Females have an estimated adult lifespan of 180 days, while males have an adult lifespan of about 160 days. Cockroaches are one of the oldest living insects on the planet. Their life cycle plays an important role in their ability to survive and populate the earth.
American cockroaches can live for about one year while German cockroaches are estimated to live for about 100 days. On average, cockroaches can live for a month without food but only a week without water. Cockroaches can feed on a variety of materials so starving cockroaches as a means of pest control is not effective.
Placing pandan leaves and moth balls around the house
There are smells to keep roaches away. E.g. pandan leaves, moth balls, peppermint oil, baking soda or even bay leaf.
Peppermint oil, cedarwood oil, and cypress oil are essential oils that effectively keep cockroaches at bay. Additionally, these insects hate the smell of crushed bay leaves and steer clear of coffee grounds. If you want to try a natural way to kill them, combine powdered sugar and boric acid.
Boric acid is a powerful natural home remedy for getting rid of roaches overnight. Mix equal amounts of boric acid, flour, and sugar until it becomes a dough-like consistency. Place small pieces where the roaches can feed on them.
The World Health Organization also advises against crushing them, for reasons of hygiene. According to the body, which classes cockroaches as “unhygienic scavengers in human settlements”, squashing them can spread bacteria into the environment that can lead to asthma, allergies and illnesses.
Cockroaches emerge from their indoor hiding spots at night to seek out food, and while doing so, they sometimes crawl over sleeping humans.
Cockroaches in food can cause second-hand poisoning
If you consume this poison second-hand through a cockroach, you could be in danger. The more so if you consume the entire pest by accident. Keep an eye out for poisoning symptoms such as dizziness, confusion, lack of concentration, and stomach pain.
Can Roaches Live Inside the Refrigerator? Roaches live in warm, moist, and humid places. While the refrigerator is not the most suitable place for a roach to survive, it can live inside the motor of the fridge, only occasionally coming inside to take its food supplies.
With around 12 young in every egg case, a female and her offspring can produce 800 additional cockroaches in just a single year.
You would expect cockroaches to be night sleepers just like humans. But these insects are nocturnal. So, when do they take a much-needed rest? You need to know that roaches have a circadian rhythm, a sleep-wake cycle alternating between inactive/asleep and active/wakeful periods.
Distilled vinegar does not kill or repel roaches, making it completely ineffective. Distilled vinegar will help keep your kitchen clean, giving cockroaches less to snack on. However, roaches can live for months at a time without any food at all, and they will eat almost anything to survive.
Cockroach Bites
They have been recorded to eat human flesh of both the living and the dead, although they are more likely to take a bite of fingernails, eyelashes, feet and hands. The bites may cause irritation, lesions and swelling. Some have suffered from minor wound infections.
Smells that roaches hate: a quickfire summary
Oregano, rosemary, mint, eucalyptus, lemongrass and catnip are great herby options. Citrus oils work brilliantly too.
Cockroaches do not avoid light because it harms them. In fact, it's only because they are unable to hide or evade predators when they are in open sight. For this reason, they will not dare to venture out when the light has been turned on in your home.
The most obvious sign you have a roach problem is actually seeing one. The best time to spot roaches is during the night since they are nocturnal insects. You'll typically see them scatter after you enter a room and turn on a light.
The different body parts, waste, and saliva of cockroaches are allergens for certain individuals. Even dead cockroaches can still cause some allergic reactions. Therefore, it is not advisable to step on a cockroach, as its crushed body parts can trigger some allergies.
Does Killing a Cockroach Attract More? Yes, killing a cockroach can attract more to the area! There is an acid released by cockroaches when they die that can be smelled from a distance and attracts more of them to the area.
A cockroach infestation is a sign that something in your home is attracting them, though, so wipe up spills on the counters or floor when they happen, don't leave dishes or food sitting out, and empty your trash cans daily. Having a daily cleaning routine helps prevent pests by addressing such things.
'Salt doesn't kill cockroaches!
That's right, it doesn't. It repels them.
Studies have found a boric acid and sugar combination to be a very effective killer of roaches, but more readily available is Borax mixed with sugar, which also gets the job done. Simply mix three parts Borax to one part sugar for bait, and be sure to keep your pets out of the vicinity.
