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.

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.

Brown Recluse Treatments inside Homes

Treating inside a home for brown recluse spiders will many times be the only way you'll be able to knock them out once and for all. Once established inside, brown recluse spiders can be difficult to control. They naturally hide and avoid bright light making key locations difficult to identify. Brown recluse spray should be directed toward the floor boards and residuals should be applied where there have been sightings. Many people get worried about spraying inside but the bottom line is you have no choice. Brown recluse spiders present a hazard to anyone or animal and should not be ignored!

Spiders will many times start to nest up under house siding. This location provides a great place for them to hide from the elements, predators and other dangers. Be sure to either dust or spray up under siding which has spider activity if you wish to prevent further activity and inside the home penetration.

Spider droppings can become quite a mess. They will accumulate below nest locations and can be quite large even when produced from relatively small spiders. Cleaning these droppings will enable you to readily identify new infestations as well as help prevent any damage this highly acidic waste can cause. The best product for the job is WEB OUT. It's federally Exempt because it's made from all natural, food grade actives. More importantly, this product actually works. In fact, it works great.

Web Out can be used to remove spider droppings. Simply spray a light mist over the droppings and let it sit for 5-10 minutes then wipe away with a moist paper towel or rag.

Web Out will remove webs. Lightly mist unsightly spider webs, let the treatment sit for 5-10 minutes and the webs will easily wipe away. This is especially helpful when used on our WEB REMOVER.

Web Out can also be used as a spider killer. Any spiders sprayed with Web Out will quickly die.

And Web Out is safe to use on the lake, ocean or other water areas where traditional products can't be applied without fear of contaminating the water. Treatments can last a month or longer depending on where it's applied.

Removing old spider webs should be done whenever possible. This is particularly important in rooms which don't have people in them frequently. By removing old webs, you'll be able to better tell when there is new activity.

Removing spider webs will make the overall spider control program that much more effective. Spider webs are fundamental for many species of spiders and if their weave is interrupted, damaged or removed, they will work to restore things to normal as soon as they can. This means they will be active and many times this activity will cause them to get exposed to your treatment. It will also cause them to use a lot of energy which in turn can lead to lowered levels of active ingredient needed for control. The bottom line is removing spider webs both enhances your treatment and will tend to hasten positive results. Use one of our web removers for hard to reach webs and be sure to spray the area with one of the residual products we have listed in our product section.

Treating a Baby's room or any room where people spend a lot of time needs to be done with caution. We always suggest to first set out some glue traps to monitor the problem to see just how extensive it really is. Once the level of activity is known to some degree, a treatment plan can be put in place which will both reduce the spiders and not put anyone at risk. Give us a call for specifics on  how to treat your sensitive room to get spider control.

We get this question quite a bit. The answer isn't always clear which means that many times the best thing to do is cover all bases.

If you're seeing spiders in the home, go ahead and set up some SPIDER TRAPS in any room where you see activity. You should also do some crack and crevice work with some BAYGON AEROSOL or the odorless and "dry" PT-PHANTOM. If the spiders are merely moving in from the outside this should keep them under control for 1-2 months per treatment. But if they reappear sooner, you probably have them coming from your attic, basement, crawl space or outside home exterior.

If you think they're coming from the basement, crawl space or attic, consider using some PYGANIC DUST for long lasting protection. Most homes only need to dust once a year to keep these areas well protected.

If you believe the spiders are migrating in from the outside, an exterior program will be needed. This should include foundation spraying with the CYPERMETHRIN or the LAMDA-CYHALOTHRIN. Be sure to spray up the siding special attention to windows, soffits, gutters, porches, decks, basement windows and other routes of entry. In most cases a good exterior treatment every 2-3 months will keep the spiders off the building.

Lastly, if you see spiders out in the yard and suspect you have ground nesting species active in your turf, apply some BIFEN GRANULES every 2-3 months. This product is very active on most pests and treating the yard 2-3 times a year can really help keep all insect invasions minimized.
