Did you get all of that junk out of your trunk and find that a rolling roach motel has sprung up where the beach blanket used to lie? Or did you find Kitty batting nasty cockroaches at night instead of her adorable catnip toy? Then maybe it's time to pass the mayo to these light-shy pests when you invite them to their last picnic.
That is, an empty or almost empty mayo jar can serve as a very efficient roach trap. If the jar is clean, grease its inside neck with preferably, non-petroleum, jelly and place a two inch piece of banana peel inside as bait. Otherwise, spare the spatula as roaches can schuss down the jar's slippery sides but then will be unable to side-step or crawl out.
When morning comes, cap the mayo motel and pop it into the freezer. Later, discard your catch into the toilet and lay the trap again, assuming that you have not already caught them all. If you do not catch any roaches at first, wrap the outside of the jar in a paper towel as your intruders may be Oriental cockroaches which cannot climb glass, so you need to provide them a foothold to reach the doomsday picnic.

Does this also work for those huge palmetto bugs?

Sean,
Yes, Mayo jars should captivate and capture Palmetto bugs also.
Thanks for stopping by and please drop by again.
Its amazing the number of great pest control blogs I have found out there since starting one at work.
For me, picking up non-chemical treatment tips like this in case I ever get a problem in the future is really interesting. Also, I know that ultimately I could always fall back on using more conventional pest control products responsibly if the problem got too bad/big.
Hello Danusia and thanks for visiting.
Yes, there are many very good pest control blogs in Cyberland.
I am of the optinion that like all of Nature, pests evolve to meet whatever challenges come their way so that many have or already/are changing and evolving to meet chemical onslaughts. Therefore, using inorganic repellents, baits and sprays only serves to make them bigger, badder, stronger and more resistant.
I have personally seen this happen with rats, roaches, head lice, termites and ants. Take care and please stop by again.
