Rats can be quite tough to deal with if they gain entry into your home, and worse still, your bedroom. They create annoying scratchy and squeaky noises, and they're extremely good at keeping out of sight, coming out mostly at night. A single rat could be a menace in a bedroom since they multiply quickly and you will soon have a nest of rats in your area should you not act fast.
Out of the many rat removal methods on the market, the only one that would put a stop to your rat problem is to identify its entrance holes and block them. Without this vital step, every exercise in ridding your home or room of rats are a temporary fix.
Places to check include walls, vents, under big furniture, behind wall fixtures, roofs, soffits, and everywhere there's a hole. Every hole, however small, is a potential entry point.
Leaving the door open won't work for rats as they're extremely comfortable nesting in human spaces. Anyway, it would just go into a different area. The way to eliminate the unwanted visitor is to trap it.
One-way exclusion funnel: All identified rat entrance holes should have been sealed off except one (and it should lead outside) before setting this up. Put the funnel on the one remaining entry point and carefully fix it on the mouth of the opening. When the rat goes out through it, it would be not able to return inside. After successfully removing the rodents, then proceed to seal off this one staying opening to avoid any re-entry.
Glue Trap: It is made up of a very strong adhesive to which rats become stuck by their paws whenever they try to walk over it. It has to be checked often so the rat doesn't remain stuck to the glue trap for hours, days or even weeks, finally dying inhumanely of thirst and hunger.
