About this bug

Often called daddy longlegs, a long-legged arachnid with a single fused, oval body and no venom glands. It scavenges on dead insects, fungi and plant matter.

You'll usually find harvestmen in gardens and on plants, in woods and along trails and in basements and garages. They are most active in summer and fall.

When you'll see harvestmen

Typical places to check: garden or plants, woods or trails and basement or garage.

About ticks, mites & other arachnids

The harvestman is one of the ticks, mites & other arachnids. This group includes ticks, mites, scorpions and harvestmen. Like spiders, adults have eight legs and no antennae, though larval ticks and chiggers have only six. Ticks and some mites feed on blood or skin, while scorpions hunt insects and harvestmen scavenge.

Ticks move through larva, nymph and adult stages, and each stage needs a blood meal. Nymphs are tiny and active in late spring and summer, which is when many tick-borne infections happen.

Should you get rid of it?

No control is needed. Harvestmen are not pests, and many help by eating other insects or pollinating plants. If one is indoors, move it outside with a cup and a sheet of paper.
