I would leave it untarped for the summer to dry out then tarp it come fall. Isn’t there an insecticide you can look into for treating the vicinity for ants and termites. Also spiders 
Just an issue of time to get to it. Life's been quite busy lately. Will likely work at it in batches but like I said I have 3, 100 ft trees coming down. Going to be quite a bit of wood.All wood, once dry, put out about the same amount of heat per pound and since locust is quite dense the heat per volume is very good. However, it will not dry much left in logs. It would take several years to dry enough to burn up to its potential. Why not cut it to length and split and stack it on the pallets where it is laying?
