Review: It Works, But You Must Be Persistent! - ​This powder and spray combination is effective, but it's a battle of persistence. The most critical thing to understand is that this will not kill the eggs. You must be diligent and reapply consistently to break the bed bug life cycle. ​Here's the method that worked for me: Powder (Weekly): I applied the powder weekly along all skirting boards, around and behind the bed frame, and thoroughly under the bed. This creates a barrier for new hatchlings. Spray (As Needed): I used the spray as a spot treatment whenever I saw a live bug.​It takes patience, but if you stick to a strict weekly routine with the powder, you will get the infestation under control.
Review: Bed bugs all gone so far. - Very good does the job.

## Questions & Answers

**Q: Does this work for mites in kitchen**
A: Yes. We used as a precaution to bedbugs( large block of flats, had a random little visitor from one of the neighbours) have used all around the kitchen walls and behind appliances..... haven’t seen anything since we laid it

**Q: do you need to spray again for full problem over with bed bugs after 2 weeks some still seem to be there**
A: You will need to be very meticulous with your hoovering of the bed and surrounding areas, regular laundry of bedding and tumble dry on high for a minimum of 30 mins. You need to repeat all of this and apply the spray at least every 2 weeks for a number of months as the life cycle of the bed bug is fairly lengthy and they lay around 100 eggs each. 
Best of luck.

Very good does the job.

### ⭐⭐⭐⭐⭐ Life saver!
*by A***R on 16 September 2019*

So grateful this exists! Didnt have a major problem with bedbugs, but even a few were my worst nightmare after reading how hard they are to get rid of. The problem can be dealt with when using the spray and powder together alongside hoovering everywhere; paying special attention to bed and mattress, along skirting boards etc. Wash bedding on a high temperature and tumble dry if you can for 30 minutes. I repeated all this once a week and will continue to do it all once a month (obviously still wash bedding and hoover every week). No need to have a break down like I did as it actually works thank goodness!!
