Q3. After spray, should I need to wash everything again?
Biokill® Insecticide is most effective if it is left where it has been sprayed. The residue can last up to 4 weeks for Biokill® Universal Insecticide and three months for Biokill® Long Lasting Extra Insecticide, depending on surface and environment conditions (sun light, organic environment, rain etc. will dramatically reduce the residual effect).

Q8. If my cat/dog happen to lick Biokill®, will that affect it's system and later on cause poisoning?
Cats / Dogs are warm-blooded animals and thus Biokill® is safe to them. We had few cases of high breed cat that reacted allergic to Biokill®. This is however rather exceptional and can happen even with humans (i.e. in some exceptional cases, humans are allergic to strawberries, plants etc.)
*Other Permethrin products may have caused some certain breeds of cats to have allergic reactions, which have far higher concentration than BioKill® Universal Insecticide (which has a dilution of 0.25%). If you have any uncertainties, please consult with your vet accordingly.

Q13. Why after spraying, there are still many insects?
If the treatment was done correctly and repeated after approx. three weeks, the insects will disappear. However, there are always insects coming in again from the outside. It is therefore imperative that in case of heavy infestation, professional pest control is being employed.
Q14. Why does my bottle of Biokill® smell unpleasant?
If the product is sprayed, there should not be an aggressive smell. However, in summer time, bacteria can develop quickly in the water, which in turn can cause a foul smell but no other side effects. We have in the meantime installed a reverse osmosis system in the factory to further improve our water quality, which has largely eradicated this problem.
Q15. Does it ham to people who drink/touch the Biokill® Long Lasting Extra Insecticide?
Q16. What is the best before date and can I use it after the shelf life has expired?
There is marked at the bottom of the bottle that stated the manufacturing date. Generally there is no expiration. The product will work for a long time. However, after 2 years, the effect will start to deteriorate slowly.
Q17. What the differenct between Biokill® Universal Biocide & Biokill® Long Lasting Extra Biocide?
Q18. Why the Biokill® Biocide is Odourless?
Q19. Can I just get a refill rather than buying a whole new bottle?
The law in Hong Kong does not allow for refilling by clients. The refilling would have to be done in our factory. Other countries do allow but Hong Kong does not distinguish between products that are safe and toxic products. They are all treated the same in the eyes of the law. You can return empty bottles to us and we will reuse the bottles.
