Pheromones. Many insects use pheromones to leave markers where food is located or to lay down a path to food. You usually see this trait in social insects like ants and other very successful insect species. When I say successful, I mean abundant. Ants are abundant worldwide, as are most social insects like bees, termites, and some wasp species. Another group of insects which are not actually social like the bees in a hive, but come together all the same. Is that of the cockroach. Many species of cockroach are known to aggregate. Once the presence food is announced, they generally appear. Aggregation is the term that describes when individuals form together into a group or cluster. To use an analogy, it’s like if you were to post a “FREE BEER” sign in the center of a college campus. One student would show up and then tell his friends. Soon enough many would all start coming in droves out of the woodwork. Like the college student with the promise of free beer, cockroaches too will come together drawn towards the promise of free food.
Sometimes just one species, sometimes many different ones. You may see generations of the same ones, or they may appear all at once. Depending on the species you will see different forms of aggregation. A very strong example of this is the German Cockroach, who are well known to aggregate as well as using pheromones. Insects that use pheromones to advertise food to other individuals of their same species are generally very successful. This is even more true for the German cockroach, who is not a social insect, but when aggregate together gains many of the same benefits of those that are social. These benefits range from protection in numbers from predators; an individual is less likely to be eaten in a large group; to that of ease in finding a mate.
The last one is the real issue with German cockroaches, you don’t want them to find a mate. They can reach explosive population growth starting at very low numbers. Their ability to reproduce and mature is insanely fast even by cockroach standards and is absolutely terrifying by human standards. So having a bunch in a large group, spells disaster for any unlucky homeowner as they soon will see their home become a giant breeding ground, starting just from a handful of these little guys (and I do mean little).Tags: ants, centipedes, cockroaches, commercial pest control, earwigs, eco-friendly, fleas, Fort MIll SC, hornets, millipedes, mosquito control, mosquitoes, pest, pest control, pest control fort mill sc, pest control rock hill sc, residential pest control, Rock HIll SC, rodent control, rodents, silverfish, spiders, Tega Cay, ticks, wasps
