i will write more on this still researching but learned from treatment plan on here that the things which plague us in our homes HATE sulphur. selsum blue shampoo has a sulphur derivative in it so i wake up bite free but smelling like rotton eggs, lol. my husbands father a country person in tn was telling us how they used to burn sulphur in homes tbrfore renting out or moving in to rid homes of any pests mold, etc. i believe this fell out of favor in our country because of the popularity of pesticides. :P i told my hubbie to call him to find out the safe procedure to do this. a few notes: the home has to vacant two days then aired out. all plants must be removed from home important note* furnace MUST be shut off. i plan on hubbie coming out here a weekend to help me do this, as with the size of our home will need help. when i know more will post, but would like some feedback about this. ann ok im adding the info recieved tonight about how to fumigate with sulpher powder. you can purchase sulphur from an older pharmacy or an apothecary . it is called flowers of sulpher . at champions pharmacy my parents bought two 4oz bottles of it for 4.99 a piece to treat my home. (one per floor) this home is 2800 sq ft. first, a few safety precautions:#1 furnace and gas MUST be shut OFF. #2 recommend resperator purchased from hardware storeabout 30-40 dollars for noxious fumes. #3 saftey glasses to repel fumes from pesticides (sulpher can be an irritant to man) #5 remove all plants from home or they will die #6 have somwhere for your family and pets to stay after this is done the home must be vacant for two days. things you will need: 4oz of sulpher powder (or flowers of sulpher) small barbeque grill from walmart or dollar store for about ten bucks. (one for each floor) . charcoal briquettes. sand. a pan to line bottom of grill if any holes to prevent a fireand tinfoil if needed too. (you may try a large can up on cinder blocks like a huge coffee can) ok, now what you can do is get the grill (or can on blocks)open all windows (to protect from carbon monoxide) wear saftey goggles and respirator Make sure furnace is OFF and gas and all plants,aquariums, pets removed open all doors to rooms and if havbe ceiling fans turned on to disperse smoke. ,line bottom of grill with panand foil if needed then layer of sand or can with sand (to prevent a fire) and put in briquettes with an open window. do this in center of floor away from furniture, fabrics,combustibles etc . have all windows open at this point. get the coals to glow( if multiple floors start at bottom one ) when coals are glowing,shut all windows and put 4 ounces of sulpher powder on top of coals and then LEAVE. if basement or lower flor has an entry door shut door (you can also place a towel under bottom od door) if have one then proceed to higher floor and repeat steps then exit home, making sure all window are shut make sure smoke alams disabled also. safty precautions must be observed. then leave home for two days when come home, may want to wear respirator and goggles, open all windows let air out for awhile. wash any dishes in cabinets and hang outside clothes and such to air out. keep in mind will be REAL stinky (sulpher smeels like rotten eggs) but any mold black specks bugs pests fibers ALL will be DEAD. you may want to febreeze house to rid it of any lingering odors. Please be careful with this procedure i dont want to get any bad feedback lol but is how they used to fumigate homes and how they still do in united kindom for greenhouses. anyway, if want home rid of all pests without pesticides, this will do it but BE CAREFUL. i will not be responsible if safety precautions are not observed. so make sure you are careful in this natural older way of fumigation.
