Randy from Nature's First Pest Control really knows his stuff. I called him to help with rodent problems in my mom's garage. He met us there, bringing Brent to help. They did a thorough search for every possible mouse entry, then fixed these, leaving the mice only one way out; that's where he said we'd catch them. He was able to ascertain that there were not other rodents involved, only mice. He taught us all in the ways of mice and how to properly set the traps. Within an hour or so of his leaving we'd already caught 4 mice. He told us what to expect as far as how long it take for all the mice to be gone and we're right on track and well on our way to complete eradication. What a relief. Randy is extremely knowledgeable and he was very patient with all the questions we asked. He guarantees his work and invited us to call with any questions. I'd recommend Nature's First Pest Control 100 and will certainly call them again if the need arises.
