How do I tell a brown recluse from a wolf spider?
Check the eyes, legs and markings. A brown recluse is smaller, smooth and evenly tan, with a dark violin shape on its back and six eyes set in pairs. A wolf spider is bigger, hairy and striped, with eight eyes and a fast, running habit. Recluses hide in clutter; wolf spiders roam the floor.
Plenty of brown spiders carry some kind of mark behind the head, so a violin shape alone is not proof. Recluse legs are one solid color with no bands or stripes. If you can, trap the spider under a jar for the technician.
Wolf spiders show up most in fall, slipping under doors with worn sweeps. They bite if handled but are not the medical concern a recluse can be.
Where do black widows hide on rural property?
Black widows pick dark, sheltered spots close to the ground: under stacked firewood, inside water meter and valve boxes, under the lip of plant pots, beneath outdoor furniture and in the corners of sheds, well houses and barn stalls. Wear gloves when reaching into any of them, and look before you grab.
On acreage they also turn up under feed troughs, in stacks of T-posts, inside old tires and under mower and tractor seats. The round egg sacs hang inside their strong, irregular webs.
Cleaning out those spots and storing firewood off the ground, away from the house, does more good than spraying the whole yard.
Why do webs keep coming back on my lake dock and boathouse?
Lights and water draw insects, and insects draw spiders. Docks, boathouses and lake-facing porches collect midges, mayflies and moths on summer nights, so orb weavers and fishing spiders keep rebuilding. Regular web removal, warmer-colored lights and treating the framing where spiders shelter keep the buildup manageable.
Fishing spiders on dock pilings can span the width of your palm, but they are shy and not considered dangerous. Orb weavers rebuild overnight, so sweeping alone buys only a few days.

What should I do if I think a brown recluse bit me?
Wash the bite with soap and water, put a cool compress on it and save the spider in a jar if you can. Call your doctor or Poison Help at 1-800-222-1222 if pain grows, the skin darkens or blisters, or you feel sick. Get emergency care for trouble breathing or severe cramping after a widow bite.
Many sores blamed on recluse bites turn out to be skin infections, which is another reason to see a doctor rather than guess. Bring the spider along if you caught it.
