The Mole Patrol was founded in 1983 by Kelli Larsen. For many years it was the only pest control company in the Pacific Northwest dedicated to exterminating just moles and Kelli became the best mole exterminator in the business receiving both local and national recognition. The ownership changed in 2003, but the focus remained unchanged - do one thing, moles and be the best in the business of exterminating them. Since then, through extensive research and careful analysis of what works and what doesn't work, we have taken mole extermination to its highest level.
The truth is we really don't know. The amount of mole activity is not a good indicator of the number of moles. Add on variables like: the time of the year, size and location of your property, whether your property is bordered by woods and/or wetlands, does your landscaping design incorporate automated sprinkler systems and large areas of flower beds; the possibilities become endless. However, moles are generally solitary by nature and will aggressively defend their burrow systems. Many sources suggest one acre will only support five or six moles.
