In Arlington, spider season never really seems to end, even as other Texas cities see a significant decline in arachnid activity come November. The city is kept at what feels like summer temperatures well into fall by its location in the naturally warmer microclimate of the Dallas-Fort Worth metroplex.
However, for homeowners, this extra warmth can mean one thing: spiders are not leaving anytime soon. November is actually the most October-like month of the year in Arlington, as daytime highs often reach the 70s. This lovely weather, which has us wanting to do all the things outdoors, also means prime time for spiders to be out and about, still hunting, and, yes, getting into your house. Mild temperatures, combined with our use of indoor heating, can only lead to one thing: spider season.

Arlington’s November Climate: The Perfect Setup for Spiders
November gives an average city temperature between 18-20 °C, according to the National Weather Service, with many days landing in the mid–70s. That warmth allows insects to remain active much later than they do in northern climates, and spiders follow them. Additionally, the urban heat island effect generated by cities due to concrete, buildings, and limited vegetation in developed areas raises nighttime temperatures by another 3-5 degrees.
This ensures that prey is plentiful for spiders and that their metabolism remains high enough to keep consuming and reproducing. As the occasional cool front pushes through, the warm interior of your house becomes even more enticing, pulling the critters in to find a regulated temperature they can settle into.
Common Spider Species Active in Arlington This Season
- Wolf Spiders
These web-free ground-hunters actively chase down their prey. One reason wolf spiders remain active into November in Arlington is that insects are still present. You will usually see them running across floors or hiding inside garages. Although intimidating with their stout bodies and reaching up to an inch long, they are not considered dangerous to humans.
- Brown Recluse Spiders
Brown recluses are perhaps the most worrisome spiders for Arlington residents, as they thrive in the region’s temperate climate. They like secluded areas such as closets, attics, and maybe storage containers. With North Texas housing large populations of brown recluse spiders, as reported by Texas A&M AgriLife Extension, proper identification and prevention are key for homeowners.
- Common House Spiders
You see these web-making spiders in corners, near windows, along ceiling edges, and the like. They pose no danger and do more good than harm, but visible webs in your home are not very inviting.
Preventive Steps for Arlington Homeowners
Doing so now will significantly minimize the spider presence for the long season ahead:
- Seal cracks in windows, doors, or foundations where spiders often get into the home.
- Minimize outdoor light by entranceways, as lights attract insects that spiders eat
- Remove all vegetation that touches your house. Plants are the highways for spiders into your house
- Get rid of clutter in garages, basements, and closets where spiders can nest in peace.
- Keep webs found, egg sacs, or spiders all by cleaning regularly prior to populations getting out of control
- Moisture problems are common since most insects (spider food) love to live in damp areas
Professional Spider Control for Arlington’s Extended Season
But when prevention fails — and it often does during Arlington’s long spider season — professional help is essential. With years of experience serving Arlington homeowners, Romney Pest Control recognizes the unique challenges posed by our climate. The team knows that successful spider control here is not simply about treating and controlling spiders, but about a comprehensive program that addresses the underlying insect activity that allows spiders to thrive on food sources.
Their team understands the behavior of local species, knows where brown recluse spiders seek shelter in an average Arlington home, and can apply treatment methods suited to the long, warm season in this city. They are designed for long-term prevention instead of individual treatments, responding to Arlington’s seasonal climate. This strategy recognizes what locals already know: spider season here does not operate on a calendar but instead on temperature.
