## Questions & Answers

**Q: how would this be used to prevent bed bugs?**
A: I have lived through this nightmare with tenants bringing. If you rent, do NOT try to do it yourself, depending on the infestation they can be hard to eradicate. Do the right thing and notify. Don't risk taking them to someone else's property if you move.   Look up how to check for them carefully with flashlight.  I used a professional company--3 sprays 2 weeks apart using a different mix chemicals each time, and still a tenant saw one that got away in a box of stuff she had and did not check it carefully when un-bagging, that was 10 days after 3rd spray so had them come and spray again and check, and they got rid of their old mattress/box spring and two ripped couches. I think it had been going on for months, but new roommate was sensitive to bites and figured it out, so I would say they bred for months.     The prep work is crucial to winning the war (you can look that up,plenty of info online) plus I have used this along edges of rooms, corners of closets, backs of dressers, drawer backs and inside when drawer removed, sockets, and will continue to do every few weeks after vacuum for safeguard. You don't usually see them as they hide during day, unless you have a heavier infestation, alcohol will kill them on contact and used in spray bottle for shoes and some tiny areas.  All exterminating companies will do a free inspection to see if you have them and not hard to learn to check yourself and where. I highly advise to be diligent for several months and not let your guard down to quick!

**Q: Does this product have any other ingredient besides DE?**
A: This is a mechanical insecticide, that is to say it is Diatomaceous Earth powder, a soft siliceous powder which lacerates the abdomen or if ingested kills the insect within 48 hours. The insect quite literally dies the " death of a thousand cuts " . It's  85% DE and 15% other which is most likely a filler unspecified however. So far my experience with it has been very positive, I haven't seen any insects since distributing this powder. I do recommend the use of a dust mask when dusting your rooms as we should always err on the side of safety. If you have a problem you'll love this product . BTW remember it must remain dry to be effective and keep in mind that with these type infestations persistence is key to winning so don't let up.

**Q: Is it pet friendly?**
A: Yes. This stuff just comes from "diatoms". Basically, their crustaceans. It cuts the bugs exoskeleton and they dry out, but it takes time for them to pass through the dust for it to cut them up and they lose body water. Doesn't hurt us or animals, but I wouldn't dust it to the extent that you and the pets are breathing it so much.  Make sure you change your house filters often or it can clog up the systems and you will have another issue.  Whatever you use...if it says "residual", that is what is not safe for pets. It can get in their pads and absorb poison into their feet. Most other control treatments just need to get dry for 8hrs.

**Q: What is the difference between Harris diatomaceous earth and Harris bed bug killer diatomaceous earth**
A: None that I know of.

### ⭐⭐⭐⭐⭐ IT WORKS, WORKED VERY WELL FOR ME!!!
*by R***A on March 7, 2020*

THIS STUFF WORKS!!!!!!! I GOT RID OF THE BED BUG PROBLEM AND HERE IS HOW I DID IT!!! I got a new bedbug problem because of one of my previous 2 roommates who took over a bedroom in my apartment in quick succession. Soon after, an overnight guest visitor of mine complained promptly of huge rashes. I looked up and sure enough, there were HUGE bed bugs around the mattress. There were smaller bed bugs and almost transparent albino like little bedbugs, which showed they were reproducing. The room was about 9 ft x 12 ft. Before you begin the treatment, always remember to wear work-horse clothes you intend to sully and wash away because small bedbugs or eggs can stick to your clothes and you might unwittingly transport them out of the room to new areas. After every step you might want to head straight to the bathroom, put your clothes in a plastic bag to laundry or put them in scalding hot water for an hour. And then dry them at high temperature to kill any eggs that might have gotten on to your clothes while you were treating the room. 1) I took out the bedsheets and the pillow covers out. I took these pillows and blankets/sheets/bed-covers/pillow covers separately into separate plastic bags outside the house in a shed. They would be put in for washing after 2 weeks. (There is a reason to this - bedbugs start migrating after 5 days of not receiving food and 14 days is enough to starve them for the time being, before taking the bedcovers, sheets, pillow covers and blankets to the laundromat. I will come down to this again later. 2) after a lot of research, I sprayed, using the anti bedbug spray nozzle attached to the gallon, in every single little crevice, in all corners and seams of the mattress and the covers (which I had take over into the plastic cover outside). I also sprayed the bed frame in every little crevice, nook, cranny, joint and fold of the frame. I also sprayed the table and the floors under the bed frame, the walls as well! I left the room as is for the next 2 days. Checked it. Many bedbugs were still alive, but it appeared that they had weakened. 3) REMEMBER THAT THE MATTRESS AND the bed frame must be very dry before you progress to the next step! Now it was time for the diatomaceous earth to do its magic! I took a painstaking 1 whole day, from morning 11am to evening 5pm to work on this treatment. I used the diatomaceous earth GENEROUSLY with the nozzle, to put a huge load of dust into every single seam, corner, above and under the seam, or a fold, around the bed, at the inside above and inside under at the top of perimeter of the mattress and the under perimeter of the mattress. Effectively I had caked every single corner of the seams and folds and crevice of the mattress with the diatomaceous earth. If I found physically big bed bugs, i killed them. I killed every I could get my hands on. Remember every big bug is worth a thousand of the new generation. I used copious amounts of the diatomaceous earth in every book and cranny, crevice and fold of the bed frame, not just the mattress. Same thing for the walls, the study table next to it and even the FLOOR, around the legs, to prevent the bed bugs from migrating and I put huge powder perimeters around the bed and also at the room entrance to stop them from exiting the room and migrating to the living room where we sat for TV... I left the room untouched for about 8-9 days... the results normally say that bedbugs start drying out and dying in just 3 days and most start dying in 5-7 days, the eggs and larvae die out faster when they come in touch with the earth. I treated the room in this procedure with diatomaceous earth for a 2nd time, just in case, and let it alone again for another week. I was nervous if it had worked.... IT HAD WORKED!!!!! I HAD LITERALLY OBLITERATED the whole room with diatomaceous earth everywhere and let it work its magic for 2.5 weeks and now it was a roaring success!! My new flatmate who temporarily stayed in another guest room, upon moving in there, had zero complaints! I looked up the crevices and folds, I could see dead bedbugs dried out and their shells everywhere. This is the second time I have had a great experience with diatomaceous earth. I had done this exact same treatment in the year 2007 and it had worked very well!!!!!!! :) the room is free of bed bugs and i know how to defeat them! I have seen infestations far more serious than mine... I dont know how I'd take care of those. But my current infestation was a new one so it was probably relatively less spread out and easier to defeat. But I've won this battle twice now, once in 2007 and now in 2019! I am a satisfied customer and I know it works! You just have to be really thorough. Going back to the clothes, pillow covers, blankets, sheets, etc, I put them in scalding hot water in a bucket, then took them to the laundry to launder them and dried them at very high heat for 40 minutes. This destroys every bug and egg. The job was well done! My home is still bug free and I didn't sacrifice any furniture or linen or pillows. Good luck!
