We recently bought a house sight unseen, we later found out that there was an infestation of cock roaches, and termites. We bought everything on the market for the cockroaches. My grandmother told me to cut some crabapples (hedge apples?) in half and put a half of the crabapple where I had seen the roaches, well I did not believe that it would work, well it did! We no longer have the roaches or the termites! Be careful, the crabapples are poisonous to animals and humans! I hope that this helps you all.
Check out these photos.
This is our crab apple tree in full bloom. It is absolutely beautiful against the clear blue sky.
The flowering crab tree in my front yard is only 2 years old, but look how gorgeous it is this spring!
This is a flowering crab apple that I planted 15 years ago. It smells wonderful and is just beautiful for 2 weeks. The birds love to hide in it and fuss at the squirrels.
