Insects are one of the most diverse groups of animals on the planet and can be found in nearly all environments. The vast majority are harmless to humans but a few, like mosquitoes and ticks, are vectors for pathogens such as malaria, yellow fever and lyme disease. If you travel in to their habitats then there is a good chance that you will encounter them, so you need to protect yourself.
When walking and travelling in areas of high insect infestation the best way to prevent bites is to cover up any exposed skin. This is often impractical or undesirable in locations with high temperatures, so a skin applied insect repellent will be required. These come in various different forms such as gels, lotions and sprays for ease of application. Hotel rooms can be shielded with plug in electronic repellents that emit insecticides that are harmless to humans but lethal to insects. If you are lucky enough to have a balcony and want to sit outside at night then burning incense sticks, candles or coils impregnated with an insecticide or natural insect repellent will help keep biting insects at bay. If you are unlucky enough be bitten, then there are a range of soothing remedies and tools to mitigate discomfort and infection.
