What Is Natural Insect Repellent?

i am so afraid of any kind of insect especially cockroaches and i want to act before i have a problem with it. What do you suggest i do to prevent the insects from even approaching my house?
If this happens, how do i minimize the problem?
Thanks

There is nothing more annoying than having a houseplant with an insect infestation and not knowing what to do about it. To prevent destruction from pesky insects, though, you must know what you are up against and what is effective to keep the pests away.

The best way to prevent insect stings is to avoid all stinging insects ... but that's hard to do, even if you do stay inside all the time.
Before we focus on the various tips and hints to prevent insects and pests in your shed, it is important to understand why this process is important. If you have a wooden shed, letting insects and pests roam about freely without any restriction in your shed can quickly cause structural damage. It will also become a health problem.
Pests and insects often borrow into the wood and leave the structure weaker. Further, the structure will become unsafe if you allow insects to infest the structure. You may face the problem of insect bites, rashes and other allergies. Further, if you have the shed very close to your house, you may find these insects attacking your house as well. Hence, it is important to treat this part of your house as any other room and take remedial action to keep it free of pests and insects as early as possible.
One advantage these two chemical compounds have over some plant-based insect repellents is their effectiveness at repelling ticks, including those that carry Lyme disease.

Insect repellent sprays are applied to the skin and clothing to discourage insects from landing on that surface. Many insects carry and spread diseases such as West Nile fever, Lyme disease, bubonic plague, and others. The use of repellents can help prevent and control outbreaks of such insect-borne diseases. Some repellents are very effective against pests, but contain synthetic ingredients that can be unsafe for humans. Natural insect repellents are highly effective, nontoxic alternatives that do not contain harmful synthetic ingredients.
One of the most common active ingredients found in synthetic insect repellents is DEET (N, N-diethyl-meta-toluamide). DEET is a powerful insecticide used in over 400 products. Although DEET is very effective as an insect repellent, its safety record is questionable. When applied directly on the skin, over half of DEET is absorbed into the bloodstream. It can cause side effects such as skin rashes, muscle spasms, nausea, lethargy, and irritability. Severe reactions can cause seizures or death. DEET is a moderate pesticide and studies have shown that it may not be safe for use in and around water sources. Therefore, the health concerns from use of DEET far outweigh its effectiveness against insects.
Natural, safe, and effective alternatives to DEET are available. Insect repellents can be made with organic, all natural ingredients that are not unsafe for humans. These products are made from naturally occurring sources that repel certain insects. Some of these ingredients act as insecticides, while others only repel pests. These natural insect repellents are made primarily from essential oils derived from plant sources. Most natural repellents are just as effective as DEET, and they have a huge advantage because the ingredients are not toxic to humans.
Insect repellents work by using a fragrance that insects naturally avoid. This odor helps to mask the human scent that initially attracts insects. Most natural insect repellents contain the aromatic oil of citronella. Citronella is an essential oil obtained from the leaves of the plant Cymbopogon. Its lemon-like fragrance is pleasant to most people, but offensive to mosquitoes and other insects. Citronella has been approved by the US Environmental Protection Agency as a non-toxic pesticide.
Other aromatic essential oils commonly found in natural insect repellents include lavender, rosemary, peppermint, cedarleaf, lemongrass, eucalyptus, pennyroyal, and bergamot. Research has also shown that neem oil is an effective repellent for mosquitoes. Other volatile plant oils that work well as natural repellents are cinnamon, castor, cedar, clove, geranium, pine, basil, thyme, and garlic. Soybean oil has no direct insect repellent activity, but it is often used as a fixative to extend the shorter duration of action of some essential oils. Products containing multiple natural repellents tend to be more effective for more insects than those containing only a single ingredient.
Most natural repellents contain water in place of alcohol as the carrier base. Water is less volatile and does not evaporate as quickly as alcohol. Water has less dermal absorption, which leaves more repellent on the skin. Water based products will last longer because there is less need to reapply. Also, many people are sensitive to the strong aroma of alcohol, so the water-based products have a more pleasant smell.
The use of insect repellents can help control and prevent outbreaks of insect-borne diseases. Many insects carry and spread diseases such as West Nile fever, Lyme disease, and bubonic plague. Natural, organic insect repellents that do not contain harmful synthetic ingredients are available, and are just as effective. Many repellent products also serve a dual purpose and contain sunscreen to protect the skin from the sun as well as from insects.
