Just the neighborhood block within which you reside is your little island. The home in which you live is your castle. The problem is that both home and island are subjected to (at least) seasonal invasions. It is perennially worse if the climate of your neighborhood, or area, is particularly hot and humid throughout the year. And because there is this little island, you must be surrounded by water, all metaphorically speaking, of course.
Whether it is a small brook or open canal, a rivulet or free-flowing river, a dam or even a lake, it is a favorite breeding ground for the mosquito. To think that mosquitoes will migrate from one continent to another, across the ocean water to establish a breeding ground is mindboggling, if it were not tragic. It is tragic because these pests are dangerous. They bring with them diseases, as dangerous as the infamous malaria.
Within your little castle, on your little island, you may be feeling hapless to do anything about this. Indeed, this is not something that can be tackled by an excursion to the supermarket or hardware store. It is not something that can be managed with a DIY project over the weekend. It is an expedition of force that can only be effectively managed by the mosquito control staten island patrol or project.
These are your expert terminators. They need to be fully on board throughout the year to make sure that their exterminatory effects take full effect, keeping the deadly mosquitoes at bay throughout the year, so much so that the determined hordes must find breeding grounds elsewhere, preferably hundreds of miles from where your little castle and island is situated. From this moment on, may there be no further influx of mosquitoes.
