I heard they hide out in bushes during the night. Spray Sevin in the holes and seal with putty. Painting wood with enamel paint or oil-based varnish or shellac may stop them. Fusiform rust on pines makes large cankers or swellings that turn yellow in spring as they release spores. There is no effective spray for this.
Infected trees are prone to break.
Cut out cankers on limbs and remove trees with main trunks infected. Shortleaf pine is somewhat resistant. Fortunately, there are resistant varieties. Look for these varieties which are listed by flower color and height. Whiteflies come out as temperatures climb.
