Bagworms can be quite a nuisance in the garden, especially if they build their webby caterpillars bags on your favorite plants. For the avid gardener, the best insecticide for bagworms is one you can use to get rid of this pesky pest without harming your plants or yourself. Bagworms are a common garden pest that consume the leaves and shoots of plants, sometimes stripping them of vital nutrients. They weave pieces of plants, twigs and even dirt into protective foliage that often ends up as a dome or cluster on tree branches, fences and other plants. These uninviting nests can cause damage to or disfigure even the thickest of tree branches. Contact your local county Extension office for guidance on specific insecticides for bagworms in your area. Once you identify the pests, contact your local extension office for guidance on specific insecticide treatments to use.

Best Insecticide For Bagworms

Introduction

Bagworms are a nasty pest, and they can wreak havoc on your garden. There are a few different insecticides that you can use to get rid of them, but some work better than others. In order to be effective, they need to be used while the worms are still young and before they create their bags.

Insecticidal Soap

Insecticidal soap is a biodegradable insecticide that’s safe to use around pets and children, as well as being nontoxic to humans, birds and bees. It works by penetrating the exoskeleton of pests such as bagworms and dehydrating them. The soap should be applied directly to the bagworm larva with a spray bottle, or you can make a homemade solution using one part insecticidal soap to one pint of water.

Neem Oil

Neem oil is an insecticide that can be used to kill bagworms on trees. It is a contact insecticide, meaning it must come into direct contact with the bagworm for it to work. Neem oil is also a repellent and has fungicidal properties, so as long as you apply it correctly, neem oil may help get rid of some or all of your bagworm infestation.

Neem oil works quickly and effectively against most insects, but there are some exceptions:

• Termites. Termites do not die from the application of neem oil because they eat wood pulp instead of leaves from plants; therefore, termites are not likely to be affected by this treatment method for bagworms (but if you have other types of insects such as ants or roaches in your home – then neem could be useful).
• Moths/butterflies/bees/wasps. These creatures tend not to be bothered by neem at all; however they may avoid areas where they detect its odor so try placing small amounts around doorways or entry points if these pests bother you regularly!

Spinosad

Spinosad is a biological insecticide, derived from a naturally occurring soil bacterium. Spinosad is considered an organic insecticide and can be used in organic gardening.

Spinosad was discovered in 1979 by Dr. John Sankey, who worked for the USDA Agricultural Research Service Center at Fort Detrick (Frederick, Md.) and first registered it with the EPA in 1995 as an approved insecticide for use against certain caterpillars including bagworms.

Bacillus thuringiensis

Bacillus thuringiensis is a bacteria that kills caterpillars. Bacillus thuringiensis is sold in liquid or powder form, and is safe for humans, pets and birds. However, bacillus thuringiensis may not be effective against bagworms if the caterpillar has already formed a cocoon to protect itself from predators (in this case, kill the bagworm eggs with insecticides).

Malathion

Malathion is a synthetic organophosphate insecticide that controls insects on fruits, vegetables, ornamentals, and cotton. It is used as a contact insecticide and works by paralyzing the nervous systems of target pests.

Imidacloprid

Imidacloprid is a systemic insecticide that can be used to control bagworms. It works by stopping the activity of certain neurotransmitters in insects and arachnids, which in turn disrupts their nervous system and causes them to die.

Imidacloprid is a neonicotinoid pesticide, meaning it’s derived from nicotine but modified to have insecticidal properties. The compound is absorbed and distributed throughout the plant as it grows, so you don’t need to worry about missing any eggs or larvae when spraying your plants with imidacloprid insecticide.

Pick an insecticide and get out there to kill those bagworms!

Now that you know what a bagworm is and how to identify it, it’s time to get out there and conquer these pests. There are several insecticides that can be used to kill these little guys, but not all of them will work for every situation. You can use the following method if you have only one or two bagworms:

• Apply an insecticide directly on the larvae with a sprayer or brush applicator

If this method doesn’t work (or if your tree has more than three infestation sites), then it’s time to try something else! For larger infestations, apply an insecticide directly on all members of the colony, which includes both eggs and larvae. The easiest way to do this is by drilling holes in a layer of cardboard below where you want your product sprayed (soil). Then add water until it runs out of those holes; this should be enough liquid for your sprayer bottle (if not—add more!). Now just pour some chemical into each hole until they’re full; leave them alone for about six hours before removing them from underneath your tree’s leaves

Conclusion

We’ve covered the best insecticides for bagworms, and we hope our recommendations help you make an informed decision when it comes to tackling your bagworm problem. As always, remember that safety should be a top priority: make sure to follow the directions on any product you end up using and store it properly when not in use. If this is your first time applying an insecticide to deal with a pest problem, consider opting for one of the lower-toxicity products here (such as neem oil or spinosad) before moving onto more toxic options like malathion or imidacloprid. We also suggest that you research which types of bagworms are most common in your area; if they’re less likely to cause damage than other species, you might want to think twice about using an insecticide since there are more eco-friendly ways to get rid of them.
