These traps will not eliminate a raging infestation of aphids or whiteflies, but the traps do indicate when the first few specimens show up so that control measures can be undertaken quickly. Trap crops involve planting a crop that is very attractive to the pest, but not essential to the gardener or landscaper. Some of the pests and treatments listed are not from research-based pesticide labels but are from information given in catalogs or other sources and thus should not be considered recommendations by the North Carolina Cooperative Extension Service. Boiling water can be poured on ant hills to kill the ants inside. A beer can may be used as a bait for slugs.
Slugs crawl in and drown during the night.
Slugs can also be trapped by placing boards in the garden in the evening and destroying the slugs beneath the following morning. Diatomaceous earth is labeled for insect and mite management, but when used at rates high enough for successful control, there is excessive residue. In addition, the user is subjected to a considerable respiratory hazard. Millipedes and wireworms can be trapped by burying a juice can that has been punched with holes and filled with carrot or potato peelings in the landscape. The trap should be emptied each week and pests should be destroyed.
