I feel like every day I kill two spiders in the exact same spot as the ones I killed the day before.  I always find them where the wall meets the ceiling on a very specific wall inside my house.  They look like they’re dead or sleeping.  I kill them before I go to bed, and then in the morning there are two more there in almost the same spots! I don’t *think* there are webs there.  Why do they keep coming back to the same spot, and why in groups of one or two?

Spiders will be hard at work creating new nests every spring. We see this all over so what you are experiencing is no surprise. They love to build these nests in two main locations: baseboard floor molding and up high around crown molding. Outside spiders commonly nest around windows, door frames, attic vents and under eaves. My guess is you have had some living in these areas over the years and from there they’ve migrated inside the home.

Once they get inside, they’ll live in attic spaces, basements and crawlspaces or directly enter living areas from the outside. In homes which provide good attic spaces, we find spiders commonly appearing up high, along the ceiling perimeter, much like you describe. And since web building spiders don’t much like moving around, they’ll use the first location they find when migrating. My guess is a new supply of spiders is entering your living spaces every day or two and when they find vacant areas (where you just killed 1-2), they decide to grab and use this space. I also suspect more are active but might be missed. The ones up high are probably the easiest to see which is why they seemingly always appear in this one location.

Why they choose this specific location is a bit more complicated. In most cases it’s due to wind and light levels. I know there probably isn’t any “wind” in your house but remember, to a spider any air movement is wind. Web makers are trying to catch prey and where air is moving is where they expect food to be present. Ceiling lines are great locations for this – as are flooring baseboards – which is why these two areas commonly see activity.

At this point I suggest some control measures put in place which will prevent this problem from happening. If you review our SPIDER CONTROL ARTICLE, you’ll learn several treatments that can be done which will help. For your situation, I’m thinking you should start on the outside with a good barrier application. Apply some DELTAMETHRIN all the way around the home focusing your attention on the spots where sopiders are likely to enter. These will probably be under the eaves, around windows and by soffit vents. Attic vents are another great entry point so don’t rule them out. The key to your outside treatments is get up as high as you can reach as all areas of your home are likely entry points.

Inside the home be sure to treat attic and crawl spaces if you have any. You don’t mention this but my guess is you do and I also suspect these areas are involved. A good dusting with the DRIONE DUST will take care of this area and treatments last 6-12 months so you’ll achieve long term protection from your effort.

Lastly, in the living spaces, apply the PT-PHANTOM AEROSOL. I find this works the best in the home mostly due to it being odorless and dry to the touch when applied. I have hardwood floors so spraying a liquid or most any aerosol can be messy. But the Phantom goes on dry and is invisible when applied properly. For me this is important as I get to treat my house without making a mess. And I find treatments last 1-2 months. In the spring I do a treatment March-April-May and then I don’t find any more as long as I stay on it every 45 days till Christmas. Inside the house spiders can remain active all year long but we do find treating January and February isn’t needed. For you the Phantom would be ideal for treating up high where you seeing a recurring problem. If you treat the area monthly, you won’t see any return and combined with the other treatments I listed above, you should be able to stop them altogether.

I’m wondering if I can spray the foundation & perimeter of my house for Spiders – using Deltamethrin or LAMDA-CYHALOTHRIN and spray the same areas with Conquer EC.

Is it OK to spray over one insecticide with another? I have problems with Spiders and Camelback Crickets and I’d like to know if I can use both before I buy the products.
Thank you.

As a general rule you don’t need to mix adulticides. All three chemicals you mentioned are good for the pests you’re targeting. If I had spiders and crickets, I’d go with just the DELTAMETHRIN as it will handle all your needs fine. Odorless and long lasting, it’s all you’ll need this season. When you need to get a refill, you might consider changing but if you don’t have any problems at that time, you can stick with it for maintenance for many years. Excellent product for sure.

I found your company with a google search.  We have a 55’ ceiling.  Do you have a web remover that will work at that height?

Or any suggestions as to where I could look?

Thank you.

As I’m sure you surmised from our online catalog, the longest WEB REMOVER we have is our 30 FOOT MODEL. People have used this to reach over 30 feet high and I don’t know if one is available any longer. There are obvious hazards and problems constructing these poles and I just don’t think it’s cost effective for the companies who make this line of equipment.

I do know we have suggested some work around’s that have helped people in the past and maybe one of these ideas will help you too. The two we’ve suggested before involve positioning yourself on a high platform, possibly a ladder, and from there using the Web Remover. In one scenario we had a homeowner reach over 40 feet while working from a ladder that was about 10 feet tall. In another the people had a scaffolding platform up almost 20 feet high and from there they were reaching close to 50 feet up. I’m guessing if you have any maintenace done to lights or something else up near the ceiling there could very well be something already at the location that could help achieve this height.

Let us know if you have other questions or concerns; we’re just a phone call away at 1-800-877-7290. Remember, the 30 foot pole we have listed has a threaded end and will readily accept paint rollers, window cleaners and a wide range of tools making it handy for anyone needing to maintain a large or tall building.

I have a big problem with spiderwebs in my South Florida screened in pool area.  They seem to like to make their webs on the screens covering the pool and porch areas.  Is there any product I can spray or apply to the screens to repell them?


Areas with moisture, light and structure are ideal for web making spiders. All of these components will attract flying insects many of which are prime food for spiders. If you aren’t doing regular pest control in and around this area, I would expect all kind of pest activity since it’s such a prime spot for what insects need to thrive. Based on what you’re reporting, it sounds like the local pests are finally figuring this out.

The good news is you have lots of options to stop both the spiders and any other pest like roaches and ants which are sure to get active in this area if it’s left untreated. I’d say to start with the DELTAMETHRIN. It’s odorless, easy to mix and treatments will last 2-3 months. Apply it as a light fan pattern spray using a good PUMP SPRAYER over all surfaces where you see webbing or activity. I also suggest you treat around the home focusing in on the foundation, windows and other points of entry.

If you start seeing activity inside the home, install some SPIDER TRAPS to start. They do a good job of catching foraging pests and can alert you to problems you may have otherwise overlooked. If activity is noted, the Deltamethrin can be applied in this area as well as the BAYGON AEROSOL. All these products can be seen on our SPIDER PRODUCTS PAGE. If you have further questions, give us a call on our toll free at 1-800-877-7290.

Hi, i appreciate your site… it is very informative.  Read your spider control article and have a question regarding deltamethrin and Lamda-Cyhalothrin.  Are there any particular differences between the two?  For example, is one better suited for a specific type of treatment/insect… or are they about the same?  We plan to spray the interior of our house with one of those (were thinking cyonora), and use a dust in our crawl space.  Our main concern is reducing the number of brown recluse spiders.

Thanks for any advice/clarification!

There is little to no difference in overall performance from either of the actives you listed. Both have low to no odor, both work well on a wide range of pests and both can last 2-3 months. Overall they are excellent choices for use in and around the home. When combined with the other materials we have listed on our SPIDER CONTROL PRODUCT PAGE, I’m sure you’ll be satisifed with the level of pest control you’ll be able to maintain around the home. When used throughout the year, you should be able to keep a pest free environment if either is employed. Should you have further questions, give us a call on our toll free 1-800-877-7290 and Thanks for the great feedback!

I had my house sided with vinyl siding a couple years ago.  There is some type of spider that likes the nooks and crannies of the siding, also the soffits and door frames and makes webs that trap all type of insects and leave droppings, etc on my siding.  I am looking for a spray that I can apply that won’t stain the siding and will take care of the spiders.  What would you recommend?  I also plan on purchasing one of your spider removal brushes.  Thanks!

Vinyl siding does have  a tendency to attract small insects and promote algae growth just inside the overlapping sections. Spiders will eventually find the activity and move in hoping to harvest some of the insects in the area. There are several sprays we have which can be used to stop both the insects and the spiders. Though none of them will stain, some of the wettable powders can leave a visible residue which can be seen on dark surfaces. If you have dark colored siding, go with the CYPERMETHRIN or the DELTAMETHRIN. Both will dry invisible, work well on spiders and not hurt the siding in any way.

We also recommend taking down any webs you find around the home so the use of a WEB REMOVER can really help. The best procedure is to first remove the webs and then do a good treatment with either the Cypermethrin or Deltamethrin immediately afterwards.

Since spiders will many times nest up under the eaves and soffits, it’s important to treat most of the siding on the home. This will require a lot of product to be applied so expect to use 3-4 gallons of finished spray per treatment.

Lastly, vinyl siding has a tendency to promote mold and algae growth. For this reason we recommend spraying it at least once a year with a mold killer/inhibitor like MOLD AND ALGAE KILLER. This will indirectly stop the insect activity which in turn will cut down on the spiders too. If you note a lot of moss, mold or algae growth, take care of it and this in turn will help cut down on all the other insect activity including the spiders.

Dear Sir,

I pressure wash homes for a living and I have one home in particular that has a really bad spider problem. The real problem for me isn’t the spiderwebs but instead it is some kind of jellied snot balls on the walls that will not come off easily by pressure washing alone. They can be pulled off easily by hand but not by cleaners and pressure washing. I have tried a multitude of products with no real success. First, are these little balls of jelly from the spiders? Second, what will make the turn loose? Any help would be greatly appreciated.


I’m not sure what it is that you are finding on this home. Spider eggs are usually small, round and slightly smaller than a marble. Generally they are quite dry, even outside, and normally do not take on the characteristics you describe. But there are several other insects which will “nest” on homes. These nests are more likely pupae casings and the more common insects that use homes for this include bagworms and all kinds of moths. Larvae from these insects will leave where they were born and travel to a good “roosting” site where they spin a cocoon and undergo metamorphisis. Have you tried opening up any of these jellied snot balls? My guess is they will harbor some kind of molting insect which is using the structure instead of nearby trees or other natural structure on which to go through this stage of development.

To help deal with the issue, there are two things you should consider. One would be a good tool to remove the sacs and the other involves some sprays to help prevent the invasive pest from returning.

To help take down the sacs, I suggest getting a SPIDER WEB REMOVING TOOL. You can get this configured in several lengths including the one that will reach over 30 feet high. This would help remove spider webs along with these annoying “snot balls”. It’s definitely handy and should eliminate the need for using a ladder most of the time.

To prevent the jellied snot balls from returning, treat the house with WEB OUT. Though formulated with spiders in mind, this totally “organic” spray will repel spiders and other insects from the structure. Use it quarterly and you should be able to keep larvae stages off the building thus avoiding the jellied snot balls (most likely pupae cases) altogether.

If you find the Cobweb Eliminator isn’t strong enough, treat with the EXEMPT ECO IC or BIFEN. The Exempt does not require an EPA number so it’s not a real pesticide; the Bifen would be the strongest option here and should provide 2-3 months of protection from any pest that would forage onto the structure. By treating the sides of the home with the Bifen, you should be able to stop any pest from foraging onto it so no new nests would develop.

If you have further questions, please give us a call at 1-800-877-7290 and someone in technical support should be able to further advise.

I just ordered one of these spiders. Do they make a noise when dropping down? We want to use for Halloween Decoration.

Thanks, M.D.C.

The Attack Spider is mechanical and has two moving actions. The first is the string release. This causes it to drop down about 2.5-3 feet. A slight sound can be heard when the release happens. Next, it “rewinds” the string which makes a sound during the entire process. Other than these sounds, there is no “scary” sound or noise it has built in. To better understand what I’m describing, you can hear it quite clearly in the following video.

Your Attack Spider would make a great Halloween decoration. Is it safe for so use?

Our Mechanical Crawling Spider is perfectly safe for this use. It’s basically nothing but a wind up toy which is powered by batteries. About the size of a paper plate, most people use them as decorations on their front door, porch or railing. When children come close to it their movement can set it off and it will provide a great scare for sure! We sell a lot of them for this use and it definitely will provide some fun at Halloween. This video shows it in action..

I have an unfinished basement where folks almost never go. Part of it is dug out to about 5” tall, while most of it is crawl space. I have spiders that look like brown recluse but I’m not interested in getting close enough to tell.

I need an eco-friendly (no smell, or low smell) product that can be used over a wide broad area. I would estimate the basement to be about 1,000 sq. ft.

What would you suggest?

If you review our online article that lists several products for INDOOR SPIDER CONTROL, you’ll find both DELTAMETHRIN and LAMDA-CYHALOTHRIN are mentioned. Both these products are virtually odorless and very effective on spiders including brown recluse. I would recommend spraying the entire area with either and doing this once a quarter to prevent reinfestation. These products must be applied with a good PUMP SPRAYER and I would recommend treating the outside of the home too, around the foundation, to prevent them from getting inside. Again, these products are what many professional companies use so they are as good as it gets when it comes to performance.

Another product I have bound to be quite effective on spiders is the PHANTOM AEROSOL. This virtually odorless aerosol can be sprayed over any exposed area and it’s unique “dry to the touch” spray means you won’t see any trace of it when applied properly. I use this on my boat to keep spiders from making spiders and you can’t tell I have sprayed just seconds after I do. It seems to go on dry and doesn’t hurt the finish or leave any visible residue unless you keep spraying in the same spot and even then, it dries quickly. My boat is kept outside so it’s subject to the wind, rain and other elements. Still, the treatments seem to last upwards of 1-2 months even in this environment. Inside the home I’ve used it for spider control and get 2-3 months of residual so it’s long lasting as well as effective.

Lastly, we do have a product called HOUSEPLANT INSECT KILLER which is organic. We commonly sell it for use on indoor potted plants. It’s more geared toward mealy bugs, thrips, aphids and other plant living pests. But it is organic and it will kill spiders so this would be the last option that’s viable. Keep in mind this won’t last long residual wise. In other words, you’ll need to apply it 1-2 a week so compared to the other options, it will be the most short lived.

Here is a photo of a brown recluse spider that was killed using our hand HAND HELD ZAPPER. This tool is handy to have and can handle most any insect you might encounter. Spiders, bees, wasps, roaches or mosquitoes are just a few of the more common species targeted with this device.

We used to have a brown recluse infestation (75 spiders caught in 6 months!) but have not seen any for years due to a regular spraying program.

I used to use Ficam W 76% Wettable Powder to spray the baseboards and under counters in our home. I had stocked up on Ficam W before it went off the market, but just now I have run out. I also used FICAM dust before it went off the market, but now I use Drione dust with a B&G Sprayer I bought from your firm a long time ago.

Ficam worked great but it does leave a white residue on the brown baseboards.

What product do you suggest to replace Ficam W with for spraying in a pump sprayer the baseboards inside the house and under sinks inside, etc.? Does that product get into the atmosphere or does it stay on the baseboard like Ficam W did?

And what product outside in a pump sprayer—delta or lamda?


If you review the products we have listed for BROWN RECLUSE SPIDER CONTROL, you’ll see the first two listed are DELTAMETHRIN and LAMDA-CYHALOTHRIN. Either of these would be fine. They both work well, have no odor and will dry invisible.More importantly, they work well for any spider including Brown Recluse.

If you need more dust, the DRIONE would be a good replacement.

Outside, the BIFEN GRANULES work well on any spider and should be applied to the turf. Spray the house with either the Deltamethrin or Lamda-Cyhalothrin and you’ll be able to keep any pest out of the home.

Many spiders are clearly visible during the day. Web making spiders can be seen literally hanging around. However, there are many that are shy and reclusive. Brown Recluse Spiders are such a spider. During the day or in any room where there is bright lights, they will make themselves scarce. They don’t like to be seen and are typically sensitive to light. They like to move under flat objects, into cracks and crevices and up under siding. These locations will be the key to solving a local infestation and treating them well will be important.

Filed under Where to Treat by  #


Which brownrecluse spider spray is the best? We get asked that question a lot. There really isn’t any one spray that’s best. In fact, it’s a combination of “tools”. The tools include some sprays but the real key is where you apply them. Even the best products won’t help much if they’re not applied where it matters most. Since each infestation is unique to itself, it’s important to survey and understand the problem at hand. Inside infestations will need some Baygon and Lamda-Cyhalothrin. Be sure to set up some traps in rooms where activity is either seen or suspected to be active. More specific details are explained in our spider article here.
