Some pests are more obvious than others. For instance, ants will make an appearance wherever crumbs are present, while mosquitoes will happily breed where there’s stagnant water. But, other pests are not so easy to spot. Roaches will scatter and hide once the lights are flicked on, and bed bugs will only come out while you sleep. Termites join this list too — often hiding in your walls, it’s difficult to know you have them until the damage is done, and the damage can be severe.
