To address a mouse infestation, set traps and seal any potential entry points such as gaps around windows and doors. Keeping your home clean and free of food debris will also deter them from settling in.

3. Spiders

While most spiders in Ottawa are harmless, their webs and presence can be unsettling for many people. Some species may also bite if provoked, causing mild reactions.
