Preventing Army Worm Infestations

Preventing an armyworm infestation is vital to maintaining a healthy lawn and garden. Here are some cultural practices and chemical prevention methods to keep these pests at bay.

Cultural Practices

Proper lawn care practices can help prevent an army worm infestation. Here are some tips:

Mow your lawn regularly and keep it at the recommended height for your grass type. Taller grass can help shade the soil and prevent egg-laying.

Water your lawn deeply and infrequently. This encourages deeper root growth and makes it harder for armyworms to feed on the grass.

Remove thatch and other debris from your lawn, as this can provide a hiding place for armyworms.

Inspect new plants and sod for armyworms before planting.

Rotate your crops in the garden to prevent armyworms and other pests from building up in the soil. (Learn How To Harvest Chives Without Killing The Plant)
