We live in a trailer park and we just found out that our neighbor has cockroaches. What can I use to repel them and keep them out of my house without making my dog sick? I am already cleaning and bleaching every surface in the house, as the exterminator says they don't like bleach-it burns their feet. We put our trash directly in the dumpster provided on a daily basis. We keep all food in airtight containers, and we were already decluttering just because it needed to be done. What can we do to repel these little nasties before they decide to move in over here? I own this place, so I can't move away; and it's so old that it can't be moved itself. Any other suggestions will be welcomed with open mind and arms. Thank you.
