I have purchased a home in Virginia that was built in the 50s. There was carpet over the original hardwood floors. I have pulled up the carpet and am pulling staples and tackstrips before refinishing the floors. My question is about the fairly large gap that is between the baseboard trim and the floors. I'm planning on installing quarter round to hide this gap, but I'm wondering if I should fill this gap with caulk first. It seems it would behoove me too because the gap would potentially create a good place for bugs and other small pest to hide and travel through the house. The house is rural so insects could be a problem. Termites are a problem in this part of the country. Thanks for your time and input.
