Backfill the holes with soil and mark their locations with sticks. Before planting your potatoes, dig up the traps and pop any wireworm you find onto a bird table.

In arable rotations, cultivation has the greatest effect on reducing wireworm numbers, physically killing larvae and leaving them exposed to predation. Ideally, land earmarked for potatoes should be ploughed and disc-harrowed in the autumn.
How do you prevent wireworms in potatoes?
Cultural Control
Avoid planting potatoes in fields immediately following clover, grass, pasture, or weedy alfalfa. Summer fallow will reduce wireworm numbers by drying the soil.
How do I keep bugs from eating my potatoes?
A very successful cultural control for potato beetle is crop rotation, according to Groves. Because the pest walks instead of flying to get to its food in the early season, rotating potatoes at least ¼ mile away from previous year’s potato is an effective cultural control measure.

What insecticide kills wireworms?
Treatments for wireworms should not be applied unless wireworms are known to be present or have caused damage in the previous season. A few insecticides (active ingredients) that may be used in home gardens for the management of wireworms include bifenthrin (3A), pyrethrins (3A), and zeta-cypermethrin (3A).

Sunken and often shriveled areas on the surface of infected tubers are the most obvious symptom. When tubers are cut through the affected areas, tissues appear brown and collapsed, often with a white, pinkish, or yellow fungal growth, which may extend into the center of the tuber.
Is potato wart harmful to humans?
Potato wart is a soil-borne fungus that can remain dormant in a field for more than 40 years. Although potato wart poses no threat to human health or food safety, it has an impact on the economic return for potato growers by reducing yield and making potatoes unmarketable.
Is it OK to eat scabby potatoes?
Scabby potato tubers, while unsightly, are still edible. Infected potatoes need only be peeled before use. Store tubers with scab in a cool, dark, dry place to reduce the possibility of scabby areas becoming infected by soft rot bacteria that will totally decay tubers.
How do you treat wireworms in soil?
Rotations with non-host crops such as onions, lettuce, alfalfa, sunflowers and buckwheat will reduce wireworm populations. Rotations with tomatoes, sugarbeets or corn may also help as these crops presently have labeled insecticides.
How do you get rid of wireworms in garden soil?
How to Get Rid of Wireworm Pests. Wireworm control involves taking a soil sampling for wireworms or inspecting the soil after plowing in the fall. Dry flour baits can be inserted into the soil using a corn planter. Twenty-five baits should be put out per acre, and these traps should be checked every couple days.

How nematodes affect potatoes?
Root-knot nematode feeding reduces the vigor of plants and causes blemishes on tubers. The latter can lead to a severe reduction in tuber quality and, as a result, affected potatoes become unmarketable. Lesion nematodes damage roots by feeding and moving through cortical tissues.
