LambdaStar UltraCap 9.7 adheres well to surface areas and is ideal for perimeter treatments around structures. Spray around the house perimeter, around windows, under eaves, door thresholds for a variety of household insects such as large roaches, spiders, scorpions and more (see label).

Mixture|Application Use between 0.2 oz to 0.8 oz per gallon of water; keep it agitated inside of sprayer.
  • Cockroaches, Crickets, Earwigs, Firebrats, Silverfish, and Spiders: Spray LambdaStar UltraCap 9.7 inside in areas where these pest hide. These areas include corners, baseboards, around water pipes, corners, attics and eaves, behind and under kitchen appliances, cabinets, under sinks, underside of drawers, doors and windows and similar areas.
  • Bees, Flies, Mosquitoes, and Wasps: See label for caution warnings for stinging insects. Spray LambdaStar UltraCap 9.7 on resting areas where these flying insects land. Suggested locations include ceilings, window screens, walls as a residual surface treatment. May be used inside and outside in garages, storage sheds and garages.
  • Carpenter Bees: LambdaStar UltraCap 9.7 is an excellent product for carpenter bees. For best results spray a course spray in areas before an infestation begins to prevent bees from boring holes in the wood. When bees have infested wood, surface applications can help control embedded larvae and bees that emerge from the wood.
  • Pantry Pests (i.e., Carpet beetle, Cigarette beetle, Confused flour beetle, Lesser grain borer, Red flour beetle, Rice weevil, and Saw-toothed grain beetle): Spray LambdaStar UltraCap 9.7 as a crack and crevice treatment to shelving in the cupboards, and storage areas after removing uncovered foodstuffs and utensils. Allow treated surfaces to dry and cover shelves with clean paper before replacing any utensils, foodstuff, or other items. Any foodstuff accidentally contaminated with treatment solution should be destroyed.
  • Boxelder Bugs, Centipedes, Millipedes, Pillbugs, and Sowbugs: Apply LambdaStar UltraCap 9.7 around windows and doors and other entry points where this pest may be found or where they may enter homes.Treat baseboards, storage areas, and other locations.
  • Cluster Flies: Early fall or late summer, use LambdaStar Ultra 9.7 before these flies are observed and "overwinter". Spray in such areas as under eaves, thoroughly on siding, around doors and windows. Pay particular attention to south-facing surfaces. Do not allow a run-off to occur. Heavy precipitation prior to frost may require retreatments to maintain protection. In winter and spring when flies become active and are emerging, interior crack and crevice and void treatments can help reduce the infestation, along with ULV or general surface application in infested attics or unoccupied lofts.

This stuff is a death sentence and invisible barrier to all insects INCLUDING wasps!!!
I'm quite allergic to wasps and researched pesticides I could use to prevent wasps from making their homes around my home. Killing wasps wasn't my main concern as I usually keep a large supply of knockdown spray on hand. However, I wanted something I could spray around the house and yard to prevent them from making nests. I tried things in the past but never had much luck. Things I found online claim to work very well but they either leave behind haze or need to be reapplied after each rainfall. This stuff doesn't have knockdown power (although I hit a couple wasps with it and they did fall down but didn't die right away) but it WILL kill any wasp that lands on a treated surface for weeks after application. My yard used to be so full of wasps during the spring and summer months that it was almost impossible to enjoy my time outdoors due to the constant swatting and being chased. Since spraying down walls, eaves, and everywhere else they land and/or build a nest, my yard is ALMOST wasp-free for weeks after spraying.

As an added bonus, this stuff will also kill just about any roach, beetle, horsefly, SPIDER, and any other insect that crosses its path. FAST.

I was a doubter before. I assumed reviewers were exaggerating before, but my allergic pansy ass decided to take a chance on this stuff and I'm so glad I did. I've reclaimed my property for myself and my family. GET THIS STUFF!

Used to treat a centipede problem in southern PA. Treated French Drains in basement and crawl space. After one treatment the problem was solved. Very effective

Great stuff thus far
Product mixes well, applies well and no wasps or bees near my deck since application two weeks ago. Wondering how long the application will last? Five stars if it holds up well.

Excellent product and custer service
This was an outstsanding do all product for multiple insects around the house. Mo more ants, mud dobbers, spiders, or roaches that came in from the outside. I have recommended this product to several of my neighbors that have had the same results.

Great Product
Kills Boxelder and Lady bugs and still killing them... Highly recomend this product!!!
Review by Possum / (Posted on 5/14/2018)
Not sure if it works on spiders...
I drenched my house top to bottom with this stuff a few weeks ago and I appreciate that it's odorless and non-staining. I didn't have an existing infestation but sprayed as a preventative measure. I've since found a couple dead firebrats and mealworm-type things here and there, but unfortunately, the handful of spiders (mostly daddy long legs) I've found in my house have all been alive and well. I've set sticky traps for them and am very careful about not leaving clutter or trash anywhere, so I'm hoping the spiders will jump ship now that the other bugs are gone.

Kills scorpions
I have tried numerous products, this is the only one that kills scorpions. Very effective,I sprayed last in the fall and it kept on killing throughout the winter. I am ordering more!
Review by wildsage824 / (Posted on 3/23/2018)
Happy with my results!
Works very well against scorpions and crickets. I apply on the footing of my house and around the perimeter of my lot along with Delta Dust. I like being in control of the quality and amount of product I apply unlike the diluted stuff the pest control companies use.

Great product
My mother was having at least one of two of the large wood roaches in her house nightly even after blowing the leaves away from around the house...so ugly! Bought the Lancaster 9.7 to keep them away...well I sprayed according to the instructions and we saw one inside the day after and since then none!

Great product
It works! Roaches and palmetto bugs are gone, and that's incredible for Florida. Fast shipping and competitive pricing, I will purchase again.
Review by Rancher Man / (Posted on 12/11/2017)
I have dealt with boxelder bugs swarming my house and totally covering it in the fall for years. I was willing to try anything (and I have in the past). I thought the price was high but like I said, I was willing to try anything. I got the product, mixed up a gallon of spray which took hardly any of the material, and began to spray the sides of my house. OMG! The boxelder bugs started falling off my house in droves. Within a short time about half of them had fallen and the rest were moving slowly. I left them alone for the evening. The next morning about 90% of them had made a carpet of dead bugs on my deck. It's been about 2 weeks now and they are still coming and dying. This product is wonderful!

Worked awesome on boxelder bugs
Very pleased with results. Wanted to paint house but had huge boxelder problem. LambdaStar knocked them down and made the house paintable!

Great for Cluster Flys
Had a terrible cluster fly problem. Thousands in the cabin. Even in the Winter when it was 20 below zero outside, the flys would come out once the building heated up. Used this product and almost overnight, the cluster flys (and Asian Lady Beetles) were virtually gone!

Sprayed on the South and West facing wood siding, and it worked like a charm.

This shit is crazy powerful
I used to see 1 or 2 roaches in my back yard. One day i sprayed this product on the wall on the spread mulch in my garden and the results were astonishing. After spraying, next days i saw tons of roaches fumbling around and dying. When I say ton, i really mean it. it felt like a swamp of roaches was attacked by this pesticide. will give A++ to the scientist who came up with the formula.

Very powerful, works great!
Very powerful, works fast! Had a problem with a hatch of black widows. This stuff killed the spiders, and their food sources roaches/crickets everything. The residual effect lasts well after application. Very impressed. The bottle will last me for years with the minute amount needed to dilute in water.
Review by Mallard702 / (Posted on 10/12/2017)
Just buy it already.
This. Stuff. Works.
I had a terrible spider problem when I discovered this product. After use, no more problem. It works on everything I have sprayed it on....ants, spiders, sow bugs, earwigs, beetles, crickets, even wasps. Careful though if you have bees, we need the bees.
My mix is a bit different. I do one full ounce initially, say spring, and then the recommended .4 ounce thereafter. Works like a charm and I will never use anything else. I also tell anyone I can about it, am sure you have sold a few bottles on my recommendations. Bought my second bottle this summer, previous one lasted two years, 24 applications of varying doses, depending on the problem and the precipitation.
The best kind of bug is one laying on its back writhing in agony, this stuff accomplishes that and more.....the word is out in the bug world....keep away from my house.

Really works
We have horrible scorpion problems in AZ. I was doubtful that this would work, with such a low concentrate needed to mix with a water...but boy...did it work ! I tried some many sprays...this works.

This is the BEST!
After being pointed to this product from a professional exterminator..we will NEVER go without. We were unaware we had a major infestation of scorpions after closing escrow on our recently remodeled home. It was virtually inhabitable. Until UltraCap that is. I'm not sure how or why it works, but it has saved my sanity. I tell everyone I know about it! We sprayed every inch of the house every 14 days for two months to start, and then tapered back to just the perimeter every 30 days. We are so happy we found this product and the price is so fair. A 16oz container lasts us 36 months and we spray all 12 months of the year (desert environment).
