased to hunt them on their own.

●     Insects for Small Spiders:

You can neither feed a random amount of insects to your spider nor any size. For smaller spider species, one well-grown cricket is sufficient for one meal. Even some species can spend several days eating one large cricket. It means feeding spiders isn’t anything strenuous; it can be expanded from every other day to one week.

●     Insects for Massive Spiders:

The spiders that are big in size; probably need two or more crickets, but it depends upon the cricket size. With time, it becomes easier to understand which of the insects is your spider’s favorite one, how much it can eat in one meal, and how often it really needs to be fed.

If you want to get a clue about its favorite insect, you can figure out the native insects of your spider.

How Frequently do Spiders Eat?

Just like the quantity of the food, it also depends upon the size and species of the spiders. If spiders are young, they will need food on a daily basis to build their metabolism and to aid in their growth.

But, when they are mature or learn hunting skills, they can be fed after every alternative day; it will help them to maintain a healthy weight. If an average-sized spider gets a cricket after every other day, they will feel happy and healthy.

Apart from being carnivores, spiders are also nocturnal, so you can feed them at night, but they prefer to hunt and move around the home in the early morning hours.

You can put one or two crickets at the place of the spider before bed; in the morning, you will find them fully fed and well slept. Providing them in the daytime is not even wrong, but chances are they will hunt the live prey at night, particularly if your spider is older.

Periodically, your pet will go on fasts and will not eat like its regular routine, and these fasts can prolong from a few days to a few weeks – vary for every spider.

There is nothing to be worried about their fasting routine as it happens when they are in the mood of homemaking and eating on their reserves.

The bodies of spiders change and acclimate to their environment; this way, their eating routine also keeps changing throughout their life.

How is it Possible for Spiders to Live So Long Without Food Or Water?

Spiders can live about four to eight weeks without food and for three weeks without water; actually, spiders can store water and food within them that help them use at the time of fasting or when they don’t have anything for them. If their food storage is consumed, still, they can spend many weeks without having access to food.

If you are feeding your spider after several weeks, you are supposed to give them the insect that is live and in a smaller size than usual. Your spider really likes to eat live insects because they are attracted by their movement. Moreover, the spiders like to eat insects that are smaller in size than their abdomen. If you give them large insects, they will overeat and get sick.

The following are different species of spiders and their ability to avoid in the absence of prey:

●     American House Spider

Often, the American House Spider keeps a special reserve of food stored once it is used up; they can still live four to eight weeks without food and water.

American House Spiders can survive this long because they get protein by eating their web.

●     Wolf Spider

Without food, Adult Wolf spiders are capable of spending more than three weeks; as far as water is concerned, they can spend a week without water. More than one week means they are pushing their limit.

●     Black Widow Spider

If the prey is scarce, Black Widow Spiders can spend almost a year without eating as they can lower their metabolism to meager metabolism rates. Averagely, spiders can live only one week without water but several months without food.

●     Brown Recluse Spider

Adult Brown Recluse Spiders can survive almost 1 to 2 years without prey.

●     Daddy Longlegs

Daddy longlegs spiders have the ability to regulate their metabolism according to food availability. On average, they can survive up to 2 months without drinking and eating food.

By pushing limits, these Mexican Red-Knee Tarantula spiders can survive without food for more than two years. If these spiders get water consistently, on average, they can live without water for almost five months.

How About Their Water Intake?

Water is necessary for spiders as they need it to stay hydrated, and they need water even more frequently than food; therefore, they try to get water from different resources.

Many spiders get their moisture from the prey they hunt; wild spiders get water even from dewdrops over the tree leaves, bushes, web. House spiders get water from the window sill, while the pet spiders are provided with a water dish.

Spiders are also sensitive to the water type, so when you give water to your spider, ensure that it is fresh and chemical-free. If your spider has not drunk the provided water, you are supposed to change it regularly.

Spiders of different species and sizes drink different amounts of water. A small spider needs a little water (like a cap of a small pet bottle) to quench its thirst, and this water is enough for a couple of days. Instead of the bottle cap, you can also use a shallow dish so the spider can easily access the wide space.

Thus overall, spiderlings or baby spiders can go for a month without eating but a week without drinking.

How Can Spiders Live Without Food or Water for So Long?

Spiders can live without food for so long because they evolve their metabolism according to their situations and environment in scarcity of food. A carnivorous diet and the low metabolism rate of the spiders help them live without food for a long time because they consume their available energy.

Like other organisms, spiders also need water, but many desert species die due to dehydration because their only water source is their prey. So, despite metabolism regulation, spiders need water to survive.

When It Comes To Food And Water Scarcity, What are Most Capable Spiders?

Almost all spiders are strong-willed and can last one to two months without food, but a few spiders are more capable of surviving in scarcity because they have low metabolism. Spiders with high metabolism have less chance of survival than those with low metabolism rates because they burn less energy and consume reserved food slowly.

When it comes to scarcity, the following are the spiders who can live longer:
