Identifying Dangerous Texas Spiders

As a resident of the Texas Hill Country you should be familiar with the basic variety of potentially dangerous pests that are native to the area. Here are the 4 most dangerous spiders in the Canyon Lake / Bulverde area:

Brown Recluse

The brown recluse is the most common spider that can cause harm in Texas and the Southern United States.  It is a light tan or brown and identified by the violin-shaped marking on its head and thorax.  They prefer dark, undisturbed areas like closets, attics, basements etc.  They will also hide in piles of clothes and under furniture.

Their venom causes necrosis (tissue death) in severe cases.  The bite will start as a small blister and develop into a painful ulcer.

Black Widow

Black widow spiders have a neurotoxin venom affecting the immune system causing pain, muscle cramps, nausea and sweating. Although dangerous they are rarely fatal with proper medical treatment.  They are shiny black with a red hourglass marking on the underside of the abdomen.  Seeing one in person is actually fairly rare because they stay in dark, undisturbed areas like garages, wood piles, water main boxes.  As a professional pest control operator I have only seen 2 live black widows in all my years doing pest control.

Wolf Spider

Wolf spiders are generally not dangerous to humans but their bite can cause an allergic reaction and/or swelling and redness.  They are more active hunters and do not spin webs to catch food.  They are usually fairly large, hairy, and brown, gray or black colored.  They will hide in grass, logs, and yard debris like leaves and piles of mulch.

Brown Widow

Brown widows are similar in size and shape to the black widow but usually tan colored with the same red markings on the abdomen.  It will have banded markings on the legs and some of them will be nearly black.  They are known as cobweb spiders with their irregular webs.  They have egg sacs one cm in diameter and known for their spiky appearance.  Their natural predators are mud daubers.  Bites are not as serious as a black widow, causing fever, muscle cramps, abdominal pain, weakness in legs and difficulty walking.

As much attention and fear that spiders invoke, serious reactions are not very common.  Even in one instance where hundreds of brown recluse spiders were found in a home, the residents had no complaints of bites. 

Most spiders do not have strong enough mouthparts to even puncture human skin. Proper identification needs to be made when assessing skin irritation or possible bites.

Even if you are terrified of spiders, know that they are not out to get you! Spiders play an important role in the ecosystems around your residence. Spiders that are not venomous should be left in place if possible because they contribute to biological control (i.e. eating other insects). If you are determined to get rid of them here are some tips and tricks to control populations.

Spiders are difficult to control because they hang out in dark, cluttered areas away from predators and  humans.  Places like closets, garages, attics, wall voids and under furniture are prime habitats for 8-legged arachnids to live.

Inspections & Monitoring

A proper inspection is needed to determine the species and numbers of active spiders in a home.  Check in the corners of closets, around light fixtures, under cabinets, inside cabinets, behind or inside boxes in garages, around electrical outlets, as well as around vegetation on the outside of the foundation.  I tend to find the most spiders around light fixtures that stay on all night and in garages where there is plentiful prey for spiders.

Natural Control Methods

Glue boards, also called sticky traps, are a great way to monitor activity and find problem areas.  This will help to properly identify which species are the problem as well as reduce other pest populations that go in the traps too!  Removing and brushing away webs will also help reduce populations and irritate them so they will hopefully move on to another nesting area.  Keeping bushes and trees trimmed away from the house a few feet will also help reduce harborage locations for spiders and other insects and also eliminate direct pathways for bugs to enter your house.

Filling in weep holes with mesh products like copper, stainless steel, or steel wool help keep eliminate entry points.  Sealing plumbing and air conditioning pipe penetrations will help with other problem insects as well as spiders.  Removing clutter and keeping storage items in tightly sealed containers take away dark habitats that spiders enjoy.

The most effective control measure I have found at my own house is switching to amber light bulbs on any lights that stay on at night.  With newer LED bulbs in modern homes the insects are attracted to them at night and spiders spin webs where those lights are to catch prey.  Switching to the amber or yellow bulbs makes a tremendous difference.  Turning off all lights at night is recommended, but not always practical.  Closing blinds at night will also help.

Natural Predators

Spiders are prey to lizards, birds, toads, frogs, and other spiders. Although it would be difficult to rely solely on natural predators to gain control of spider populations, creating a habitat that is hospitable for these predators will help the spider populations decrease slightly.  The frogs will also help with mosquito control.

Chemical Control

I can say that after many years in pest control around Canyon Lake, Bulverde and Spring Branch, we can achieve about 80% or so reduction in spider populations with just a general pest control treatment alone, without doing a whole lot of extra exclusion or deep cleaning.  Using a good residual concentrate designed for spiders along with proper use of dust products in voids and attics can greatly reduce the spider numbers as long as the service is maintained.

With the homeowner adding in some weep hole sealing, sealing gaps and cracks, de-cluttering, and other housekeeping measures, spiders can really become a non-issue.

Mosquitoes can be a significant nuisance in the Texas hill country, making spending a time in your yard an awful experience. With proper preparation and management however, you can minimize their impact.

Preparation

Start by removing standing water around your property since mosquitoes breed in stagnant water. Empty containers, fix any leaks, and ensure proper drainage. Keeping your yard well-maintained by trimming vegetation and mowing the lawn reduces mosquito resting places. Installing screens on windows and doors is essential to keep mosquitoes out of your home. Additionally, applying EPA-approved mosquito repellents to exposed skin and clothing can help protect you from bites.

Dealing with Mosquitoes

Using mosquito traps in areas with high mosquito activity can significantly reduce their numbers. Encouraging natural predators like bats and birds by providing suitable habitats is another effective strategy. Treat any standing water that cannot be removed with larvicides to kill mosquito larvae before they mature. When outdoors, especially during peak mosquito hours at dawn and dusk, wearing long sleeves and pants provides an extra layer of protection.

Professional Help

If mosquito problems persist despite your best efforts, consider hiring professional pest control services. Professionals can offer comprehensive solutions, including targeted treatments and ongoing maintenance, to help manage mosquito populations effectively.

By taking these proactive steps, you can reduce the mosquito population around your home, making your environment more comfortable and safer during the mosquito season in South Texas.

No matter how clean and well-maintained your home may be, pests have a knack for finding their way inside. New Braunfels residents can face pest invasions from fire ants, spiders, scorpions and more.
