Yes, hitting a fly can hurt it, causing injury or death, but they often escape due to their amazing speed and vision; even a glancing blow can cause lasting damage, and while they don't feel pain like humans, they do react to stimuli, with some studies suggesting pain-like responses in insects, making even near-misses potentially detrimental.
A 2022 review found strong evidence for pain in adult insects of two orders (Blattodea: cockroaches and termites; Diptera: flies and mosquitoes) and found substantial evidence for pain in adult insects of three additional orders (Hymenoptera: sawflies, wasps, bees, and ants; Lepidoptera: moths and butterflies; and ...
First, flies, like all arthropods, have exoskeletons which protect them. If you aren't "squishing" them, crushing the exoskeleton, you aren't going to kill them. In other words, you need to hit them harder.
Swatting a Fly Without Killing It May Cause It Pain for the Rest of Its Life, Study Finds. Barely missing a fatal slap at a bothersome fly might be a headache for both of you, according to new research from scientists at the University of Sydney.
No, Insects Do Not Feel Pain.
The clearest evidence that insects do not feel pain is because of how insects respond to injuries. For example, an insect with a damaged foot doesn't limp, and insects with crushed abdomens continue to feed and mate.
Using the eight criteria, they found that certain orders – including Diptera (flies and mosquitoes) and Blattodea (cockroaches and termites) – satisfied six of eight criteria, constituting “strong evidence for pain”, and in fact scoring higher than some animals recognised in the new animal welfare legislation.
Kissing bugs spread the Chagas parasite through their poop and NOT their bite. For this reason, don't squish kissing bugs! If you want to kill a kissing bug, put it in a paper towel or plastic bag first.

In a new study, the researchers report they've teased out the cell types contributing to a persistent aggressive state in female fruit flies, showing that some cells associated with aggression can cause flies to remain angry for up to 10 minutes.
According to Rod Preece, the children's book Insects and their Habitations: A Book for Children, published by the Society for Promoting Christian Knowledge in 1833, taught that unnecessarily harming insects was a sin against God and that children should assist insects they encountered in distress rather than harming ...
As Dr Erica McAlister, our Senior Curator of Diptera, puts it in her book The Secret Life of Flies opens in a new window, 'if it weren't for these little organic munchers we would be knee-high in dead bodies'. In fact there's a whole range of insects that exhibit necrophagous behaviour, including some flies and wasps.
Mosquito
The deadliest insect is, in fact, the deadliest critter in the entire animal kingdom. It is the humble mosquito, which kills more than 700,000 people every year. Skeeters are vectors for a host of nasty diseases, including malaria, dengue, West Nile, yellow fever, Zika, chikungunya, and lymphatic filariasis.
It can be irritating when flies come buzzing into your home, but you should avoid killing them if at all possible, experts have said.
“Sexual interaction is pleasurable and rewarding for male flies in a similar way as mammals,” she said. These neurological reward systems are primitive, thought to have emerged long ago in the shared evolutionary history between human and fly. Fruit flies even engage in foreplay.
Flies are attracted to our pungent "cloud of effervescence," experts say. There's hardly a more irritating noise than the sound of a fly buzzing around your head. These tiny insects have the uncanny ability to track down humans and nimbly dodge our attempts to swat them away.
The Red Imported Fire Ant
Although an individual fire ant cannot kill an individual, “they are known to be one of the most aggressive insects that exists,” Rivers says. “They will actually chase you. They're among the top 10 threats to agriculture because they will destroy anything in their path.”
No. They have a tracheal system. On the body of the insect, you'll find holes in several places, called. These lead to tubes called tracheae that spread through the entire body.
Science shows that cinnamon is most effective as a fumigant, as flies hate the smell of cinnamon.
None of us like living with insects or rodents, but this is cruel. Insects or animals caught in these traps struggle against the glue trying to escape. Eventually, they succumb to injuries, exhaustion, starvation or dehydration over the several hours or days it takes to die. These traps are indiscriminate.
In a nutshell, he has found that these annoying pests seem to be able to survive freezing temperatures!
Chagas disease is curable if antiparasitic treatment is initiated early, in the acute phase. In chronic infection, the treatment and follow up can potentially prevent or curb disease progression and prevent transmission, for instance, during pregnancy and birth.
Bed bugs are not known to spread pathogens through their bites. Bed bug bites can be itchy and stressful. Do not squish a bed bug as it will release the blood and any pathogens it may be carrying.
Kissing bugs are a group of blood-feeding bugs that may bite (“kiss”) you on your face around your mouth, usually while you sleep. Although some aren't dangerous, some kissing bugs carry a parasite called Trypanosoma cruzi (T. cruzi), which can cause Chagas disease.
