"Termites are extremely destructive pests that can literally eat an entire home made of wood down to the last speck. Popular wood fences such as redwood, fir, pine, and cedar are all susceptible to termite infestation. You can rid yourself of a termite problem by hiring a professional exterminator, but you may choose to do the job yourself by pouring or painting your wood fence with borax, a much less toxic insecticide option. If worse comes to worst and you'll need to replace your entire wood fence, don't worry. Fort Collins fence professionals like Altitude Fence and Deck can replace your wood fence in no time at all."
