Cockroaches can wreak havoc on your home. To win the war against cockroaches, here’s what you should know that Cockroaches can enter your home in many different ways, from the outside through cracks and crevices, vents, sewer and drain pipes, even in grocery bags. Your home is an ideal breeding ground. With plenty of food, warmth, water and nesting sites, they can remain active all year round.Cockroaches reproduce quickly. For every one you see there can be 200 more hiding and multiplying behind your walls.Because cockroaches are nocturnal, if you’ve seen one, you haven’t seen them all. The few cockroaches you see by day were likely forced out by overcrowding; a possible sign of severe infestation. The dust created by cast-off cockroach skins, dead bodies and droppings can aggravate allergies, especially in sensitive individuals. Cockroaches are better at hiding than you are at finding them, and their eggs are naturally protected from insecticides. Without special equipment, materials and know-how, it can be a losing battle.
