Small holes in a yard are not automatically wolf spider burrows. Some wolf spiders use shallow retreats, but holes can also come from insects, earthworms, rodents, or other animals. This guide explains how to inspect a suspected burrow, reduce conditions that attract spiders, and choose a safe response without needlessly damaging your lawn or harming wildlife. You will need only basic protective gear and, if the hole is active, a way to observe it from a distance.
What You’ll Need
- Closed-toe shoes and work gloves for yard inspection.
- A flashlight and phone or camera to document the hole and its surroundings.
- A ruler or coin to show the opening’s approximate size in a photo.
- Optional: a clear container and stiff card, only if you are confident handling a small spider safely.
Step-by-Step
- Look without disturbing the opening. Inspect during daylight, when you can see the ground clearly. Keep children and pets away while you check. Do not put a finger, stick, hose, or tool into the hole; a spider may be inside, and probing can injure wildlife or collapse the burrow.
- Record what you see. Photograph the opening beside a ruler or coin, and note its location, soil type, nearby plants, and whether there is a loose soil mound or webbing. Look for tracks, droppings, clipped vegetation, or multiple openings. A round, small hole alone cannot identify the animal that made it.
- Observe at a distance, if needed. Some wolf spiders are active at night, and certain species make burrows, often in bare or lightly vegetated ground. Watch from a safe distance near dusk with a flashlight. A spider may sit at the entrance or move nearby, but absence during one observation does not prove the hole is abandoned. Do not try to force an occupant out.
- Consider other causes. Depending on hole size, shape, and location, the opening could be made by a bee, wasp, beetle, earthworm, or small vertebrate. Many ground-nesting insects are beneficial. If the hole is large, there are many holes, or you see signs of animal activity, consult a local extension service or wildlife professional before treating it.
- Decide whether action is necessary. Wolf spiders generally hunt insects and do not build the large, conspicuous webs associated with some other spiders. If the hole is in an out-of-the-way part of the yard and no one is at risk, leave it alone. Removing a spider is usually unnecessary. If it is beside a doorway, play area, or frequently used path, first keep people away and consider relocating the spider only if you can do so safely.
- Relocate only a visible spider, not the burrow. Wear shoes and gloves. If a small spider is clearly visible, place a container over it and slide stiff card underneath, keeping your hands away from the spider. Release it in suitable sheltered habitat away from doors and heavily used areas. Do not handle a spider directly, and do not attempt this if you are unsure of the identification or feel unsafe. For a larger or inaccessible animal, contact a pest professional.
- Make the area less inviting. Trim grass and groundcover around paths, clear leaf litter and clutter near the house, and move firewood or stored items away from exterior walls. Reduce outdoor lighting that attracts insects, or use a shielded, warm-colored bulb where practical. These steps reduce hiding places and prey; they do not guarantee that spiders will leave or prevent future burrows.
- Fill the hole only after checking it. Do not fill an active or unidentified burrow. If you have good reason to believe it is empty and the opening is a nuisance or trip hazard, gently rake in loose soil and level the surface. Avoid pouring chemicals, boiling water, gasoline, or other substances into it. Check the spot over the next several days for a reopened hole.
- Ask for local help if the problem persists. Take clear photos and note when activity occurs. A county or university extension office can often help identify likely burrow makers from local species and signs. If a spider is inside the home, there are repeated sightings in a sensitive area, or someone has been bitten, use a qualified pest professional or seek medical advice as appropriate.
Common Mistakes
- Assuming every hole is a wolf spider burrow. Many unrelated animals make small openings, and some insects nesting in soil are beneficial. Identify the likely cause before acting.
- Pouring pesticide or household chemicals into the hole. This is unreliable, can contaminate soil and water, and can harm pets, children, and non-target wildlife. Follow product labels and local rules; do not use a product in a way its label does not allow.
- Flooding, digging, or poking the burrow. These methods can injure the occupant, damage roots, and make identification harder. They may also drive an animal into an unsafe or inaccessible place.
- Expecting yard cleanup to eliminate spiders. Reducing clutter and insect prey can make an area less attractive, but it will not create a spider-free yard. Spiders are part of a normal outdoor ecosystem.
- Handling an unidentified spider. Identification from a quick glance is unreliable. Keep a safe distance and use a professional if capture or removal is necessary.
Tips
- Use a photo rather than getting close; include a size reference and the surrounding ground.
- Check under outdoor items only after lifting them cautiously, wearing gloves, and keeping your face and hands clear.
- Keep lawns and play areas tidy, but avoid broad-spectrum pesticide use as a routine prevention measure.
- Teach children to leave spiders and holes alone and to tell an adult about them.
- If you are bitten, wash the area with soap and water and apply a cool compress. Seek urgent care for severe symptoms, trouble breathing, or a rapidly worsening reaction. If possible, take a photo of the spider without trying to catch it.
Troubleshooting
The hole reappears after you fill it: An animal may still be using it, or a different cause may be creating the opening. Stop filling it, observe from a distance, and request identification help if needed.
You cannot tell what made the hole: Do not guess from size alone. Photograph it, note nearby signs, and contact a local extension office. Avoid pesticides until the pest is identified and a treatment is justified.
You see a spider but cannot safely contain it: Leave it undisturbed, restrict access to the immediate area, and call a pest professional. Do not try to trap it with bare hands or spray it at close range.
The hole is near a child’s play space or a pet area: Temporarily block access and supervise children and pets. Once the burrow is identified and no occupant is present, level the hole and adjust nearby groundcover or clutter. If activity continues, seek local advice rather than repeatedly treating the soil.
Frequently Asked Questions
Do wolf spiders make holes in yards?
Some species dig or use burrows in soil, but many wolf spiders shelter under leaves, stones, or other cover. A hole by itself is not proof of a wolf spider.
How can I tell if a hole is active?
Look for an occupant or repeated activity from a distance, especially around dusk. A clean opening or nearby loose soil is not enough to confirm activity or identify the animal.
Should I fill in a wolf spider hole?
Usually, no action is needed if it is away from people. Do not fill it while it may be occupied. If it is empty and presents a nuisance or hazard, level it gently with soil.
Are wolf spiders dangerous to people or pets?
They are not generally aggressive, and bites are uncommon. Avoid handling them; a bite can cause localized pain or irritation. Contact a medical professional or veterinarian for concerning symptoms.
Will insecticide get rid of the holes?
It may not reach or control an animal in a burrow, and it can harm beneficial insects and other wildlife. Identify the hole maker first and use pesticides only when necessary and strictly according to the label.
When should I call a professional?
Call for help if you cannot identify the animal, the opening is near a high-use area, activity keeps returning, or you are uncomfortable approaching it. A local extension service can help identify it; a licensed pest professional can discuss appropriate options.
