Lab · Crew picks
The gear the crew actually runs.
What members of the LTK Discord say about the tools on their trucks — the sprayers they swear by, the ones that burned up in three weeks, and the cheap fixes that save a day.
Backpack and hand sprayers
The tool on every truck, and the one the crew argues about most.
(opens the product page in a new tab)Image: LESCO / SiteOne Lesco 4-gal electric backpack
Ranked #1 of the 6–7 backpacks one member has run: Lesco, then FlowZone, Birchmeier pump, Birchmeier electric, B&G 2-gal pump, Ryobi, and Tomahawk last (burned up in 3 weeks). The adjustable tip handles cracks and deck boards. Downsides: the standard battery lasts about half a week (the larger one is ~$100), there is no pin-stream tip, and the holster breaks if it catches in a tailgate.

(opens the product page in a new tab)Image: LESCO / SiteOne Lesco / Smith backpack
Rated the most comfortable backpack sprayer they have owned.
LTK member · Sep 2026View product (opens in a new tab)
(opens the product page in a new tab)Image: FlowZone FlowZone Typhoon 3 / Storm 2
Called the industry standard. One member runs 7–8 on shared batteries. Tips: pressure-washer fan tips make cheap fan nozzles, fan spray beats cone, and pulling the wand to use the green tip speeds up 3-up/3-out perimeter sprays.
LTK Director and members · Jan 2025View product (opens in a new tab)
(opens the product page in a new tab)Image: FlowZone FlowZone 1-gal handheld
Called the best interior sprayer by far. Worth one on every truck, and it runs on the same battery as the backpacks.
LTK member · Jan 2025View product (opens in a new tab)
(opens the product page in a new tab)Image: FlowZone FlowZone Vortex mosquito attachment
About $350. Quiet, with better range of motion than a blower. Rated 70+ minutes (32 on boost); the attachment battery dies before the backpack’s.

The $10 louvered circle piece is a must, or you only get about two-thirds of the height.

(opens the product page in a new tab)Image: Ensystex Accuthor 1-gal stainless spray can
$489 list, with a pressure-relief pull valve. The hose and wand connection is different from B&G. Was free with 5 cases of Bithor SC under an Ensystex promo that ran through August 2026.

Airfog has a good pressure-relief valve and a wide opening, but a skinny collar O-ring.

The worst of the ones this member has run. The battery isn’t protected from rain.

Foggers, dusters and aerosol delivery
For the jobs a sprayer can’t reach.

Exclusion and hardware
What goes into the gap, and what it costs to put it there.
(opens the product page in a new tab)Image: Burrtec Burrat Samurai Armor door sweep
Replaceable brush and cheaper than Xcluder. Selling a yearly brush replacement adds recurring revenue.

Anticimex SMART drew mixed reviews from techs. Bell IQ is Bluetooth, so you have to be nearby, and it is modular with Protecta and T-Rex. Owl Sentry does automated deratization.

The NCSU/NOCS SPERT field scope (profits fund NCSU extension). On a budget, a ~$10 jeweler’s loupe or a clip-on phone macro lens. Put a dime in the shot for scale.

Chemistry talk
What the crew reaches for, pest by pest. This is technique talk between licensed pros, not a treatment recommendation.
German cockroaches
- Advion WDG + Tekko Trio, or Phantom + Tekko Trio.
- Baits the crew rotates: Advion Trio, Vendetta Nitro, Ultimatum, Vanecto (a newer mode of action).
- Let roaches “detox” from repellent residues before expecting them to take bait.
LTK members · 2025–26
Ants
- Optigard gel, Alpine WSG.
- Stop baiting when the soil cools; liquid into the nest works best in cold months.
LTK members · 2025–26
Spiders
- Onslaught FastCap, Web Out, IGRs.
- Treat the source and fix entry points, not just the room where they’re seen.
#the-hive-mind · 2025–26
Rodents
- Selontra (cholecalciferol), discussed for its lower secondary-poisoning risk.
- Also in use: Rodenthor, First Strike, Resolve, Contrac, Cad3t.
#the-hive-mind · 2025–26
Stinging insects
- Aerosol or foam, then remove the nest.
- Treat old nest sites to mask the pheromone and discourage rebuilding.
