Can you stop ant death spiral?
The creatures are then unable to break free, owing to their lack of sight, and march around in a loop until they drop dead. What's more, it is possible to force them into this bizarre behaviour – though obviously it's an act of cruelty to the ants. You simply divert the ants into an enclosed space such as a plant pot.
An ant mill is an observed phenomenon in which a group of army ants are separated from the main foraging party, lose the pheromone track and begin to follow one another, forming a continuously rotating circle, commonly known as a "death spiral" because the ants might eventually die of exhaustion.
When an ant dies, its nestmates quickly pack it off. That way, the risk to the colony of infection is reduced. But how do they know its dead? Theory has held that dead ants release chemicals created by decomposition (such as fatty acids) that signal their death to the colony's living ants.
When army ants, which are naturally blind, lose track of the pheromone scent that keeps them in contact with their main foraging party, they begin to follow one another, forming a continuously rotating circle. With no other cues to tell them what to do, they will continue in this circle till they die of exhaustion.
What is this? As for their strength, a single ant can carry up to 20 times its weight but because of their huge number, large prey can be turned into bones within minutes. The interesting fact about them is that they have two phases of activity that they go through depending on the stage of their young.
Ground cinnamon can also be a useful tool to remove an ant scent trail. Ants hate cinnamon. They'll go out of their way to avoid any cinnamon-scented or coated areas. Spread cinnamon along the ant trail, including cracks and openings.
What Happens to Ants When They Lose Their Colony? Ants who lose their colony will die (most of the time). If they're out foraging, and suddenly lose their trail back to the colony, will be doomed. They'll probably look for the way back, but the chance of them stumbling upon the colony will be very small.
It could be the chemicals in the marker act as an ant repellent. The ant is repelled by the line and refuses to cross it. It makes sense that ants respond to any novel or harmful chemicals by backing away or avoiding them.
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.
Well, ants don't “scream” because they only communicate using pheromones or certain sound signals. What most people consider as “screaming” in ants is a type of chirping sound that's known as stridulation.
Do ants eat their own dead?
Ants usually only eat their own dead when there's a food shortage. Many ants eat their own in order to recycle their brethren into nutrients for the colony. While most workers prefer protein from live sources or meat from decaying corpses or other insects, they sometimes do tend to cannibalism.
Killing ants will, definitely, attract more ants because the dead ants release pheromones that attract or rather alert, nearby ants.

From the data that has been collected thus far, it is concluded that it is not so much the beat or the tempo of the music that affected the ants as we thought, but it was the decibel level that affected them the most.
Ants don't have ears
But that doesn't mean they are deaf. How do ants hear? Ants use vibrations to hear, using them when foraging for food or as an alarm signal. Ants use the vibrations in the ground to hear by picking them up in the subgenual organ which is located below the knee.
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.
Compared to vertebrates, ants tend to have blurrier eyesight, particularly in smaller species, and a few subterranean taxa are completely blind. However, some ants, such as Australia's bulldog ant, have excellent vision and are capable of discriminating the distance and size of objects moving nearly a meter away.
Death spiral is a condition where the structure of insurance plans leads to premiums rapidly increasing as a result of changes in the covered population. It is the result of adverse selection in insurance policies in which lower risk policy holders choose to change policies or be uninsured.
