Due to the potency of its venom, the black widow spider is perhaps the most feared spider in Colorado. It is reported to be 15 times stronger than that of a rattlesnake. Humans would be at far greater risk if its aggressiveness matched the potency of its venom. Black widow spiders usually only bite humans when their web is disturbed and are otherwise shy. Generally, black widow loves warmer climates, but they can be found nearly everywhere throughout the U.S. Since they prefer warmth, many people wonder what their behavior is in the winter. Today, we at Effective Pest Services would like to share the basics of black widow spiders, particularly how they handle surviving the winter months.
Where Do Black Widow Spiders Live?
For the most part, black widow spiders stay outdoors. In crevices or recesses within block walls, sprinkler valve boxes, rock piles, and undersides of patio furniture, black widows build irregular erratic looking webs where they live. Additional popular spots to find black widows includes outdoor sheds, garages, and playground equipment.
How Do You Know if You have a Black Widow Infestation?
The presence of webs in the home or on the property is one of the most obvious signs of a spider infestation. Messy and irregular webs located near ground level is usually constructed by black widows. Another sign that a spider infestation is underway is finding a silken sac, which holds eggs, in the doorway. Professional black widow spider extermination services may be necessary if you see any of these signs.
Do Black Widow Spiders Die Off in Winter?
In cold locations, such as Colorado, black widow spiders go into a state known as overwintering. Black widow spiders look for warmer locations to hunker down for the season as the weather gets cooler. She may find a suitable place where she can overwinter just like a hibernating bear once the black widow spider enters a storage shed, garage or home. To conserve energy, the spider’s metabolic rate slows. Because they are adapted to live through cold months in a low-energy state, winters do not harm black widow spiders. They become dormant after they tuck in their legs.
How to Prevent Black Widow Spiders?
