A rotation partner for bed bugs
The label markets it as a non-repellent and a rotational partner for bed bug control. Many bed bug populations resist pyrethroids (IRAC 3A), so a Group 4A product offers a different mode of action.[1][2][3]
Where it is used
For bed bugs, applicators treat bed frames, box springs, empty dressers and closets, luggage, carpet edges, headboards, moldings and wallpaper edges. The label prohibits applying it to mattresses.[1]
For ants, it goes into cracks, crevices and voids around doors, window frames, sinks, pipes and attic vents.[1]
When treating homes, cover or clean food-contact surfaces and utensils, and apply only to the point just before runoff, never letting it drip.[1]
Don't use it in outdoor residential misting systems or in occupied classrooms or patient rooms.[1]

|---|---|---|---|
| Alpine WSG Water Soluble Insecticide | Indoor cracks, crevices, voids and spot treatments | Ants (10 g), bed bugs (10 to 30 g), spiders, pillbugs and other crawling pests (30 g) | 10–30 grams per gallon of water[1] One gallon of finished dilution treats 1,000 sq ft; 1 tablespoon of granules is about 10 grams. 10, 20 and 30 g/gal make 0.1%, 0.2% and 0.3% dilutions. |
How to apply it, step by step
1. Protective gear
- Wear a long-sleeved shirt and long pants, socks and shoes, and chemical-resistant waterproof gloves (such as natural rubber); it causes moderate eye irritation.[1]
- Take the gloves off carefully (wash the outside first) and wash your hands before eating, drinking or using the toilet.[1]
2. Before you spray
- It is toxic to bees and stays toxic on treated surfaces for more than 38 hours: don't spray blooming or nectar-producing plants that bees may visit, and keep drift off hives and flowering areas.[1]
- It can leach to groundwater where soils are permeable and the water table is shallow, and it is toxic to aquatic invertebrates: keep it off water, out of drains, and don't spray when wind favors drift.[1]
- Never apply it to people, their clothing, mattresses or pets, and keep water-based spray out of outlets, conduits and electrical boxes. It gives no instant knockdown.[1]
3. Mixing
- The label measures in grams per gallon of water: 10 g makes 0.1%, 20 g makes 0.2% and 30 g makes 0.3%. One gallon of finished spray treats 1,000 sq ft.[1]
- Ants: 10 g per gallon. Bed bugs: 10 to 30 g. Cockroaches, crickets and millipedes: 30 g. Fleas: 10 g. Use the lower rate for maintenance and the higher rate for heavy infestations.[1]
4. Applying
- Indoors, make spot, crack-and-crevice or void applications where the pests hide or travel: around doors and window frames, under sinks, around pipes and in pipe voids.[1]
- For bed bugs, treat bed frames, box springs, the inside of empty dressers, closets and luggage, carpets, drapes, furniture, headboards and wall moldings, but never the mattress.[1]
- For fleas, treat rugs, carpets, floors, upholstered furniture (under the cushions) and pet beds; for wasp or yellowjacket nests, soak the nest and the area around it, usually about half a gallon of mix.[1]
- Keep the applicator tip in the crack and spray in short bursts, avoiding drips and runoff.[1]
5. After you spray
- Keep children and pets off treated surfaces until the spray has dried.[1]
- Report any bee kill to your state pesticide agency or the National Pesticide Information Center.[1]
First aid
- In the eyes, hold them open and rinse slowly and gently with water for 15 to 20 minutes, removing contact lenses after the first 5 minutes, and call a poison control center or doctor; BASF's emergency line is 1-800-832-4357.[1]
Storage, spills and disposal
- Store it in a cool, dry place away from heat or open flame, away from water, food and feed.[1]
- Don't reuse the pouch: put it in the trash or recycling when empty; for a partly full one, call your local solid waste agency, and never put product down a drain.[1]
From the safety data sheet
- The granules are white and odorless and contain 40 percent dinotefuran; the SDS lists the product as not flammable, though its dust can form a combustible mixture in air.[4]
- The SDS classifies it as possibly corrosive to metals and very toxic to aquatic life with long-lasting effects, so keep it in its original packaging and out of drains and surface water.[4]
- If it gets in the eyes, rinse them under running water for at least 15 minutes with the eyelids held open; if swallowed, don't induce vomiting, but rinse the mouth and have the person sip water if they can swallow.[4]
- Sweep up spills without raising dust and put them in a container for reuse or disposal; where possible, spilled product can be applied at label rates.[4]
- Store it sealed in a corrosion-resistant container, away from heat, light and sources of ignition.[4]
Safety and environmental hazards
People
Signal word CAUTION. The label says not to apply it to people or their clothing, and to keep children and pets off treated surfaces until the spray has dried.[1]
Pets
Don't apply it to household pets; cover fish tanks before treating nearby.[1]
