Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.
Ants don't have complex emotions such as love, anger, or empathy, but they do approach things they find pleasant and avoid the unpleasant. They can smell with their antennae, and so follow trails, find food and recognise their own colony.
Summary: Scientists have known insects experience something like pain, but new research provides compelling evidence suggesting that insects also experience chronic pain that lasts long after an initial injury has healed.
As far as entomologists are concerned, insects do not have pain receptors the way vertebrates do. They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged. Even so, they certainly cannot suffer because they don't have emotions.
When ants sense danger, they want to investigate the cause of death before carrying the dead ant away to the midden. Thus, it is not good to kills ants in your house because it will just make more of them come.
These are chemicals that send signals to other ants. Pheromones send messages of a food source, sexual desire, and death. It is advised not to squash ants, doing so will only release pheromones and trigger more ants to come to the location and cause more trouble to you and your family.
In jurisdictions where insects are covered by the state animal cruelty statutes, the needless, intentional killing of an insect is illegal and may carry a fine or even imprisonment. Whether charges are filed and the case is actually prosecuted is a separate issue, however.
Ants become the pallbearer
After a few days the dead ant is carried off and placed on the “ant graveyard” by the other dead ants. This may seem like ants have complex feelings and need a few days to grieve before they dispose of the body, but in reality it's far more chemical than that.
In fact, there's mounting evidence that insects can experience a remarkable range of feelings. They can be literally buzzing with delight at pleasant surprises, or sink into depression when bad things happen that are out of their control.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.

Most likely, yes, say animal welfare advocates. Lobsters belong to a family of animals known as decapod crustaceans that also includes crabs, prawns, and crayfish.
Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry.
Individual ants have tiny brains but together the many ants of a colony can exhibit remarkable 'intelligence'. Ants exhibit complex and apparently intelligent behaviour; they can navigate over long distances, find food and communicate, avoid predators, care for their young, etc.

While ants with normal receptors continued to recognize and fight ants from other colonies, ants with blocked or over-activated receptors displayed dramatically reduced aggressive behavior. “Accepting friends and rejecting foes is one of the most important decisions an ant worker must make,” said Ferguson.
The average lifespan of an ant can be anywhere from a few weeks to 15 years. That depends on the species, the role the ant plays and the availability of food sources. For instance, a black garden ant can live almost two decades, while fire ant workers are expected to live less than a month.
Ant colonies have specialised undertakers for the task. They usually carry their dead to a sort of graveyard or take them to a dedicated tomb within the nest. Some ants bury their dead. This strategy is also adopted by termites forming a new colony when they can't afford the luxury of corpse carriers.
Ants are good at communicating, and an ant dying lets its fellow colony members know about death. What is this? Ants, however, do not come to the scene of death to attack you or seek revenge. On the contrary, ants come near the dead and as a response to any danger.
To the naked eye, ants deal with their dead much like humans. When a member of the colony dies, the carcass will lie where it fell for a period of roughly two days. In the fashion of a wake, this time period presumably gives the other ants time to pay their respects to their fallen comrade.
Ants transport their dead there in order to protect themselves and their queen from contamination. This behavior has to do with the way ants communicate with each other via chemicals. When an ant dies, its body releases a chemical called oleic acid.
When an ant is injured in a fight, it calls its mates for help by excreting a chemical substance which makes them carry their injured comrade back to the nest. Erik T. Frank already described this rescue service in 2017.
Cannibal ants that were first discovered in a bunker in 2013 now have a boardwalk to freedom. Scientists know wood ants in particular often consume their fellow ants' corpses. Ants are suspiciously smart, using collective action to find resources like food.
Use natural ant repellents.
A cinnamon stick, coffee grinds, chili pepper, paprika, cloves, or dried peppermint leaves near the openings will repel ants. You can also squeeze the juice of a lemon at the entry spot and leave the peel there. Planting mint around the foundation of the house will also keep ants away.
More than 90% of hurt ants recovered to emerge from their nests and march again in future raids, the researchers report today in Science Advances .
