Spider Control & Extermination in the Dallas / Ft. Worth Texas Metroplex
Spiders are one of the most feared home invaders. There are more phobias about spiders than any other pest, and understandably so. If you get bitten by the wrong spider – a black widow or a brown recluse – and you have a bad reaction to the venom, you can end up in the hospital. And yes, there have even been some deaths associated with spiders (though much less than you would think – six per decade in the U.S.).
Tens of thousands of spider species have been identified throughout the world. These arachnids have eight legs and two body segments. Spiders have three or four pair of eyes. Many spiders have poor vision, but some species of spiders, such as the jumping spider, have exceptional vision.
Spiders do not have chewing mouthparts and commonly utilize digestive enzymes in their saliva to break prey down before consuming it. Additionally, the gut of a spider is too narrow to allow for consumption of large food particles. Almost all spider species are predators, although one plant-feeding species has been documented.
Spiders are capable of producing silk that is elastic, adhesive and strong. This silk is used to spin webs as well as to construct egg sacs and line spider dwellings. The size and shape of spider webs vary by species: some are orb-shaped, while others are funnel-shaped; some webs are orderly, while others appear haphazard. Some spider species live in burrows rather than webs, while others are free ranging and take refuge in crevices.
Effective Control of Indoor Spiders
An effective approach to spider control is to use the knowledge that they are predators; they primarily consume other insects. So if you can reduce the other insects around your home, spiders will be less interested in hanging around. Most spiders like to hang out near light sources, as they rely on flying insects that instinctively move towards light. A web-spinning spider worth his salt will let his meals come to him. In addition to web-making spiders, there are hunting spiders. They are athletic and really do run down prey. A subcategory of hunting spiders is jumping spiders. If you’ve seen one of those, you recognize it. They have more of a pouncing behavior to capture their prey. The spiders with short, stubby legs are almost all of the jumping variety. The spiders with long – but not delicate – legs are the running spiders. These include wolf spiders and brown recluse. You won’t find those spiders spinning a web.
The best way to control running and jumping spiders at home is to control their food sources around the house – again, get rid of your other bugs. Crack and crevice treatment with insecticides provide some control, but you can also use glue boards or sticky traps. These are non-pesticide capture mechanisms. Some can be folded into a box shape so that unintended items won’t get stuck to them. There are really no attractants in most of these glue traps. Some companies try to add a scent, but the most attractive thing for a spider is a bug stuck in the glue trap. They may be cued visually by this. As a Pest Management Professional, we often see a glue trap with a bug in the glue with a spider stuck right on top of it.
The sticky trap, or glue trap, just captures them – if they walk through the trap, they die. The disadvantage is that you cover less surface area with a trap. The most effective places to put glue traps are in dark, quiet areas. A closet is a good example, or between a bed and a wall, or by any piece of furniture – these are all common traffic patterns for spiders.
Glue traps can also point you towards the source of the infestation – how they are getting into the house. If you have 6 spiders trapped on the right hand side of a glue trap, then look toward the right, along the wall, and look for an opening like a door or wall socket. Perhaps it’s a crack that you can caulk.
But one good point about spiders is that they are basically loners – they aren’t social insects that live in big groups, like ants or bees. As predators, they like to operate on their own and not share their food. So you’re often just as effective whacking a spider with a shoe or a newspaper as you would be to spray for them.
Effective Control of Outdoor Spiders
Spiders are not easily controlled, whether inside or outside the house. They are often abundant around the outside of the house, especially around outdoor lights. Insects are attracted to outdoor lights at night, and spiders are there to hunt for insects. Spiders are predators of insects. This is their food, and this is where they will be most abundant and active. A program to reduce the spiders around the outside of the house should begin by reducing the presence of insects around the outside of the house.
When spiders occur outside the house in large numbers, such as on the siding or on the ornamental shrubs, try to reduce the use of outdoor lights. The most common spiders around the outside of houses are wolf spiders. These are the large and often ”hairy” spiders that are hunters and do not make webs. Next in abundance would be the web-making or orb-weaver spiders. Orb-weaver spiders are often bright yellow and black.
Spraying outdoors to control spiders is usually not effective. Web removal and elimination of their food source, insects, is a much better way to resolve these issues.
