When do Bagworms hatch? (Quick Answer!)

Different worms hatch in different periods, and their feeding relationship, adaptations, and colors are almost unique. Other worms hatch their eggs in different seasons and places.

However, today I would like to talk about the tiny organism, which is considered a native defoliator and commonly found in the Northside of the United States.

As there are many different worms, people become confused about when to kill or remove Bagworms. I will talk about when when do Bagworms hatch?

Bagworms generally hatch their eggs in late May and at the beginning of June and July. They love to give birth in the summer season. There are some stages of the lifecycle of the Bagworms which are pretty similar to other worms.

In this garden gild guides we’ll discuss the following:

  • What month do you spray for Bagworms?
  • What do newly hatched bagworms look like?
  • How did I get bagworms?
  • When should I treat Bagworms?
  • Will Bagworms come back every year?

What month do you spray for Bagworms?

As you know, Bagworms show up and bring their new generation in late May and at the beginning of June and also July, and it is the favorite time of these tiny adorable, clever creatures. So the best month for spraying Bagworms is June!

It will be very effective if you plan to remove Bagworms near your house or in any other area. But suppose you are a newbie about the camouflage nature of the Bagworms.

In that case, you will not recognize the difference between Bagworms, eggs and pine cones, or other plant structures because they look pretty similar.

There are some easy ways to understand when the eggs of Bagworms will hatch. Do not spray unnecessarily, and it will be a good idea to wait until a couple of trees, and Japanese tree lilacs begin to raise their heads.

Because at this time, all the female Bagworms start the journey to hatch their eggs.

You can use some of the spray, such as Bacillus thuringiensis, spinosad, insecticides, or pyrethroid sprays that are ideal for removing or killing Bagworms and their babies.

But if the larvae start to grow, at that time, insecticides will not be more effective. So you need to use spray or chemicals in time.

What do newly hatched bagworms look like?

Newly hatched Bagworms are very tiny, and you can barely see them. As I have said before, some of you might get confused when you see them.

When they are at the very first stage, you can not see them if you do not have an idea about them.

After some days, you will notice these tiny pine cones like eggs turn into black pigmented or tan-colored larvae like a small spindle-shaped bag. 

Finally, you will be able to see worms that have a 1.5 or 2 inches short (3.9 to 5 cm long) slightly slim body hung on the trees, twigs, or various kinds of shrubs or branches.

How did I get bagworms?

In jungle-type areas, bagworms are geographically found in Eastern United States, South Africa, Croatia, and North East Iran.

But bagworms can be found in general—for example, your house. If you have cedar trees, juniper trees, pine, spruce, arborvitae trees around your home, there can be a possibility for the Bagworms to be found.

Like if the temperature of your country is high, moist, or humid, and there are stucco walls, cobwebs around your location- you will find more Bagworms and eggs.

When should I treat Bagworms?

You know Bagworms reproduce in the summer season, generally, two months, May and June, when the temperature and humidity are high. They love to stay in moist environmental conditions.

When should I treat Bagworms?

After reproduction, they need time to grow in the spring season and start anew. Then, these tiny Bagworms will begin to reproduce or hatch their eggs in the following spring season. So it is a continuous process.

The best time for treating Bagworms is the time between May and June. First, you need to know the arrival time of the blackworms.

There are some ways you can get rid of Bagworms. They are:

  • One of the easiest methods to remove or kill Bagworms eggs in warm water and liquid detergents or soap. You need to cut or remove the egg sacks using sharp objects such as sharpened knives. Do not touch the egg sack with bare hands. Make sure that these egg sacks have fallen into the soapy water because this watery substance will suffocate the eggs and eventually die.
  • You can damp these wet egg sacks into the plastic bags and leave them in a waste bin.
  • For better results, you need to do this again and again in the winter and spring season, which will reduce the chance of the growth of the Bagworms egg.
  • Egg sacks of the Bagworms can be challenging to find because it is pretty the same as the pinecone. It would help if you kept your eyes open unless you could kill some of the Bagworms, which may come again. Always check the dead pine needles and branches of the trees which Bagworms prefer to live and hatch.
  • The wind can fly their silk. If any silk gets attached to the garden or trees, they may start to grow. For this reason, you need to sweep the areas if you doubt that there can be a chance of the Bagworms to reproduce or thrive.

Will Bagworms come back every year?

According to the experts, it is found that the Bagworms will come once a year. In winter, they lay eggs and come out from the eggs in spring. After that, these eggs start to grow.

So I think there is no chance that the bagworms come more than one time a year. But some of the larvae shells and silk may remain where they were hatched.
