Wasps in Gutters and Downspouts: What to Do

You’re cleaning up the yard and notice wasps circling the corner of the roof, landing under the gutter and flying off again. Wasps in gutters are common in Northwest Ohio from late spring through fall. The gutter itself is rarely the problem. It’s what the wasps are building just under it or behind it. Here’s how to tell what you’re dealing with and why the ladder is the part to skip.

What Wasps Build Around Gutters

Paper wasps are the usual suspects. Clemson Extension describes their umbrella-shaped paper nests built in protected spots, including roof overhangs, porch ceilings, and window and door frames (Clemson HGIC: Paper Wasps). The underside of a gutter or the fascia board behind it fits that description well. You’ll usually see open, six-sided cells facing down.

Yellowjackets are a different story. Ohio State University Extension notes they nest in protected cavities, including wall voids (OSU Extension HYG-2075). Wasps disappearing into a gap behind the gutter, the fascia or the soffit, with no visible comb, usually means an enclosed nest inside. See wasps in your attic or soffit for that case.

Why the Ladder Is the Real Risk With Wasps in Gutters

A few stings on the ground are painful. A few stings at the top of a ladder can mean a fall. The CDC’s National Institute for Occupational Safety and Health notes that many ladder injuries happen at home, and that in about 40% of cases the cause is a ladder sliding out at the base from an incorrect setup angle (CDC NIOSH Ladder Safety). NIOSH also lists overreaching and carrying objects while climbing as common causes. Holding a spray can overhead while leaning toward a gutter checks both boxes.

Extension ladder leaning against a two-story house, the climb people try when they see wasps in gutters — Climbing toward an active nest puts you at height with no easy way to back off.

Paper wasps are not usually aggressive, but Clemson notes they will sting if they feel threatened. Spraying from a ladder is exactly that kind of threat, and you can’t back away quickly from the top rung.

What to Do Instead

Stay on the ground. Note which corner and how high the nest is.
Take a zoomed photo of the nest, plus a wider shot of that side of the house.
Keep people clear of the area below, especially doorways and downspouts kids play near.

We remove nests by hand or vacuum with no pesticides. Native paper wasps are relocated. European paper wasps, yellowjackets and hornets are removed. Our guide to native vs. European paper wasps explains the difference.

Frequently Asked Questions

Do clogged gutters attract wasps?

Standing water can draw thirsty insects, but nest sites are the main attraction. See what attracts wasps to your yard.

Can a new nest show up next year?

Yes. Clemson notes that queens overwinter in cracks and crevices around structures and start new nests in spring. Our wasp prevention guide covers sealing up.
