| FUMIGANTS, SMOKE: Most Effective Vapona (DDVP) is, but a permit to use it is necessary; Dithio smokes ("bombs" or cans) are dangerous to humans; Diazinon and Cygon 2E are safe and effective sprays. A77-995 | 0 |
| FUMIGANTS, SMOKE: Non-toxic to Mammals or Plants There is none available; the safest one is Shell No-Pest strips, not a smoke; use it overnight then package again for later re-use. A77-43 | 0 |
