Spraying with 6 pounds of dry lead arsenate to 100 gallons of water is effective, but three applications (about June 22, July 10 and July 28) are necessary because of the long hatching period of the insect. One thorough application, about August 6, of the nicotine sulfate and soap spray advocated for the black-headed fireworm will eradicate this Spotted Fireworm. Fig. 20. Cranberry uprights with tips webbed by young worms. Spotted Fireworm.'^ This is the least important of our four fireworms.

It sometimes does considerable injury but never browns a bog. Distribution and Food Plants.
