Usually bringing in some pest control experts to do a quick screening of your house is an effective way to determine if monthly pest control is needed for your home. They’ll get into the darkest and deepest corners to be sure of your property's pest density. This is important because there are several kinds of pests that are so small and so unknown that you may never know if they’re actually there.
Like we said earlier, the types of pests you need to spray for and how frequently you need to do it largely depends on the location of your property. If it is affected by common pests such as cockroaches and termites, then a bi-monthly spraying might take care of the problem. However if you live in an area where ants are a common infestation, then a monthly service might be necessary.
The best way to determine if you need monthly pest control or not is to call a pest control service, pick their brain, and get them to come out and take a look.
