A bed bug infestation can be a nightmare. The good news is that, other than giving you sleepless nights and itchy bites, bed bugs aren't likely to cause severe harm. However, that doesn't mean they'd be good bedmates, and you should take steps to eradicate them the moment you find out you have a problem. To deal with an infestation, bed bug sprays can help.

Bed bugs are tiny critters that live in fabrics such as mattresses, beds, furniture, clothing, or other personal belongings. They feed on human blood, which is why a telltale sign of an infestation is waking up with red, itchy, and sometimes painful swollen bites. Another sign to look for are blood spots or small brown spots on surfaces (bed bug faeces).
If you think you have bed bugs, the first step is to remove all bedding and check for signs of excrement on the mattress, bed frames, and the surrounding area. Next, wash all the fabrics at a high temperature (60°C) and put them in the tumble drier as heat will kill them. Dry cleaning can also help to get rid of bed bugs.
Deep clean the bed and surrounding areas, paying attention to cracks and crevices where bed bugs may hide. If it's a minor infestation, applying bed bug spray to the mattress, bed and affected areas is essential to completely eradicate them and prevent them from coming back. If your mattress is heavily infested, cover it with plastic and dispose of it to contain the infestation, or call in professional help.
Got a pest problem in the garden? Here are our go-to insecticides for the garden!
Pyrethrins (cypermethrin and tetramethrin) are a group of synthetic variants of pyrethrum, a natural insecticide found in chrysanthemum flowers which can be used to eradicate a number of household pests. When a pest ingests or comes into contact with these substances, it shuts down their central nervous system, causing paralysis and eventually death.
Applied properly and left to dry completely for 30 minutes to an hour, cypermethrin is safe to use around pets and children. Nevertheless, it can't be ingested and may cause irritation if it gets on the skin. Most sprays will also emit a pungent odour. Therefore, we advise that you wear protective gear such as a mask, gloves and goggles, and always follow the instructions in order to use the insecticide safely.
For a completely chemical-free insecticide, go for a bed bug spray that uses natural ingredients, such as essential oils and herbal extracts. Bed bugs are naturally weak against clove leaf, cedarwood, lemongrass and peppermint, which repel and prevent them from returning.
Another benefit of natural sprays is that they don't leave a pungent, chemical smell. Instead, it usually leaves behind a lovely fragrance due to the oils used in the formula. On the downside, when it comes to managing a full-blown outbreak, natural formulas may not be as effective because they do not contain chemical insecticides.

As they contain powerful insecticides, bed bug sprays should always be used with caution. Although most are safe to use on household objects, always check the label for any cautions or indicators, such as possible staining. You may be in very close contact with the spray for an extended period of time, so it is important to find out whether the solution is safe and effective to use on the surfaces you want to treat.
Bed bug sprays are generally designed to kill the insects upon contact and treat the nest site along with surrounding areas in which insects may be hiding. However, although sprays for soft furnishings are popular, not all formulas can be used on mattresses due to the potency of various insecticides.
Before making your purchase, make sure to check whether it is suitable and safe for the task at hand. If you have a specific application in mind, look for a formula that will be effective in treating that particular area. Additionally, opt for a non-staining formula to prevent damage to surfaces and furniture.
