they swarm the motor part of my filter idk what to do

can I spray chemicals since it's external but just be careful so that they don't get in the water?
 
this will get rid of them bugs...i tryed the sprays..they don't work..get those "Combat" roach motels..1 box contains 6-8..use 4 in the whole house it'll kill'em..
 
I don't think that chemicals would be wise to use around the water. Maybe use some of those roach traps, place them near the filter and hope they go in it. I have never had this problem with my fish tank, and hope I never do. Good luck!
 
Roaches like fish tanks for a couple reasons.
1- water and warmth. They love warm, humid areas and need the water to drink
2-food and minerals. They can feed off of any algea or food residue on the tank. They also eat any calcium or salt deposits.

The motor on your filter is a nice warm place and its close to food and water. I would not recomend spraying chemicals at all. You could put a couple roach traps near by, or get some of the gel bait. I've had great sucess w/ the gel in my home.

The next possible problem you could have is if a dying roach, full of pesticides were to fall into the tank and die. I'm not sure if it would be enough to affect the tank, but personally I never take that chance.

If it were me, I would use traps or gel, and watch the tank and make sure none die in the water. I would also keep lots of carbon and media bags handy to try to absorb any possible poisons that might get in the water via roaches.
 
Two reasons....They love water and heat. Do not spray any chemicals near your tank. The best thing to do is get some stuff calle orthene pesticide and put down. This stuff is used for ants but is very effective on cockroaches. It smells like rotten cabbage and they roaches assume its food and when they eat it they die. The living roaches eat the dead ones and take this stuff back to the nest and it kills the entire colony. One application of this stuff and you will never have roaches again.
