🏷️ Brand Names — Same Active Ingredient
⚠️ Don't buy duplicates. All products below contain amorphous silica gel (92.1%) as the active ingredient. Buying two different brands is buying the same pesticide twice — they differ only in price, concentration, and formulation type.

🔬 How It Works
CimeXa is amorphous silica gel — structurally different from diatomaceous earth (DE) despite both being silicon dioxide-based. Key advantage over DE:
- Works at low relative humidity (down to 20% RH) — DE requires 50%+ humidity to work effectively
- Ultra-fine particle size adheres to insect cuticle more effectively than DE
- 10x more effective against bed bugs than DE in controlled studies (Penn State data)
- Remains effective for 10+ years in undisturbed areas
Like all desiccants, CimeXa works mechanically — not chemically. It absorbs the waxy protective layer from the insect cuticle, causing death through desiccation. Insects cannot develop resistance to physical desiccation.
⚗️ Mixing & Application Rates
CimeXa is a dry dust — applied with a bellows duster or puffer bottle. Very fine — use sparingly.
Bed bug void/crack treatment
Very light dusting — barely visible layer
Apply with bellows hand duster to wall voids accessible via outlet covers, behind baseboards, inside bed frame voids, and box spring interiors. Less is more — a thick pile of dust will repel bed bugs rather than attract them. CimeXa works when bed bugs walk through the treated surface.
Cockroach void treatment
Light dusting in enclosed voids
Apply behind refrigerators, under dishwashers, inside electrical outlet voids, and inside wall voids via bellows duster. Excellent long-term residual in undisturbed void areas.
Perimeter dust (crawl space, wall voids)
Light coverage on horizontal surfaces
Apply in attics, crawl spaces, and basement wall voids as long-term preventive treatment. Remains effective indefinitely in dry, undisturbed conditions.

⚠️ Safety & Precautions
- Very low toxicity — silica gel has a wide safety margin for mammals
- Wear N95 mask during application to avoid inhaling fine silica particles — chronic inhalation is a potential lung irritant
- Do not apply to wet or damp surfaces — moisture deactivates desiccant action
- Avoid applying to food contact surfaces
- Keep dry — moisture permanently deactivates CimeXa

❓ Frequently Asked Questions
Q: Is cimexa silica gel safe for pets?
Follow the product label. Keep pets out of treated areas until completely dried (2–4 hours for sprays). Once dry, treated surfaces pose minimal risk to dogs and cats.
Q: Can I use cimexa silica gel indoors?
Check the specific product label — formulations vary. Baits and dusts often have indoor labeling; concentrates and granulars are typically outdoor.
Q: How long does cimexa silica gel last after application?
Residual varies by formulation, surface type, weather, and UV exposure. Indoor applications last longer than outdoor. Check the product label for re-application intervals.
Q: What should I do if exposed?
Remove contaminated clothing, wash skin with soap and water. For eye contact, rinse 15–20 minutes. For ingestion or severe symptoms, call Poison Control (1-800-222-1222). Have the product label available.
