Why Are Woolly Bear Caterpillars Pests?
Wooly bears are mostly harmless to humans as they don’t bite and are non-toxic. However, the bristles in their bodies can cause severe irritation to the human skin.
Adding to that, they actively eat the leaves of flowering plants, leaving big holes in them. This affects the aesthetic value of your flowering garden and can also be dangerous for the plants.
They also infest other useful leafy vegetables like spinach and cabbage.
Due to these reasons, wooly bears are considered as pests, no matter how cute they look from afar or how well they predict the weather!
How To Get Rid of Them Naturally?
As mentioned above, these fuzzy caterpillars can be a big problem for your garden. Therefore you need to take proper measures to eliminate them.
It is good to use natural ways to get rid of them, as chemicals and insecticides can affect the fertility of the soil and also kill other beneficial insects.
Here are a few tricks that you can use to get rid of caterpillar infestations naturally.
Use a mixture of pepper and garlic
A mixture of pepper and garlic can be used in a homemade spray to remove the woolly bears. Dissolve the pepper-garlic mixture in some water and put it in a sprayer.
Once that is done, sprinkle it directly into the worms, and as the liquid gets absorbed in their bodies, it will slowly kill them.
You can also spray it on plants and trees to keep these pests away.
Use Vinegar
Most caterpillars don’t like the smell of vinegar. Therefore you can sprinkle a few drops of it in areas where you notice regular caterpillar activity.
This will drive them away from those spots, and they might look for other nearby plants to infest. You can also keep some decoy plants that are non-flowering so that they can move to those instead.
Remove logs and debris
During the winter, these caterpillars come to your yard in search of a warm spot to hibernate.
Unattended logs and debris are the perfect spots for them to live. This is why you must keep your yard clean and don’t leave debris unattended.
Invite birds to your yard
Birds are one of the topmost predators of wooly bear caterpillars; therefore, having regular visits from them will be beneficial for you.
To attract these birds to your garden, you just need to find the right feeding seeds and sprinkle them in the yard, and they will finish the majority of caterpillars from the spot.
Use a worm barrier
Worm barriers are tough piece of cloth that is wrapped entirely around a plant to keep it safe from pests.
These are ideal for keeping flying insects like moths away from plants. Since wooly bears the larval form of tiger moths, the barrier will restrict the adult moths from laying eggs in the plant.
This will keep it safe.
Other Methods to Remove Them
Before using any insecticides to get rid of woolly bear caterpillars, make sure that they are not harmful to other beneficial insects.
Mentioned below are two safe chemical methods that you can use to get rid of wooly bear caterpillars from your garden:
Pheromone traps
As the name suggests, these traps use pheromones to lure insects. Here, once the insects fly to the trap, they get stuck on a sticky surface.
Put it in areas where tiger moths usually show up to lay eggs, and if you kill the tiger moths, they won’t be able to lay the eggs.
Bacillus Thuringiensis Berliner
The Bacillus Thuringiensis Berliner is a bacteria that is highly effective in killing wooly bears.
The good news is that this bacteria doesn’t cause any harm to plants and is environmentally safe to use.
It is also an active ingredient in many of the insecticides that help to control pests from damaging useful plants.
How To Prevent Them From Infesting Your Plants?
Here are a few useful ways to them these species of caterpillars away from plants:
- Make a homemade pepper spray using peppers, onion, garlic, and water. Dissolve it properly and spray it on the plants to keep these pests away.
- Catch the caterpillar crawling in your garden with a glove and put them in a bucket full of lukewarm soapy water; this will kill these pests instantly. Throw away the dead caterpillars from the solution and repeat the process.
- Have plants like cilantro, aster, basil, yarrow, and more in your garden. The aromatic smell of these plants will drive the pests away.
