Funnelweb spiders are a spider species that commonly venture indoors and make themselves at home. If you haven’t gone into your attic or basement for a while and find a load of cobwebs to navigate through, it’s safe to assume you have a funnelweb spider present. The web-making of this spider can create a messy appearance in your home and make it look like a haunted house on Halloween.

Funnelweb spiders are versatile when it comes to the places where they enjoy living. They have been known to spin webs in grass, bushes, wooded areas, gardens, small caves, corners of buildings, under rocks, and in dark areas inside homes. Their diets consist of small insects which they trap inside their funnel-like web. You can usually tell you have an infestation of Funnelweb spiders by finding webs around your home.

If you have an issue with funnelweb spiders invading your home, our DIY funnelweb spider treatment guide can help. Our pest control experts have compiled the step-by-step instructions below, which are guaranteed to eliminate this spider species quickly if you follow the directions carefully and use our top recommended products.

Identification

The first thing you should do in any pest control plan is identify what exactly you are dealing with. Carless identification can lead you to use the wrong treatment methods, costing you time and money. While many families of spiders are referred to as funnel web spiders, this DIY guide will focus on North American spiders in the Agelenidae family, including common grass spiders and the hobo spider. 

• While multiple species of funnelweb spiders vary in appearance, they are generally brown or gray, have very hairy legs and body parts, and have markings that are darker in color than the rest of their body. These spiders have eight eyes that are roughly the same size. 
• Ranging from about 1/5 of an inch to about 3/4 of an inch in body length.
• The distinguishing trait of funnel web spiders is a tail-like structure on their backside, which shoots out web silk used for spinning their webs. They are called funnel web spiders because their webs look funnel-shaped, which they use as both a mechanism to trap insects and to create a hiding space to ambush bugs to eat. For example, grass spiders have elongated thoraxes and long tail-like structures at their rear ends known as spinnerets. House-infesting tunnel weaves have rounder thoraxes with a more patchy pattern.

Inspection

Inspection is the next phase of any good pest control plan. Once you know what your pests look like, check around your property to confirm the funnelweb spider prescence or find hotspots of activity.

Where To Inspect

Funnelweb spiders enter homes to look for insects to eat and hang around dark corners on their funnel-shaped web, which is rarely frequented and out of sight, where the spider waits for its prey. For this reason, take a close look at your garages and sheds. Clutter in basements and attics are also a perfect place for spinning webs. Other spots where webs can occur are on fallen branches, rocks, underneath eaves, within bricks, and outdoor lighting.

What To Look For

Aside from the spiders themselves, you'll want to look for areas where their funnel-shaped cobwebs have been formed, as these are areas where they are most active. Also, note any entry points spiders, or other pests can use to invade your home, as the high presence of pests may indicate this. Be cautious, as funnel web spiders will bite if disturbed. The bites from North American funnel web spiders are not lethal but can still cause mild, lasting pain.

Treatment

Funnelweb spiders are not a considerable threat compared to other more notorious spiders, but they can be annoying with the web-spinning they do. To successfully drive them out of your home, you will need to treat both the spiders themselves and their food source, insects.

Using a Cobb Webb Duster to wipe away and destroy spider webs and spider eggs, a treatment of Supreme IT insecticide, and laying out glue traps to capture the pests will do the trick, along with exclusion and decluttering practices. 

Prior to chemical application, remember to read all product labels, follow application instructions, and wear personal protective equipment to stay safe. 

Step 1: Declutter

Reduce the clutter in and around the home. The more junk you have lying around, the more likely a spider will make itself at home. Spiders like hiding under a bunch of junk in storage areas, in dense areas where they can hide, or in attics where they can live undisturbed and secluded.

Tidy up your home, get rid of unnecessary things you are hoarding, and especially clean up your storage spaces, such as closets, the garage, and the basement/attic.

Step 2: Knock Down Cobwebs with Cobb Webb Duster Head

If you see any cobwebs during the cleanup, we advise you to knock them down using a duster head such as the Cobb Webb Duster Head. The Cobb Webb Duster head has special small nylon bristles on its head, which are perfectly designed to remove funnelweb spider cobwebs and any spider eggs they've laid.

If cobwebs are located in hard-to-reach places, you can attach the threaded end of the Cobb Webb Duster head to an extension pole to get better reach and knock the cobwebs down.

Step 3: Exclusion

Address any entry points you have found, such as cracks, gaps, and holes, where spiders and other pests may enter your home and surrounding area. Tight cracks and crevices may be filled with caulk, while larger voids may need to be stuffed with copper mesh. 

You may also need to repair any torn screens of affix brush or repair rubber seal on doors and windows. 

Step 4: Insecticide Treatment

Indoors, we recommend treating all your baseboards, around windows and doorways, and any other cracks or crevices where you think funnelweb spiders might be entering or hiding with Supreme IT Insecticide.

Supreme IT is a professional-grade insecticide concentrate labeled to control more than 70 pests, including spiders. It is especially effective because it kills and repels insect pests and has a residual for up to 90 days.

To start, measure the square footage of the area of your home you wish to treat to determine how much Supreme IT you will need.

For spot treatments, apply 0.33 to 1 fluid ounce of Supreme IT per 1 gallon of water to cover 1,000 square feet. 

Using a 1-gallon pump sprayer, fill it about halfway with water, add 1 fluid ounce of Supreme IT, and then fill it the rest of the way to the 1-gallon mark.

Screw the lid tight and shake the sprayer to mix the product well. After a few pumps of the handle, you're ready to spray.

Use a coarse, low-pressure spray to spot-treat where pests hide. First, the mixed solution should be applied indoors as a crack and crevice treatment around entry points like doors and windows. This includes baseboards, around water pipes, behind and underneath appliances, and wherever pests may hide. You will also need to treat in attics, basements, and garages. 

Outdoors, apply our solution as a perimeter treatment by spraying alongside your home's outer perimeter, 3 feet up the structure, and 3 feet out. When complete, allow the solution to dry, which will then create a residual that lasts up to 90 days to treat funnel web spiders and 70 other types of pests. 

Step 5: Set Up Glue Traps

After chemical treatment, we suggest you set up glay trays such as Solutions Pro Glue Traps to monitor for further funnelweb spider activity. This will easily trap insects that slipped by your Supreme treatments, diminishing the spiders' food source.

Simply remove the trap's waxy paper seal and lay the trap flat and flush against the wall near where you have seen pest activity. Make sure the trap is out of reach of children and pets. 

If you, a child, or a pet become stuck on the Solutions Pro Glue Traps, you can use cooking oil to loosen the traps' adhesive. 

Prevention

Prevention is essential to keeping the funnelweb spider population and activity in check. To prevent funnel web spiders from returning, refer to the following prevention methods.

• Practice good housekeeping, implement a regular cleaning routine, and organize your storage spaces. These will do wonders in preventing spiders from stepping foot in your home again.
• Address any moisture issues you may have indoors. Pests are attracted to moist rooms, so repair any leaky pipes or air conditioning issues, drain any standing water, and dry your sinks out every night.
• Rake the lawn regularly to ensure any debris is removed to prevent hiding places for funnelweb spiders. Keep the firewood properly stacked away from your home's foundation to remove these conditions further.
• Continually retreat with Supreme IT as a perimeter treatment outside your home to discourage Funnelweb Spiders or other insects from returning. Supreme IT has a 90-day residual effect, so it is recommended to spray quarterly to keep pests away year-long.
