Spiders are every day in our homes, so you may be worried about how dangerous they are for hamsters, whether they can hurt them and whether they are a threat to your pets.

Can Spiders Harm Hamsters?

Spiders are not a great threat to hamsters, but we still have to be careful because they can cause stress and infections by biting our pets. Larger spiders can bite hamsters and injure them, while small spiders are not dangerous for hamsters because they cannot penetrate their skin.

Spiders usually run away from hamsters because our pets are much bigger than them. If hamsters see a spider in their cage, they can easily eat it.

In today’s article, you will find out if spiders are dangerous for hamsters, if they can bite our pets and how to keep spiders away from their cage.

Do hamsters attract spiders?

No, hamsters are not attracted to spiders, they are attracted to heat, and they appear in warm places in our home. Although there are spiders in homes, they very rarely come into contact with hamsters.

The spiders are not interested in coming to the hamsters because they are not useful, they are interested in the food, and the food of the hamsters does not satisfy their needs at all.

Spiders can appear in the hamster cage if you feed your pets with insects, then larger spiders can come. Since hamsters mostly eat dead insects, it is not food to attract spiders, they like to eat live insects or if they have just died.

Spiders hunt live insects with their distinctive webs and then eat them.

Is my hamster afraid of spiders?

No, hamsters are not afraid of spiders, it’s more the other way around, that is, the spider is afraid of hamsters.

Indeed, the nature of hamsters as prey animals is always suspicious of everything in their environment, so it is with spiders, but in reality, they are not afraid of them.

On the other hand, spiders are afraid of hamsters and because they have excellent natural survival instincts they see anything bigger than them and hamsters as a threat.

Spiders are cautious and they will make a web as close as possible to your pet, in a dark corner or some other similar place where it is harder to notice them.

How harmful are spiders to hamsters?

Spiders, especially small ones, do not pose a threat to hamsters, they are too small and cannot pierce your pet’s skin with their jaws.

Bigger spiders are a little different story, they have stronger jaws and can cause pain to hamsters if they bite them. If bigger spiders bite the hamsters, your pet will feel unpleasant pain and get upset.

The biggest problem from this kind of bite is causing stress, which affects the health of the hamsters. When hamsters are under stress, they are susceptible to illness and the appearance of various diseases, such as the wet tail, which is dangerous for their lives.

A wet tail if not treated immediately can kill the hamster in a few days, so stress from spiders can be a serious threat to their health.

Can spiders bite hamsters?

It depends, smaller spiders will not bite the hamster, while larger spiders may.

Most spiders are harmless and will not bite the hamster, but some spiders may. Small spiders have very small fangs and cannot penetrate the hamster’s skin.

Larger spiders have fangs that can pierce the hamster’s skin, which is not good for your pet as spiders are poisonous and can cause problems.

We must emphasize that spiders bite if they feel threatened by the environment, in our case, it is the hamster.

When spiders bite a hamster their toxins enter the hamster’s body and can cause problems such as gastrointestinal damage and infection in your pet’s mouth.

When spiders bite a hamster, your pet may be lethargic, stop eating, and have pain and swelling in the places where they were bitten.

If hamsters are bitten by spiders, they will be in pain and hide in their hiding places and it will be difficult to notice if there is a problem with your pet. Hamsters are taught to always hide their pain because they think that predators will catch them more easily.

If you notice that the hamsters have any health problems and you notice spiders near them, you should immediately take them to a veterinarian to examine them.can spiders harm hamsters
