Today is Sun. 9/16/20. While I'm pleased that we saw some dead bugs - I am NOT satisfied for we walked into the house on Tuesday and seen live roaches in the kitchen and hall bathroom. We cleaned the floor under the refrgideor and found what appeared to be a nest of live roaches which we killed. Wednesday I woke up to find 4 or 5 bugs in my bed with me on my cleaned sheets ect. By accident we stubbled upon a nest of bugs - my husband took our bed headboard down to polish and found black specks which begain to move. He took it down to the burn site. Looking further he took the mattress out of the waterbed frame and found a black nest in each corner (how did the techs miss this site at the time they put on the mattress cover?) He then took the whole waterbed frame down and outside to be burned. He wanted to take out the carpet too but my 84 year old spouse was too worn out. So he cleaned the carpet and bug sprayed. Do the bugs live in the carpet? If so we will have to see about ripping out the carpet. Today Sunday 7 days later we saw a large roach in the kitchen cabinet witch the doors was closed and killed a tiny baby roach on the refigrator and a tiny baby bug my washed curtain in master bedroom. So do they nest in the window sill? I think you will be back soon. Thanks for you service. By the way do you have a quarterly maintain service?
