I am a big believer in ERVs. Condition the house and an ERV allows ventilation without pulling in humidity.

In central Oklahoma, where I live, May and June have oppressive humidity. The below suggestions allow me to keep house humidity below 55%.

A good dehumidifier can lower humidity, but watch out for dryers in the conditioned space. They suck out 300-600 ft3 per minute. That will evacuate a house of conditioned inside air with just one dryer run.

1) Button up house (to reduce air infiltration)
2) use a good dehumidifier or properly sized AC unit) - or both
3) install ERV that runs at low speed (20-40 ft3/min) all the time
