A call came in today, “spiders come quick”. We sent out our tech and sure enough it was the dreaded Black Widow. The home had been vacant for some time and the new owner was remodeling with a plan to resell but he was going to live there in the time it took to fix up the place. Mind you this man is a professional motorcycle road racer, scuba diver, avid pilot and deals with 1000 pound animals on a daily basis for his job. But his knees sorta buckled when it came down to a tiny spider that didn’t even weigh 1/2 of an ounce. The Black Widow is a terrifying pest indeed and all totaled we did kill 20 or more around his home. Is our fear of Black Widows another product of misunderstanding?
Not an insect and as such most residual sprays and treatment techniques fall short for their control long term.
Her bite can be some 15 times more poisonous that a Prairie Rattle Snake. Rarely does a Black Widow bite kill humans.
She lays 300 to 400 eggs—-the spider lings are not poisonous but they are cannibals.
Not a hunting spider she hides in dark moist places and her web is usually a mess with entangled debris.
Not always black. Some can be tanish or even a camo version.
Yes she sometimes kills her male counterpart after mating. (That’s how she got her name).
Where do Black Widow spiders live
Black Widows spiders are almost always found in undisturbed areas. That doesn’t always mean way up in the attic in the farthest hard to reach corner. On the contrary you probably pass a Black Widow spider everyday in your daily travel. This just means areas that things aren’t moved around a lot or in areas that are hard to access. Common areas include; garage door jams, under rails of porch rails, frame work of pool enclosures, under patio furniture, in the lips of flower vases, storage on shelving, etc. The list goes on but basically these spiders will set up shop where bugs frequent but will rarely be in plain sight. The widows nest is not a thing of beauty. It’s a very messy web that collects leaves and debris. Usually it will descend outward away from her resting spot with several ‘trip lines’ that intersect with an insects likely path of travel. Once a bug brushes up against the ‘line’ she goes into action. The bug may become entangled which makes her job easier. However this vixen is able to swoop down and actually lasso this meal with her web. The widow uses this technique quite effectively against scorpions. Her eggs are almost always up in or real near her resting area. She spins an extra thick sheet of webbing to create a chamer where she’ll spend most of her time waiting for her next meal.
