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.
Killing ants will, definitely, attract more ants because the dead ants release pheromones that attract or rather alert, nearby ants.
You're only addressing part of the population
Even if you treated that area of your structure where ants are being noticed, doesn't mean you are addressing where the colony is located. You may be finding the 3% of the colony that is foraging, but you're missing the 97% living somewhere else.
cerasi infestations have noticed that these ant pests are inexplicably difficult to kill. When workers from this species are stepped on they often regain activity after a few seconds, and this may be due to an unusually durable exoskeleton and/or the relatively small size of worker ants.
Ants, bees, and termites all tend to their dead, either by removing them from the colony or burying them. Since these social insects form densely crowded societies that face many pathogens, disposing of the dead is as a form of preventive medicine.
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.
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.
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.
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.
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.
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.
So, what happens when a queen ant dies? The answer is straightforward, the colony will eventually die as well. Ants don't flee to another territory or nest if their queen passes away. Instead, they continue bringing resources back to their settlement until they die of old age or external causes.
Entomologists and ecologists argue that we literally can't live without them. Ants live in terrestrial habitats throughout the world, and scientists have described and named over 12,000 species in the family Formicidae.

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 the ants are crushed, a unique odor becomes detectable; some describe the smell as rotten coconut, others say it smells like ammonia. They are polygenic (multiple queens within one colony), which allows them to grow their colonies at an incredible rate; a single colony can have as many as 10,000 workers.
The short answer is ants have something similar to blood, but scientists call it “haemolymph”. It is yellowish or greenish.
Ants, like other insects, have a heart that pumps hemolymph rhythmically.
Some ants, like leaf-cutters, use their feces as manure for gardens that grow fungal food, but only certain “sanitation workers” are permitted to handle it. Ants in general are well known for their cleanliness—disposing of the dead outside the nest and leaving food scraps and other waste in special refuse chambers.
Do ants scream in pain? 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.
While these insects don't literally scream, they actually produce sounds. Scientifically speaking, there are several species of ants that normally stridulate. These are shrill and repetitive sounds that are produced when the ants strike their body parts on certain areas of their colonies.
Many have the doubt that “does ants have brain?”, yes, they do have brain and it is very small that have 250,000 neurons. It is very less compared to human brain, but it is too large compared to other insect species. These ants have thinking ability and they can follow their routine with their colony.
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.
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.
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.
