People think that detecting the presence of roaches is relatively simple. The idea would be to open a cabinet in the kitchen and discover many bugs running here and there. The truth is that cockroaches are very skillful at hiding from prying eyes. Cockroaches love dark and damp places, which they do not leave for long.Therefore, it might mean that when one starts noticing the bugs, there might have been an infestation for some time. Luckily, roaches do not manage to remain invisible forever. Before revealing themselves in broad daylight, these nasty bugs often leave numerous traces of their presence. The first signs indicating that the roaches have arrived in your home are unexpected smells, black spots, and marks that seem to have appeared from nowhere.According to a study by National Institute of Environmental Health Sciences, one sign often unrecognized as a symptom of cockroach infestation is an odd smell. Some people tend to think that the odour originates from moisture in the walls, old or damaged furniture, or poor ventilation systems. However, a rising number of cockroaches in the area can lead to a particular musty and oily smell.It is caused by pheromones – substances used by cockroaches for communication. The more cockroaches there are, the stronger the smell becomes. In many cases, homeowners report that the odour is not very pleasant, persistent, and hard to get rid of despite cleaning. If you keep smelling odd smells in rooms despite your attempts to make them clean, you might consider inspecting them for cockroaches.
The small black spots
Have you found tiny black spots after cleaning your counter or cabinet, just to find them again a few days later? The feces of cockroaches is usually confused for dust, pepper, or coffee grounds. The feces usually appears in kitchens, below the sink, inside cabinets, or near areas where there is food storage.Since the size of the spots is very small, they are hardly noticeable. But, clusters of black spots appearing in the same area could point to activity by cockroaches. Pest control specialists actually regard these droppings as one of the strongest evidences of an infestation by the cockroaches.
Weird brown capsules in d the corners
Cockroaches procreate rapidly, and unlike the misconception of egg-laying by most individuals, female cockroaches create egg pouches called oothecae. Small brown capsules are usually kept in cracks, beneath or behind furniture, refrigerators, or in any storage containers. At first sight, they can easily be confused for dead seeds or other forms of dirt and litter. It is common for homeowners to mistake these capsules for something else before disposing of them. One capsule alone may not seem like a huge concern, but there are several baby cockroaches contained in each egg case. Locating several capsules would typically indicate procreation of the pests within the house.
Your walls could have secret paths revealing them
During moist weather, the presence of cockroaches can result in smears on the walls, baseboards, and other surfaces along their pathways. They have been mistaken for grease spots and dirt but the fact is that they keep appearing on the same spots. So, if you discover yourself continually cleaning similar lines, you could be unknowingly cleaning cockroach paths.The places you should look out for would be those close to plumbing and underneath sinks and other kitchen appliances.
Damaged food packaging must not be overlooked
Cockroaches are scavenger insects. Their diet consists of crumbs, remnants of food, pet food, cardboard, paper, and even glue. If you observe small holes in food packages or torn cardboard and paper wrappings with no apparent reason, you might assume pests are the cause. Even though the same damage could have been caused by rodents, one must also suspect cockroaches if other signs of infestation are observed.
Spotting cockroaches in the daytime is a major alarm signal
Cockroaches are mostly nighttime pests. This means that they generally prefer spending nights searching for food. Therefore, finding a cockroach in broad daylight is usually seen as a major alarm signal. If a cockroach appears when it is light outside, there might not be enough space left in its hiding places to contain all its members.
