NOVELTY - Device (10) comprises: a partially enclosed hollow container comprising an orifice sufficiently large to allow the insect to enter the container; and an insect attractant layer comprising an insect attractant deposited within the container. The container is configured to capture and kill the insect such that the killed insect is deposited above or within the insect attractant layer and further the insect attractant layer comprises an aquatic biomass material.    USE - The device is useful: for attracting insects comprising subclass Pterygota, fly, black flies, cluster flies, crane flies, deer flies, face flies, flesh flies, green flies, horn flies, horse flies, house flies, sand flies, sparaerocierid flies, yellow flies, western cherry fruit flies, tsetse flies, cecid flies, phorid flies, sciarid flies, stable flies, mites or gnats; for suppressing a population at least one species of insect in a defined area; for the production of flies or maggots, where the device is configured to allow the growth of maggots (all claimed); and to suppress insect population in farmland, horse pastures, poultry pastures, grazing and non grazing livestock ranch, slaughterhouses, meat and fish processors, dairy farms, hog farms, beaches, restaurants, homes, boats, recreational park areas, produce farms, hospitals, landfills, mushroom farms, waste management facilities or composting, where the waste material after deployment is used as fertilizer, food or an animal comprising bird or fish. Test details are described but no results given.    ADVANTAGE - The device: utilizes attractant, which does not comprise a synthetic insecticide; and is configured to prevent the detectable growth of maggots in the device. The array or the device is capable of suppressing the population of at least one species of insect of an area greater than 0.1, 0.3, 0.5, 0.7, 1, 1.5, 2, 3, 5, 7 or 10 acres, where the suppressing of population is determined by the number of insects captured or killed 6 days after deployment of the trap or the array and the number of insects captured or killed is at least 3000, 5000, 10000, 20000 or 50000 insects, fewer than 0.5% of insects that enter the container exit the container; does not suppress grasshopper, bees, and butterfly populations (all claimed), hence exhibits selectivity in attracting, killing or suppressing insect population of at least one insect species; suppresses the emergence of maggots from the trapped flies in the deployed traps, where the suppression of fly egg development/elimination of maggots reduces the risk of insect resistance to the attractants; can be synthesized inexpensively from organic materials; and has very low toxicity to humans and animals (horse, cattle birds, chicken etc) when deployed and low environmental toxicity of the waste products after deployment.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) an array of insect traps comprising many insect traps positioned in proximity to each other, where the array comprises at least two traps cluster in an area of less than 100 square feet;    (2) a composition comprising processed biomass, fluorescent dye and particulate matter; and    (3) a fertilizer comprising the captured flies.
