To fight cockroaches at home, prevention is the key

Often, the presence of cockroaches is associated with imperfections in the drainage system of buildings. That’s where cockroaches live and proliferate. The presence of an old sewer system or obsolete fittings and pipes can also become a way of passage between the sewers and the home.

Find the presence of cockroaches. Look in the bathroom, the shower, and near areas. Try to discover the habitat chosen by the insect that can also nest anywhere else in the house.

How to fight cockroaches in the kitchen

Generally, the places chosen by cockroaches are usually warm and welcoming, where there is food and water. Therefore, the kitchen is one of the best places where they can access, although they can also nest in cracks in the pavement, wall coverings, cracks in the wood, drainage boxes, false ceilings …

To combat cockroaches in the kitchen, check the food and make sure there are no traces of what they can eat. Remove cardboard boxes because they can be a source of heat and become a “healthy” environment for the insect. In the kitchen, the presence of ovens or appliances that generate heat and the remains of food can attract the unwanted guest.

Clean the grease from the kitchen and look for cracks there and in the rest of the house. Bread crumbs and leftovers can attract insects. Store food carefully in the cupboards and keep it clean. Avoid condensation and water leaks so that insects do not appear.

Prevention is better than cure. Therefore, seek professional help when the infestation problem is there, and it is serious. The experts will disinfect your house and give you useful tips to keep the place free of cockroaches.
