Problem: Article: In order to get rid of the flying ants for good, you will need to follow them back to the nest of the colony. Killing the colony of ants will provide you with a more permanent solution.  Understand that flying ants are only the sexually active forms of an ant species. In other words, they are not a separate species of ant at all. When you find the colony flying ants belong to, it will consist of mostly wingless ants. If you want to kill the flying ants, though, you need to kill the wingless colony those ants come from. Try to follow ants back to the colony by observing them. If you can find the anthill they come from, you can attack the hill directly. If you are unable to find the actual nest, though, you can still attack flying ants at the source by spreading poisons that flying ants and wingless ants can take back to the colony. Ant bait and other commercial poisons are effective against flying ants as long as they are labeled for use against ants in general. Look for pesticides that the ants will carry back to the nest since these will do the most damage.  Ant baits are among the most effective ant killers, especially when you are dealing with flying ants. The ants take the bait back to the colony, where the queen consumes it and dies. After the queen dies, the rest of the colony soon follows. Ant baits come in the form of gels, granules, and stations. Most are safe for use around pets and children, but nonetheless, you should keep them out of reach when possible. Note that these baits can be sugar-based or protein-based, and different bases will attract different species of ants. If one does not work, try the other. Always follow the instructions carefully to avoid misusing the poison in a potentially dangerous way. Borax is highly toxic to ants, but if you mix it with something sweet, the ants will not detect the poisonous scent and will carry the sweet-smelling food back to the colony. When the queen and the rest of the colony eat the borax, the ants will die off.  Combine equal parts borax and sugar. Slowly add water to the combination, mixing continually, until a paste develops. Spread this paste onto a piece of cardboard and place the cardboard in an area that flying ants are known to linger in. The ants should be drawn to the paste, and if it works correctly, they should take some back to the rest of the colony. Note that borax pastes like this tend to dry out in a few days, so you might need to make more if the first batch does not take care of the probably right away. Be careful when using borax around pets and small children, since it is poisonous to them, as well. After you find the ant colony, pour boiling water over the anthill. Ants faced directly with the boiling water can be scalded, and the rest will likely move away from the area in response to the new threat and the damage you just inflicted.  The water should be more than just a little hot; it needs to be boiling. Boil as much water as you can in a kettle. As soon as the water is ready, remove it from the heat and take it directly to the anthill. Douse the anthill with the water while it is still as hot as possible. Consider placing a flowerpot upside down over the anthill before you boil the ants out. Pour the water onto the anthill through the drain hole at the bottom of the flowerpot. Doing this traps the ants while protecting you against bites and stings issued by any escapees. Baking soda is another material that can kill ants. By mixing it with powdered sugar, you mask the odor and cause flying ants to take it back to the queen and to the nest. The ants that eat it will die. The baking soda reacts with an acidic substance ants naturally carry around inside for the sake of protection. When the baking soda mixes with this acid, a violent reaction develops and kills the ants as a result. Certain types of artificial sweetener are extremely toxic to ants, yet the sweet scent is often enough to lure them in. The artificial sweetener gets carried back to the queen and to the nest, and all the ants that consume it die off.  Aspartame, in particular, is known for acting as a neurotoxin to ants. Mix a little artificial sweetener with some apple juice, adding just enough apple juice to form a paste. The ants will eat some of this paste and carry some back to the rest of the colony. Once consumed there, the ant population will dwindle.
Summary: Track down the nest. Use a commercial pesticide. Create a trap of borax and sugar. Use boiling water. Set a trap using baking soda and powdered sugar. Kill the ants with artificial sweetener.

Problem: Article: Smoking a drug can cause red or watery eyes. Pupils that are constricted or dilated can be a sign of narcotics, stimulants, or club drugs. Check for rapid or unnecessary eye movements. Involuntary eye movements, or nystagmus, are symptomatic of many kinds of drug use. If someone is wearing sunglasses inside or in the shade, they might be trying to hide red or otherwise affected eyes. Someone who has smoked marijuana might smell sweet, smoky, or skunky. A chemical or metallic smell might mean they inhaled a toxic household product, such as glue or paint thinner. A smell of incense, air freshener, or powerful perfume or cologne might be intended to cover up the smell of a drug that has been smoked. Listen to his swallowing and observe the way it moves. Salivation and lip smacking can be signs of dry mouth, a sign of drug use. Licking of the lips, frequent clenching of the teeth or twisting of the jaw might mean that someone is high on club drugs. A bloody nose with no other apparent cause can mean that someone has snorted a drug, such as cocaine, meth, or a narcotic. A runny or congested nose can have many causes but combined with other symptoms it could signify that someone is high. Frequent rubbing of the nose can also be a sign. Someone who has snorted a drug might have powder on her nostrils or upper lip. Shaking hands can be a sign of club drugs, inhalants, or hallucinogens. Palm sweat can be a sign of intoxication. Burned fingertips can be a sign that crack cocaine was smoked. Pulse, rate of respiration, temperature, and blood pressure can all be affected by drug use. If you feel safe touching the person in question, take his pulse and check his temperature. Cold, sweaty skin is one sign of drug use. An increase or decrease in blood pressure, an increased heart rate, or slowed breathing can all be signs of drug use. Some drugs can cause chest pain, and even heart attacks. Seek medical help for someone who seems to be experiencing pain in his chest. People who use drugs such as methamphetamine, bath salts, or heroin often inject their drugs, which leaves track marks. Check for darkened veins, lesions, and bruising around the veins. Lesions that are open and in the process of healing can be signs of recent drug use. Sores or a rash on the mouth or nose can also be a sign of habitual drug use. While pipes, rolling papers, syringes and rubber tubing might be easily recognised as drug paraphernalia, the unwarranted presence of household objects can also indicate recent drug use. Bent spoons, eye droppers, and cotton balls may be indicative of narcotic use. Razors, handheld mirrors, and tiny spoons might indicate the use of stimulants. Pacifiers, candy necklaces, and lollipops may be used by people on club drugs, such as Ecstasy, that cause the jaw to clench.
Summary:
Look into the person's eyes. Smell the person. Observe the person's mouth. Observe the person's nose. Observe the person's hands. Check the person's vital signs. Check for signs of habitual drug use. Check for drug paraphernalia.
