Caterpillars, or larvae, hatch from the eggs in early spring about the time the leaves on their host plants emerge. Within a few days, eastern and western tent caterpillars feed on these new leaves. Tent caterpillars form small webs and enlarge them as they grow.
Should I kill tent caterpillars?
Sometimes getting rid of tent caterpillars means killing them. While small infestations can be taken care of by dropping the nests into soapy water, contact insecticides work best for larger populations. Bacillus thuringiensis (Bt) is the most effective.
Do tent caterpillars turn into butterflies or moths?
Like all butterflies and moths, eastern tent caterpillars undergo complete metamorphosis with four stages: Egg – The female oviposits 200–300 eggs in late spring. Larva – Caterpillars develop in just a few weeks, but remain quiescent in the egg mass until the following spring, when new leaves appear.
What do tent worm caterpillars turn into?
An adult male eastern tent moth. The adult moth emerges from the cocoon about 3 weeks later. The moth is reddish-brown with two pale stripes running diagonally across each forewing. Moths mate and females begin to lay eggs on small branches.
Are tent worms harmful?
Eastern tent caterpillars are not harmful to humans or pets. Tent caterpillars do not do any lasting damage to trees or foliage. These caterpillars use pheromones to mark off trails on host trees.
Can you burn tent caterpillars?
A very common way of destroying tent caterpillar nests is to burn them with a small propane torch. This is the way I learned growing up and I’ve seen many people kill caterpillar nests this way.
What do tent worms look like?
Adult tent caterpillars are brown and yellowish moths with two diagonal markings on the front wings (Fig. 4). Their wingspans are about 1 inch. These moths are attracted to lights.
What eats tent worms?
Songbirds pick the caterpillars off branches and leaves. Robins, blue jays, red-winged blackbirds and cardinals all eat tent caterpillars. When the caterpillars crawl to the ground to pupate, they are also picked off by ground dwelling birds such as wild turkeys.
What are tent caterpillars good for?
Although some people may find them unsightly, in most years tent caterpillars do not cause serious injury to their host plants and can even be beneficial to their environment by providing a food source for wildlife. Typically, tent caterpillars only defoliate a few branches and only actively feed for a few weeks.
Do tent worms turn into gypsy moths?
No, it’s not a gypsy moth, the dreaded invasive creature released in Medford, Massachusetts in the late 1800’s. It’s the Eastern tent caterpillar or Malacosoma americanum (Fabricius, 1793) which are often confused with gypsy moths or bagworms. People really hate tent caterpillars.

How long before tent caterpillars turn into moths?
Late-stage larvae become solitary feed- ers and no longer use the tent. The larvae mature in 30-42 days, depending on weather conditions. Pupation occurs within silken cocoons spun on branches in the remain- ing leaves of host trees, on non-hosts, or in leaf litter. The duration of the pupal stage is from 12-18 days.
How long are tent caterpillars active?
Tent caterpillars will remain active for a few days inside the home so its important to get a good treatment down as soon as possible. If not done early enough, expect to see a lot of adult moths hatching out of pupa cocoons in 1-2 months following the initial invasion.
Do tent worms bite?
Although this univoltine insect is called a tent caterpillar, it is unlike other Malacosoma species in that the larvae do not construct tents. The caterpillars themselves are relatively harmless to people (i.e., they do not bite or sting) although a few people have an allergic reaction to handling them.
Do ladybugs eat tent caterpillars?
Ladybird Beetles Ladybirds will eat other type of insects, notably caterpillars. Since aphids and caterpillars are harmful to plants, gardeners use ladybirds to biologically control them. Caterpillars have fairly soft bodies; ladybirds find them very soft to munch, particularly small ones.
Are tent worms harmful to trees?
The good news is the tent caterpillar is not as damaging to trees and not as annoying to humans as the gypsy moth. Although this damage is unsightly and worrisome, it usually only weakens the tree after three or more years of more than 50% defoliation.
Are tent caterpillars poisonous?
It is important to note, however that, while not poisonous, the guard hairs found on the Eastern Tent Caterpillar are irritants to the stomach lining of many animals including horses. Eastern Tent Caterpillar are extremely sensitive to temperature which serves them well as a species that feeds on fresh, spring leaves.
