Have you contacted the Washington State Dept. of Agriculture?

Spider mites don't produce honeydew. Nor do they produce bites.

Commercial growers can get help from their county's Extension Service agents, perhaps the Small Farms agent.

Find your county's office using this map - http://npic.orst.edu/pest/countyext.htm

I applied Azamax on the advice of a Washington State University professor of agriculture. Spider mites definitely bite, although you may be thinking of chewing holes in leaves instead of what I meant. They bite and suck juices out of leaves and exterior of squashes, leaving pockmarks and sticky . It's unmistakable that they are spider mites since there are copious webbing and billions of them.

The "honeydew" may just be the squashes natural reaction of weeping at a point of injury.
