A Lehi resident has raised alarms after discovering more than a dozen black widow spiders on a retaining wall adjacent to a public sidewalk. Local pest control experts suggest a warm winter has led to an unusual explosion in spider populations this year.

Key takeaways

  • A Lehi resident discovered over twelve black widow spiders on a private retaining wall near a public sidewalk.
  • The City of Lehi stated that pest control for the wall is the responsibility of the private property owner.
  • Entomologist Trent Frazer reported an 'exploding population' of black widows due to a warm winter allowing earlier reproduction.
  • Experts warn that spiders often hide in dark, undisturbed areas such as wood piles, sprinkler boxes, and outdoor footwear.
  • Local parents are increasing their monitoring of children playing outside for signs of spider webs.

A Lehi woman is raising community concerns after finding more than a dozen black widow spiders along a retaining wall located next to a public sidewalk. The discovery, which was shared in an online community group, has sparked local debate regarding property responsibility and the safety of neighborhood walking routes used daily by families.

Community concerns over property responsibility

The spiders were found on a retaining wall that sits on private property, though the wall is positioned along a path frequently traveled by local residents. Because of its proximity to the public sidewalk, the discovery prompted questions within the community about how much concern should be warranted and which party holds the responsibility for treating the area for pests.

The City of Lehi clarified to KUTV that because the retaining wall in question is located on private property, the responsibility for addressing pest control measures lies with the homeowner rather than the municipality.

Warm winter drives spider population

Trent Frazer, a board-certified entomologist and owner of Falcon Pest Control, noted that this year has been particularly unusual for black widow activity. According to Frazer, the population appears to be experiencing an explosion.

Frazer attributed this surge in spider numbers to weather conditions experienced earlier in the year. He explained that a warmer winter allowed the spiders to begin their life cycles earlier than usual, which subsequently led to increased reproduction rates and a higher number of egg sacs.

Identifying high-risk hiding spots

To mitigate risks, Frazer advised residents to remain vigilant in dark, undisturbed areas around their homes. He specifically identified wood piles placed against houses, sprinkler boxes located under porches, and even shoes left outside as primary hiding spots for the venomous spiders.

While Frazer noted that black widow bites are typically not fatal, he emphasized that people should still take necessary precautions, particularly when inspecting areas where spiders are known to thrive.

Parental vigilance in Lehi neighborhoods

For local parents, the presence of venomous spiders near public walkways is a significant worry. Melissa Taylor, a nearby resident who manages pest control for her own property, expressed that the discovery is a primary concern for her as a mother.

Taylor stated that she maintains constant awareness when her children are playing outdoors, specifically looking for signs of webs or other indicators of spider activity. While she has not personally observed an increase in black widow sightings this year, she believes the current period may represent only the start of the season.

Ongoing seasonal outlook

As the summer progresses, residents are encouraged to check dark crevices and outdoor storage areas. With the entomologist's warning that this year's population is uniquely high due to early seasonal starts, monitoring residential perimeters remains a key recommendation for local families.
