You do not have to travel to an exotic location to encounter those tiny deadly creatures. There are plenty creepy crawlers in our back yards or on a hiking trail that you should be aware of. Some of the most dangerous insects are right under our feet and we have no clue about them. Some of the deadly bugs to watch out for are, mosquitoes, Velvet ants and Fire ants.
You would think that mosquitoes are just pesky little insects but they do hold the record for the most human deaths per year. There are over 2500 different species of mosquitoes throughout the world, of which 150 species are in the United States . Culex pipiens or northern house mosquito is the most common species of mosquito found in urban areas. It appears to be primarily responsible for transmission of West Nile Virus to humans and birds, as well as to other mammals. Culexmosquitoes are painful and persistent biters which prefer to attack at dusk and after dark, and readily enter dwellings for blood meals. Worldwide, mosquito-borne diseases kill more people than any other single factor. In the United States , mosquitoes spread several types of encephalitis, dog heartworm, and malaria.

West Nile virus is a potentially serious illness. Experts believe WNV is established as a seasonal epidemic in North America that flares up in the summer and continues into the fall. About one in 150 people infected with WNV will develop severe illness. The severe symptoms can include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. These symptoms may last several weeks, and neurological effects may be permanent. Milder Symptoms in those who become infected are fever, headache, and body aches, nausea, vomiting, and sometimes swollen lymph glands or a skin rash on the chest, stomach and back. Symptoms can last for as short as a few days, though even healthy people have become sick for several weeks. Approximately 80 percent of people who are infected with WNV will not show any symptoms at all.
There is no specific treatment for WNV infection. In cases with milder symptoms, people experience symptoms such as fever and aches that pass on their own, although even healthy people have become sick for several weeks. In more severe cases, people usually need to go to the hospital where they can receive supportive treatment including intravenous fluids, help with breathing and nursing care. Milder WNV illness improves on its own, and people do not necessarily need to seek medical attention for this infection though they may choose to do so. If you develop symptoms of severe WNV illness, such as unusually severe headaches or confusion, seek medical attention immediately. Severe WNV illness usually requires hospitalization. Pregnant women and nursing mothers are encouraged to talk to their doctor if they develop symptoms that could be WNV.
Here are a few interesting facts about mosquitoes you may have never known. Hopefully these facts will help you the next time you go camping or take a hike in the wilderness.
- You're more likely to be a target for mosquitoes if you consume bananas.
- Biting activity increase by 500 times when there is a full moon.
- Mosquitoes dislike citronella because it irritates their feet.
- Mosquitoes prefer children to adults, and blondes to brunettes.
- Only female mosquitoes bite—they need the protein for their eggs
- The welt that appears after a mosquito bites is an allergic reaction to the saliva that is injected into your skin to prevent your blood from clotting.
- Light colors are less attractive to mosquitoes than dark colors; thus, mosquitoes are more likely to choose a victim wearing darker colors.
You may ask yourself, how do mosquitoes choose who to bite? The answer is mosquitoes are attracted by Carbon dioxide in our breath. They can detect this from great distances. When the female mosquito gets close, she makes a final choice using skin temperature, odor and other chemical or visual factors. If two people are outside together, one will almost always get most of the mosquito bites.
Here are a few tips to help keep you from being the next victim of a mosquito bite. On warm, sunny days, only screened windows and doors should be opened. Keep screens in good repair. If mosquitoes do get inside your house, they may be found resting on walls, under sinks, in closets, or anywhere dark. Use a commercial insect spray and or swat them dead. A commercial flying insect spray may be used in the patio and garden area. Personal application of insect repellent can provide relief. To make sure you are not breeding mosquitoes, empty or change weekly containers holding water, clean drainage courses to ensure moving water, and stock impoundments with mosquito-eating fish.
One unusual insect that is occasionally seen running around open areas in the yard during July, August, and September is the velvet ant. Velvet ants look like large hairy ants, but they are actually wasps. They differ from ants in having only a slight constriction between the thorax and abdomen and having straight rather than elbowed antennae. They may be seen in lawns or pastures, or occasionally wandering into buildings. These solitary wasps, as the name implies, are densely covered with short hair. They get their name from the hairs that cover their body and because they resemble ants. Males have wings but do not sting. The females are flightless but sting, and are often encountered while wandering on the ground. They are known for their extremely painful sting, the venom of which was jokingly stated to be powerful enough to kill a cow. In some places a few species are also known as cow killers or cow ants. They can sting multiple times and if handled, they produce a squeaking, chirping sound to warn would-be predators. The family can be recognized best in the female; they are the only wingless female wasps that have hair-lined grooves on the sides.

Velvet ants range in size from 1/8 inch to one inch. Velvet ants look like miniature walking cotton balls. The red, orange, yellow, black or white bristle-like hairs, known as setae, cover the entire body. Biologists call this type of coloration "aposematic" and they use the term to refer to conspicuous warning colors of animals that predators should avoid. Over 150 species of velvet ants occur throughout the United States , southern Canada and Mexico . At least three dozen species inhabit Arizona . They live in all parts of the desert from hot and dry to semiarid areas to shrub lands.
Female velvet ants are equipped with a very efficient and powerful stinger. The sting is curved and sometimes nearly as long as the abdomen, and with it they can inject a very potent poison. Their sting is not deadly but known to be very painful as like a wasp sting. Local pain and swelling are typical. Sensitive individuals may have allergic reactions following a bite or a sting. Clean the site with soap and water. Apply a cool compress. A paste made out of baking soda and water or meat tenderizer and water may relieve some of the pain. Other whole-body reactions occurring in the first hour after being bitten or stung must be seen in an emergency room. In most cases, these insects are not generally considered as pests, but they can occasionally invade residences, daycare or schools in large numbers. If these pesky ants are left alone, no harm is done. But if an individual tries to play with this insect or accidentally steps on one, the resulting sting will remind the offending human how this insect got its name.
Ants have been digging through dirt for a very long time. They burrow out of jungles, forests and into back yards of humans on every continent except Antarctica . Ant fossils date back to the times of dinosaurs. They are one of the strongest animals on Earth, with the ability to lift a seed five times its weight. Fire ants are social insects. They live in communities and depend on one another to gather food, help build the nest, raise and care for their young, and protect themselves from enemies. Without the support of their colony, a single fire ant could not survive for very long. Fire ants are known for their lively and aggressive behavior, swarming over anyone or anything that disturbs their nest, often attacking wild animals, baby animals, pets or people, in some instances, even killing them. Their painful stings affect about 40 percent of people in infested areas each year. 20 million people a year are stung by fire ants.
Fire Ants

When these pesky critters invade an area, they do it with a vengeance. There will be enormous numbers of them which can dramatically reduce populations of native ants, other insects, and even ground-nesting wildlife. Watch out. They invade homes, school yards, athletic fields, golf courses, and parks. They will damage crops and electrical equipment, costing humans huge amounts of money each year in repairs and eradication. Don't be fooled. Fire ants look like ordinary house or garden ants, but have some distinguishing characteristics.
Fire ants vary in size from 1/16 to 1/5 inch long. They are dark reddish brown in color on the head and body, with a darker abdomen. Fire ant mounds can be more than 15 inches high, 15 inches in diameter and up to 5 feet deep. When they are disturbed they become very aggressive and the biting begins; especially near the nest.
Fire ants bite the flesh of there prey, and this is done so quickly and sharply that there is little pain. What inflicts the burn is the venom injected by a stinger. The venom is water-insoluble and contains hemolytic factors that cause the release of histamine. These stings produce itching and redness immediately and a bacterial uninfected pustule at the sting site after several hours. The venom also contains several allergenic proteins that can cause anaphylaxis in patients who are allergic to the proteins. Antigenic similarity exists between these proteins as with bee and wasp venoms. The natural course is for the site to burn for several hours, then over 24 hours a boil develops with itching, and over several days if not scratched the lesion will slowly disappear. Scratching can introduce infection and should be cleaned with alcohol. Rarely, patients will have an allergic response immediately or over the first few hours. The symptoms of this are difficulty breathing, light headedness and weakness. If allergic reaction occurs immediate medical attention by calling 911 is indicated.
If you see a fire ant nest move rapidly away from the nest. Quickly remove or kill ants on skin and clothing, to prevent further stings. If you are stung wash the area gently with soap and water to rid the skin of any venom on it. Disinfect the bite with alcohol and place a cool cloth or ice cloth on sites for 15 minutes. Try dabbing the site with one of the following: diluted (1:1) bleach solution, Kleen ‘Em Away Naturally, calamine Lotion, Enzyme cleaner or meat tenderizer. Consider spraying a topical to the area to help relieve the itching or take some form of antihistamine like benadryl. Do not scratch the abscess because this can lead to infection. Be careful to avoid fire ants, when out scan the ground for mounds or other evidence of these vicious pests. The sting is painful and the pustule persists for about a week. These ants do more than ruin a picnic, so be prepared for the inevitable bite and sting.
