No, chocolate is not poisonous for ants.
Both carpenter ants and acrobat ants will bite. The carpenter ant rarely bites a human and they are not poisonous. The acrobat ant is quick to bite and this can cause pain and itching but they are not poisonous.
yes
yes
No, of course not. Bullet ants are the most poisonous ants in the world and the bull ants *not bulldog* are the most dangerous.
No, it is venomous though. It is not medically significant.
yes i was bit by one
Red ants are not poisonous. Whilst they may be very irratating, and sitting on a red ants nest is far from pleasurable, red ants are not poisonous to humans. Red ants are aggressive and territorial, but to humans no real threat.
try spraying poisonous gas
Yes pickle is piosonous to the fire ant
All ants are in the family Formicidae, which simply is Latin for "ants". Some ants are in a part of the Formicidae family called the subfamily Formicinae. None of the Formicinae have proper stings, but thay all bite if you bother them. Many of them produce lots of formic acid, and often will squirt it into the places that they bite. An example of an ant that does not sting is the weaver ant, which bites powerfully and squirts formic adid.There are other subfamilies though; some of them also just bite, but others, like many of the Myrmicinae will bite, but also have a powerful poisonous sting. One example is the fire ant, Solenopsis invicta. Another is the bearded harvester ant, Pogonomyrmex barbatus, which has a very poisonous sting. Other poisonous stinging ants include the subfamily Ponerinae, and the bullet ant subfamily, Paraponerinae.
There are hundreds or thousands of kinds of ants called red ants, and some of them contain more poisons and worse poisons than others. Most things are a little poisonous, sometimes more than a little, for example cigarettes. Some of the kinds of beans we eat are so poisonous that when rats ate them uncooked, they got ill and in a couple of weeks they died. Other kinds would not kill anybody even if we ate them raw, but they still do contain a little poison. It is like that with ants. Most ants contain at least a little formic acid, which is nasty, and rather poisonous, while some kinds are nearly one third formic acid. Other kinds of ants contain far more dangerous poisons; the reason that poison-arrow frogs are poisonous, is the ants that they eat; if you take some of the tadpoles and raise them without poisonous food like the kinds of ants they eat, they grow up without producing any arrow poison. So, you could argue that red ants are poisonous, and so are black ants, but they are not generally so poisonous that we are more interested in their poison than in the way they can bite and sting. And by the way, the reason that ant stings hurt is that they inject poison.
