This bugs are everywhere in my house and we've tried so many home remedies, but they won't leave. Can anyone help us!?
That is an Indian meal moth Plodia interpunctella. Family Pyralidae. They are very common household pests. https://www.doyourownpestcontrol.com/indian_meal_moth.htm They breed in grains or cereals. You need to look through your pantry, and find out what they have been breeding in. Seal up your grains and cereals in plastic, or put them all in the fridge.
This is probably a common flour moth or a similar pyralid species. It has probably laid eggs in some cereal-derived products (pasta, cous cous, but also rice, oatmeal and the like) of your kitchen. First of all, check carefully your pantry for infested food and throw it away. Then (from the above Wikipedia link):
None of the stages of the organism (eggs, larvae, adults) are very temperature tolerant and all can be killed by a week of freezing or by brief heating in a microwave or conventional oven when such treatment is practical. Scrubbing infested areas with a mixture of soap and water or vinegar is also effective. [...] Nontoxic traps are also available to monitor outbreaks. One type of trap is a triangular box with a pheromone lure and sticky walls inside. These traps are generally known as pheromone traps. In this case, male moths are attracted inside by the female pheromone (the lure) and then get stuck against the sticky walls inside the box.
From personal experience, it can be sufficient to check the pantry and seal all the cereal-derived food into plastic bags.
