Black Widows in Roseville Garages: Where They Hide
Black widows in Roseville garages hide in dark, undisturbed spots close to the floor: behind stored boxes, under shelving, in corners at the garage door and inside rarely used equipment. The local species is the western black widow (Latrodectus hesperus). Its messy, tangled web near ground level is easier to spot than the spider itself, which stays hidden during the day.
How Do You Identify a Black Widow?
You identify a female black widow by her shiny black body, about 1/2 inch long, and a red hourglass mark on the underside of the abdomen. Males are smaller, brown and patterned, and do not bite people. Black widow webs are irregular and sticky, with strong silk that crackles when touched, unlike the neat orb webs of garden spiders.
Where Do Black Widows Hide in a Garage?
Black widows hide in 6 common garage spots:
- Behind storage boxes stacked against walls.
- Under shelving and workbenches.
- Bottom corners of the garage door, where seals are worn.
- Inside shoes, gloves and helmets left on the floor.
- Behind water heaters and around utility lines.
- Inside unused equipment: coolers, kids' toys, camping gear.
Where Do Black Widows Hide Outside?
Outside, black widows hide in irrigation valve boxes, meter boxes, BBQ island cavities, woodpiles, block-wall holes and under patio furniture. Roseville's hot, dry summers drive them into these shaded, protected spots. Reach into valve boxes and woodpiles with gloves on.
Are Black Widow Bites Dangerous?
Black widow bites are rarely fatal, but they are medically significant. The venom is a neurotoxin that causes muscle pain, cramping and sweating within hours. Children, older adults and people with heart conditions face greater risk. Call Poison Help at 1-800-222-1222 or seek medical care after a suspected bite.
How Do You Reduce Black Widows in a Garage?
To reduce black widows in a garage, take away their hiding spots and their food.
- Store items in sealed plastic bins instead of cardboard boxes.
- Keep stored items off the floor and away from walls.
- Replace worn garage door seals.
- Switch exterior lights to yellow bulbs to attract fewer insects for spiders to eat.
- Vacuum webs and egg sacs, then empty the vacuum outdoors.
