Cockroaches live in colonies and will reproduce rapidly, producing hundreds of offspring in a single year. Their eggs have a short lifespan and can quickly reproduce to continue the population. However, these insects can be hazardous to human health. Their secretions can stain surfaces, taint food, and have a noticeable odor.
Fortunately, they’re easy to remove once you’ve noticed their presence. They’re not necessarily a sign of a filthy home – in fact, you can take steps to prevent a cockroach infestation by sealing up cracks and crevices.
Cockroaches are nocturnal creatures that rarely venture out of their hiding spots during the day. In an early infestation, you may not even notice them. But if you do notice one or two, it’s always a good idea to record the details. Cockroaches produce a pheromone that attracts other insects. While they can live in individual clusters, they usually travel in groups when searching for a new nest.
Female cockroaches can lay up to two egg cases each week. Each case contains up to 40 eggs and hatches after about 100 days. Cockroaches also store sperm inside the egg cases. While house roaches don’t make noise, their noises will become more noticeable once an infestation occurs. In the wild, cockroaches only make chirping noises during mating, courting, or defending.
