Nature's Biggest Pests


From ants in the kitchen to pigeons on the stoop, pests torment everyone. They sting, bite, destroy things and carry diseases. We've selected some of the peskiest creatures you're liable to come across and offer tips on how you can safely get rid of them. The first step to a pest-free home is removing their life support: water, food, and shelter.
Overuse of <a href=http://www.livescience.com/humanbiology/ap_060518_antibiotic.html target=new>antibiotics</a> has developed this relatively <a href=http://www.livescience.com/humanbiology/050606_staph_survival.html target=new>new pest</a>, resistant to almost all antibiotics. Bacteria that cause staph infections, heart valve infections, and pneumonia have outwitted antibiotics in a classic example of <a href=http://www.livescience.com/othernews/051109_evolution_science.html target=new>Darwinian survival</a>: only the strongest survive an onslaught of antibiotics and are able to reproduce. Their offspring, <a href=http://www.livescience.com/humanbiology/050509_superbugs.html target=new>superbugs</a>, are most often found in hospitals, nursing homes, and other settings where people fall sick often. The best defense is surprisingly simple: <a href=http://www.livescience.com/mysteries/070104_soap.html target=new>Wash your hands</a>
As the largest single group of mammals on Earth, <a href=http://www.livescience.com/othernews/060616_clean_rats.html target=new>rats</a> damage buildings by making nests out of insulation, chewing electrical wires and causing fires. In the <a href=http://www.livescience.com/history/060803_medieval_torture.html target=new>Middle Ages</a>, millions of Europeans died after being bitten by rodent fleas carrying the plague bacterium. Hide your food and trash from rats, as they also transmit typhus, trichinosis, and food poisoning.
To nourish their eggs, <a href=http://www.livescience.com/animalworld/060710_mosquito_buzz.html target=new>female mosquitoes</a> feed on animal and <a href=http://www.livescience.com/humanbiology/050120_mosquito_sense.html target=new>human blood</a>, and in turn <a href=http://www.livescience.com/animalworld/061104_gb_insects.html target=new>transmit diseases</a> like malaria, dengue, and <a href=http://www.livescience.com/humanbiology/050606_west_nile_virus.html target=new>West Nile Virus</a>. Two days after a female lays her eggs, they are ready to hatch, but can withstand drying for months. Prevent hatchings by cleaning up pools of standing water. Fish can be introduced to gobble up the <a href=http://www.livescience.com/insects/ target=new>insects</a> too.
<a href=http://www.livescience.com/animalworld/061113_pigeon_homing.html target=new>Pigeons</a> carry <a href=http://www.livescience.com/humanbiology/051021_flu_birds.html target=new>diseases</a> that can inflict humans with weak <a href= http://www.livescience.com/humanbiology/060619_mm_killer_cells.html target=new>immune systems</a>, but their mess is their worst offense. Droppings deface buildings and can inflict long-term architectural harm. To avoid the foul dirt, don't feed the birds. Pigeon-proof buildings by replacing damaged roof tiles, sealing holes, and installing spikes or wires where they roost.
Rabbits gnaw on lawns, vegetables, herb gardens, and even plastic irrigation lines, and of course they <a href=http://www.livescience.com/animalworld/061114_mating_game.html target=new>multiply</a> like themselves. They also can spread a serious <a href=http://www.livescience.com/bacteria/ target=new>bacterial</a> illness called tularemia. To protect Australian farms from these invasive species, construction began in 1901 of the Rabbit Proof Fence, the world's longest-and apparently most inefficient- fence. Keeping rabbits out of a fenced backyard involves plugging every tiny hole.
<a href=http://www.livescience.com/animalworld/060328_cockroach_decisions.html target=new>Cockroaches</a> need just a crack in the wall as thin as a dime to carry germs into your home. Their ability to adapt is key to their 200-million-year history. Yet, they can only survive without water for a week. Make them thirsty by pouring Lysol into toilet bowls and down drains.
Deer eat their way through <a href=http://www.livescience.com/othernews/ap_060618_strange_deer.html target=new>gardens and lawns</a>, cause traffic hazards, and carry deer ticks that transmit Lyme disease. To keep them at bay, plant sweet-smelling plants that they dislike, such as lavender, rosemary and sage. In woodsy areas, tuck pant legs inside socks and check pets regularly for ticks.
<a href=http://www.livescience.com/animalworld/060508_mm_ants_rule.html target=new>Ants</a> create scent trails to communicate with each other and find their way home. When you spot an <a href=http://www.livescience.com/php/multimedia/imagegallery/igviewer.php?imgid=719&gid=47&index=0 target=new>ant path</a>, start at the food source and wipe away the trail with soapy water and a sponge. Ants also dislike Vaseline, chili powder, cinnamon, and boric acid, which can be used to block a trail entrance. These methods are unsafe, however, if you have small children.
While adult <a href=http://www.livescience.com/animalworld/060612_mm_fly_feet.html target=new>houseflies</a> help themselves to your food and drink, they defecate on your meal. In order to digest solid foods, they turn it into liquid by regurgitating it. These unsanitary habits transmit diseases. To defend against the, install screens on doors and windows, and cover your picnic basket.
Checking the sheets late at night is your best chance of catching <a href=http://www.livescience.com/animalworld/060807_ap_bedbugs_rise.html target=new>these critters</a> in the act of hunting down a midnight snack of warm blood. To stop them from crawling up your bed, coat furniture legs with Vaseline or mineral oil; on the floor, place a barrier of chalk or double-sided carpet tape around the bedposts.
