How To Get Rid Of Pickleworms

We have found some easiest and most environmentally friendly solutions to free your garden from pickleworms. Let’s discuss some organic and inorganic methods to eliminate these destructive moths and save your vegetation.

1.     Handpicking

Handpicking can be effective if the infestation is on a small scale. You need to examine the garden for these moths and their eggs closely. Don’t forget to dispose of the larva and eggs in soapy water. This method can be effective if you monitor your garden regularly and be consistent with removing pickleworms by hand.

2.     Fruit bagging

Fruit bagging is another organic way to get rid of pickleworms. It is the practice of covering fruits with plastic bags to protect them from pests. This method can be time-consuming if you have to deal with many plants and fruits. However, it is crop friendly and a part of organic farming. It is best to use paper bags to let plants breathe easily.

3.     Sampling

Insect sampling is sometimes known as scouting or monitoring, which involves using traps to collect the insects. Sampling pickleworms can be tedious as they are nocturnal and are not attracted to light traps. However, you can use pheromone traps to trap these insects.

4.     Natural predators

The use of natural predators is one of the best ways to get rid of pickleworms. The natural enemies of this larva include Calosoma beetles, soldier beetle, Harpalus beetles, red imported fire ant, Trichogramma wasps. You can use these natural predators in your garden to control pickleworms.

5.     Resistant varieties

The resistance to pickleworm is based on various plant varieties, including Summer Crookneck, Early Prolific Straightneck, Butternut 23, and Early Yellow Summer Crookneck. You can use these varieties to keep this insect at bay. However, plants like Benning’s Green Tint Scallop squash, Cozini Zucchini, Black Caserta Zucchini are more prone to pickleworm attacks, so avoid planting them in your garden.

6.     Row Covers

A floating row cover shields the plants from pickleworms, melonworms, and other insects, such as whiteflies and aphids. As pickleworms are nocturnal, cover your plants with floating row covers only at night.

In the morning, this moth is inactive so remove the cover allowing the bees to pollinate. Also, replace covers in the late afternoon to keep away nocturnal moths from laying their eggs.

7.     Throwing Damaged Plant

If you notice a plant in your garden that is highly infested by pickleworms, we suggest uprooting it and discarding it. Such a plant threatens your garden as worms can easily reproduce in the soil. Discard carefully in soapy water so the moths are killed and unable to return.

8.     Use Insecticide

A spray of pickleworms designed insecticides on the infested plant will help you get rid of them.

When selecting an insecticide for edible plants, look for products that are labeled for use on the specific crop you are growing and that mention the target pest (such as pickle worms) on the product label. Follow the instructions provided by the manufacturer carefully, including application rates, timing, and any necessary safety precautions.

In this regard, Diatomaceous earth (DE) is considered the best natural insecticide:
