Article: Though it's unlikely to happen, this warning bears mentioning: don't handle carpenter ants or their nests directly. Carpenter ants are not particularly aggressive and will not usually bite humans. However, when irritated or threatened, they can and will inflict a painful bite. Carpenter ants are also known to spray formic acid into bite wounds, increasing the pain. Though it's not the end of the world to be bitten by carpenter ants, you can avoid unnecessary pain by avoiding touching the ants or their nests unless it's absolutely necessary, in which case you should use long sleeves and gloves. The first step to exterminating a carpenter ant colony is to find it. To pinpoint the location of colonies in your home, look for ants, small holes, and piles of frass in the locations discussed in Part One, paying special attention to any areas that appear to contain moist wood. You can also test wood for infestations near the surface by firmly tapping. Wood with extensive burrowing can sound thinner or hollower than unaffected wood. Tapping can also agitate ants, causing them to leave the nest, where you may be able to see them more easily. Don't forget that mature nests often have smaller satellite nests nearby, which also must be located to ensure the entire ant infestation is exterminated. In the case of smaller colonies, or ones that are fairly easy to access, it's sometimes possible to simply get rid of the colony itself.  If the colony is outdoors, simply dispose of the affected wood carefully, using impenetrable materials like tarps to protect yourself from the ants as you handle the wood. If the colony has been located indoors, some pest control websites recommend using a vacuum cleaner's hose attachment to disrupt the colony and suck the ants out.  If using the vacuum cleaner method, be sure to carefully seal and dispose of the dust bag to keep any ants that survive from escaping. If you find a colony that has extensively burrowed through the wood in your wall, don't cut the wood out - you risk compromising the structural integrity of your house. Instead, call a professional. You may not always be able to find carpenter ant colonies. However, if you can find significant numbers of the ants themselves, placing insecticides in their trails can control and eliminate the colony. A variety of baits, traps, and other ant-killing products are available for sale to the general public - visit your local hardware store to check which options are available to you. Be very careful when using poison ant bait in houses with small children. Make sure that the child knows not to eat the poison, or, if s/he is too young to understand, keep the child under close supervision. If you can't quickly locate and eliminate the colony and you haven't had success with insecticides, it's usually best to contact a professional exterminator. Professionals have access to insecticides and other tools that aren't available to the general public, but, more importantly, their training and experience allows them to locate and assess carpenter ant infestations much more intelligently than the average person.  Keep in mind that certain methods that exterminators use to kill ants may require your family to temporarily vacate your house for a day or two. Don't delay in contacting a professional - the longer you wait to deal with a carpenter ant infestation, the larger the colony can grow and the more extensive the damage to your wood structure may be.

Use caution when dealing with carpenter ants. Locate the colony or colonies. Destroy or remove the colony. Use baits for ant colonies that cannot be treated directly. Contact a professional.

This is because, over time, a less healthy diet (containing, for instance, high amounts of processed foods, and one that is high in fat, sugar, and/or salt) can contribute to clogged arteries and overall diminished blood flow. On the other hand, you can improve the health of your arteries and your blood flow by incorporating healthy options like:  Vegetables Lean meats Whole grains Healthy fats (such as those found naturally in avocado, fish oil, nuts and seeds). Spicy foods contain capsaicin from hot peppers in them. This chemical increases blood flow throughout the body. This is why many people become flushed when they eat certain spicy foods. Most experts recommend 8-12 cups of water per day, and more if and when you are exercising (to compensate for lost fluid during exertion). Consuming enough water is key to keeping your blood volume up, which in turn helps to improve circulation.  Also avoid too much caffeine and alcohol, as both contribute to dehydration. However, if you notice swelling in your lower legs throughout the day, this is one indication not to consume too much fluid. If this is the case for you, speak to your doctor about appropriate fluid recommendations to maintain a healthy level of hydration. Keep in mind that there are many potential causes of swelling, so it is important to get a diagnosis and follow your doctor's recommendations.
