The answer to 'rat invasion' is that a rat infestation is a common problem for many homeowners. Rats can enter homes through small openings and breed rapidly, leading to a full-blown invasion. Common signs of a rat problem include seeing droppings, hearing noises in the walls or attic, and damage to food packaging or wiring.
To address a rat invasion, it's important to first identify and seal any entry points, remove food sources, and use traps or baits to eliminate the existing rats. However, for a severe or persistent infestation, it's best to call in a professional pest control technician who can provide more comprehensive solutions and prevent the problem from recurring.
