Groceries stowed, kids in bed, you take a moment on the deck to enjoy a spectacular sunset. But…nearby, a female mosquito has detected your breath. The bloodthirsty gang follows your carbon dioxide emissions to their source, forcing you to retreat inside with several itchy puncture wounds. To arm you for battle: the dope on the bugs we love to hate. Pain comes from the bite.
Mosquitoes delicately saw into our skin and fastidiously suck blood through a straw-like mouthpart. Blackflies and biting midges snip our skin, which hurts more; stable flies stab their way in; and the champions of pain, deer and horseflies, Kenora and cut with fearsome, weapon-like mouthparts.
The lasting itch comes from saliva, which contains an anticoagulant to keep blood flowing. Mosquitos inject it, and others slather it on the wound. Your immune system quickly attacks this foreign substance, raising an itchy bump. Dog ticks even secrete an adhesive that makes them harder to dislodge. Mosquitoes and the sometimes biting flies prefer flower nectar; however, they need protein from blood to produce eggs, so adult female mosquitoes, blackflies, stable flies, biting midges, horseflies, deer flies, and ticks search out humans and other animals.
Male stable flies do consume blood, as do male ticks and immature ticks of both sexes. While carbon dioxide, body heat, and skin odour are major draws for most biting flies, motion also lures them in, especially horseflies and deer flies, which use their huge eyes to detect action from a distance. They are particularly drawn to shiny, moving sucks think swimmers. Not ticks: These hitchhikers climb high on vegetation, raise their front legs, and hook onto us as we brush by them.
These clans of vampires transmit diseases including yellow fever, malaria, and river blindness, which in many parts of the world cause death and misery. West Nile virus is transmitted by the bite of an infected mosquito, and its symptoms in humans are either so mild that it goes undetected, or it manifests as flu-like; extreme cases are very rare, but the virus may lead to debilitation or death.
Everyone in affected areas is at risk of exposure, but the likelihood of having the more serious health effects is very slim. Another risk is Lyme disease, an illness caused by bacteria transmitted by the blacklegged, or deer, tick.
Latching onto and sucking blood from a passing animal, usually a bird or a mammal, the nymph or adult tick can acquire the bacteria or, if already infected, pass it on. The range of this tick is spreading, perhaps aided by global warming, but family pets and wildlife, especially birds, also help establish new focal points for Lyme disease by carrying ticks to new areas.
Treatment with antibiotics is usually effective. Untreated, the disease may progress to include arthritis, t swelling, cardiac illness, or cognitive disorders due to infection of the central nervous system.
A closer look: Blackflies are compact, less than half the length of most mosquitoes, and have a hump-backed profile. Action time: They usually emerge in mid-spring and last through June. Main biting times are early in the morning and late in the afternoon, peaking towards sunset. A screened bug hat is ideal any hat helps. A steady breeze, even a slight one, deters these poor flyers. Amazing fact: s of blackfly larvae in streams can be staggering, up toper square metre at lake outlets.
To kill one of these frustrating masters of agility, you have to swat hard enough to hurt yourself. Action time: Stable flies peak during the warmest part of summer. They like the bright light and heat of midday. Covering bare feet and legs helps, though these biters can pierce thin clothing.
They breed in manure piles on farms, but also along beaches in wet, rotting vegetation. Deer flies are just larger than houseflies and have patterned wings. Horseflies are bigger, up to three centimetres long, and they usually have clear or uniformly coloured wings.

Deer fly eyes are often iridescent red and green, while horsefly eyes may be striped with bright green. Action time: Early summer is peak time, and the majority of species are most active a few hours after sunrise and before sunset. Avoid the bite: DEET repellents give minimal protection.
Since deer flies often bite the head area, wear a hat and cover your neck. Unfortunately, both deer flies and horseflies have a particular love for windsurfers and swimmers. Amazing fact: The huge compound eyes of a horsefly may contain 10, photoreceptor units, or simple eyes, which gives them superior vision. A closer look: Mosquitoes are delicate, with a long, slender abdomen and tube-like mouthparts for sipping nectar or, if they are female, blood. Males are drawn in by the sound as they search for a mate. Action time: They are out from mid-spring to autumn frost, peaking in late spring; most are active around dawn and dusk.

Avoid the bite: DEET-based repellents work; citronella-containing liquids work for short periods. Amazing fact: Malaria transmission makes mosquitoes, after humans, the most dangerous animals on earth, killing aboutpeople a year. A temperate type of malaria once existed in Canada, mostly in southern Ontario and Quebec. With window glass and screens, the use of quinine, and the draining of marshes prime habitat for the mosquito genus that carries malaria— Anopheles for agriculture, malaria was elim-inated from most of North America around Now, our only cases are travellers returning from hot zones, but transmitting mosquitoes still exist in Canada, so outbreaks could occur again.
A closer look: Ticks resemble flattened, miniature crabs.

You are most likely to find one when it is attached to your body or clothing or dog. The time of year varies by species; American dog tick adults are more plentiful from spring to early summer, and adult blacklegged, or deer, ticks the ones that transmit Lyme disease peak in the fall. Avoid the bite: Stick to trails and more open areas and tuck in clothing. Strong, DEET-based repellent can be sprayed on pants, socks, and shoes.
Check your clothing and body daily. Remove ticks by seizing the head as close to your skin as possible with blunt tweezers and pulling. Removed early, there is little chance that ticks will transmit disease, but you should wash and disinfect the area of the bite. Systemic symptoms—including multiple rashes, a low-grade fever, neck stiffness, fatigue, and severe headaches—can appear two to six weeks after a bite from an infected tick, even if no rash developed earlier on.
Biting midges are usually barely more than a millimetre in length, but similar to the blackfly in shape. Avoid the bite: DEET-based repellents work.
Windy conditions will reduce bites from these weak flyers. What bugs us Pain comes from the bite. Why us?

Amazing fact: After a full blood meal, a tick may be 30 to 60 times its starting size. Action time: Mostly around dawn and dusk, especially in mid- to late summer. Related Articles.
