Pests truly live up to their name. Not only do they carry a variety of diseases that can be deadly, but they can also cause allergies and house damages that may cost you a fortune!

Common house pests in Malaysia like cockroaches can spread multiple diseases fast. Rats can carry extremely serious diseases like rabies and hantavirus. Insects can be vectors for dengue fever, salmonella, strep, Lyme disease and more.
If you’re wondering why your allergies aren’t getting any better, you probably have these pests to thank as they can also carry allergens into your home. Apart from their faeces that can cause allergic reactions, with dust mite dander and droppings being some of the most common indoor allergens, their shed skins can pollute your indoor air as well.
On top of all that, pests can also cause house damages, which will eventually devalue your property if the pest infestation is left untreated. Depending on pest types, some of the potential house damages caused by them include structural, fire, furniture, bedding, pillow and mattress damages.
House damages can devalue your home. Structural damage, for example, poses safety risks; who’d want to live in a house that can collapse at any moment? You might have a hard time finding a willing buyer with a good offer.
