Monitors, not a spray plan
Best spider traps
The best spider trap is a glue monitor in the corner the spider already uses. It catches wanderers: house spiders, cellar spiders, and the occasional wolf spider that walked in. It does not clear a woodpile of Black widow or prove a brown mark is a Brown recluse. If you cannot see the spider, do not reach into the clutter. Use the trap to learn whether anything is moving, then reduce the clutter and seal the sill.

Best folded trap: TERRO spider and crawling-insect traps. TERRO-style spider traps stand in a corner or along a sill. Check them so a catch does not become a month-old specimen. They are non-pesticide glue. Pets still stick.

TERRO spider and crawling-insect traps
Best folded trap — TERRO-style spider traps stand in a corner or along a sill. Check them so a catch does not become a month-old specimen. They are non-pesticide glue. Pets still stick.
Hardware
Catchmaster 72MAX glue boards
Best flat board — The board monitors recluses in their actual range better than a tall tent trap, because it slides into the gap. Outside that range, a “recluse” on the board is usually something else. Identification still matters.
Hardware
Headlamp or flashlight for inspections
Best before you buy more traps — A light into the eave or the water-heater gap tells you if you need a trap or a vacuum and a pair of gloves. Spray into a void you have not looked at is how non-target animals get hit.
Traps do not identify a medically important spider
A glue board is a bad place to learn widow or recluse anatomy after the spider is torn. If you live in recluse range and you are finding flat boards full of brown spiders in a closet, stop treating every one as a recluse and compare eye pattern and markings with a reliable source, or ask an extension office. Most US homes outside that range do not have brown recluses. A fogger is the wrong response either way.
Common questions
What is the best trap for brown recluses?
In actual recluse range, flat glue boards along wall-floor joints and under furniture, checked often, plus clutter reduction. The board is a monitor. It is not a reason to fog the bedroom.
Do spider traps attract more spiders?
They catch spiders already moving through that corner. They do not bait a new population in from the yard. Seal the door gap if the catches are outdoor wanderers.
Are sticky spider traps poisonous?
The ones in this guide are glue, not a pesticide. They are still a problem for pets, small wildlife, and a child who grabs the board. Place them deliberately.
