Bagworms are caterpillars that spin protective sacks and the leaves, twigs and bark of their host plants. The brown, teardrop-shaped bags reach 1- to 2-inches long and generally seem like seedpods or small robes. These voracious eaters can defoliate host plants, causing them to weaken, seem unattractive and even die. Without releasing compounds into the 15, several organic treatments exist to treat bagworm people.
Bagworms (Thyridopteryx ephemeraeformis) will feed on about 130 plant species, but their favourite foods will be the junipers (Juniperus spp.) , such as red cedars and Leyland cypress trees, which grow in U.S. Department of Agriculture plant hardiness zones 2 through 9 and zones 6 through 9, respectively. Bagworm men are fuzzy moths using wingspans, but the mature females are flightless, worm-like animals that reach about 1 inch in length and never leave their bags. They set between 500 and 1,000 eggs before perishing inside of the bags. The blackish caterpillars emerge, and the eggs hatch once warm weather arrives at the spring and start feeding on their host plants.
You can typically control localized or small bagworm inhabitants by handpicking and ruining the bags, however you must do this no later than early spring to prevent the eggs from hatching. Dip the bags into a pail of soapy water instead of simply letting them drop to the floor. This guarantees that the caterpillars don’t return for their host plants. After you eliminate the sacks, cut the lace bands which attach the bags. This silk can girdle limbs and cause branch dieback in only a few decades, if you don’t.
Bring Natural Enemies
Bagworms have loads including wasps and birds. Bring the predatory beneficial insects by planting daisy and aster family members. Shasta daisies (Leucanthemum X superbum) and Frikart’s asters (Aster x frikartii) both work as attractants while incorporating pops of colour in yards throughout USDA zones 5 through 9. Feeders, Putting birdbaths and birdhouses near trees helps attract birds which will feed on the caterpillars.
Spray With Btk
Control youthful bagworms by using a pesticide containing Bacillus thuringiensis var. Kurstaki (Btk), a natural soil bacterium which makes caterpillars stop feeding and die within just a few days. Once the bags are still smaller than 1/2-inch long, you must start spraying Btk in your plants and the larvae are feeding, generally from May through the end of June. Carefully read and follow the application and mixing directions on the item’s tag. 1 pesticide advocates mixing 4 tsp of product for every 1 gallon of water. With a handheld garden sprayer, thoroughly saturate all leaves surfaces, including the tops and undersides of leaves. Until you achieve control, repeat applications.
Spinosad is a pesticide created from soilborne bacteria. It toxins caterpillars that eat or touch it killing bagworms. Follow the directions on the tag of the manufacturer since instructions will be different. 1 product advocates mixing 4 tablespoons of product for every 1 gallon of water at a handheld sprayer. Spray the tree until you cover the tops and bottom surfaces of the foliage of the host plant. In case bagworm inhabitants persist, apply spinosad solution in seven to 14 days.
A Word of Warning
Spinosad is toxic to honeybees for about three hours after application. Spray in the early morning or late evening to avoid damaging the insects. Btk – or spinosad-based products. Pesticide after a heavy rain. Even these organic ingredients can cause skin or eye irritation although spinosad and Btk offer bagworm control. Protect yourself from exposure by wearing goggles, a facemask shoes with socks, long sleeves and shorts. Maintain out family and pets of the treatment area before the spray dries.
