Avoid Getting Tangled Up in Spider Trouble Calls this Season!


The return of morning spider webs is an iconic image of spring. And, for the pest management professional, it marks the beginning of a busy season ahead. Spiders have been one of the leading drivers of new and repeat pest control business for decades. While calls may be spurred by the occasional arachnophobic episode requiring extra care – many customers simply want a home free of cobwebs and creepy crawling guests. Sometimes, this is easier said than done. Now is a great time to review your knowledge of spider control and possibly pick up a few new tips from the field.


Crawling Spiders


Crawling spiders are solitary creatures that are on the move looking for food or mates. Often they will find their way into homes and businesses where they are far from welcome. Common culprits are active hunting spiders like Wolf and Jumping Spiders or passive hunters like Trapdoor Spiders, who only go on the move during mating season. When found indoors the primary focus should be exclusion, focusing on any opening that spiders can access. In most cases, it is as simple as finding an exterior door with daylight coming under when looking from the inside. Check all door sweeps for wear. A door with an eighth of an inch gap might as well be left wide open for an invader the size of a spider.


Perimeter applications with Temprid® will add an extra layer of defense against callbacks. With a long-lasting residual and fast knockdown, Temprid applied around exterior openings creates an industry leading barrier to spiders.

Another tip that can make a difference the entire season is to take out the food source for ground hunting spiders. Spider prey includes crickets, roaches, earwigs and other outdoor insects. These, and others, are easily controlled with an application of Maxforce® Complete insect bait granules. Getting on this in the spring will make a huge difference when summer pest pressure peaks and will drastically reduce ground hunting spiders as well as other predators like scorpions.

Web-Building Spiders

  Web-building spiders are those spiders who use webbing as a trap to catch their prey. Many web-building spiders are very cryptic and spend their daylight hours hiding in a cozy crack or crevice somewhere very near the web. Webs can take the form of messy cobwebs to intricate nets woven with uncanny precision.

For most people, a home is the largest investment they will make in their lifetime and is a source of pride. A haunted house look covered in webs – isn’t what most homeowners are going for and could be the primary reason they have a pest control service. 
Many times a diligent technician who has spent valuable time cleaning webs with a web-dusting tool will be frustrated and surprised when that account produces a trouble call soon after the service. When webs are removed but the spider is left alive, it will rebuild a web the very next day. Often the customer will never notice the thorough job done cleaning unsightly webs.


The key to eliminating these spiders is thoroughness of application. However, there is no need (or enough time in the day) to thoroughly treat every crevice on an eave line or the entire weep screed. The key is to use the webs as a treatment guide. It is very important to make your treatment before removing the webs. An old pest control saying is very appropriate here, “If they are wet they are dead.” With funnel web and many other cobweb-producing spiders, after careful observation, you will notice a web-lined entrance to their lair where there will almost always be dead insect remains scattered around. A fine low-pressure shot of Temprid into that opening will hit them right between the eyes!


The powerful co-milled formulation of Temprid will make history of that spider and the long-lasting residual will help ensure another one doesn’t move in for the rest of the summer.


This season, use Temprid, a thorough application, and a steady hand to turn spider trouble calls into glowing referrals for you and your company.
