Sierra, you say you live in an appartment complex, are there any new neighbors? The reason I ask is that I would look for more than the glue as the reason. Someone may have taken a vacation somewhere even, and brought them back in their luggage. Your glue may be "food" for them, but I would think that in a complex, they have many tastier options to go with. I don't know if roaches are common in your area (such as in the Southeastern part of the US), but around my area (WI) there are normally food or unclean reasons for them. I would let management/landlord know about the problem and make sure to keep your apartment clean - especially don't leave any food out.

Have you purchased or gotten any used furniture or electronics - like from a rummage sale or second hand store? I'm bringing up these other ideas because I tend to doubt that the glue alone could draw them - I can't imagine you having that much glue that it'd be a problem. Also, if you live in a complex, it's quite possible that management has a extermination company spraying the outside and common areas, so maybe they could checkout your appartment to see if they can find the source and take care of it.

Elmer's brand glue is made from milk casiens which are proteins you can consume and so can roaches.
But,I really think that there is no connection between insect pests and the glue. I mean you'd have to leave so much of it around that they'd be feeding on it to the exclusion of all the more accessible proteins and starches which tend to pack up in all the hidden corners of homes and furniture.

If you have roaches and you don't live in the south where they are native it is because some one brought them there.
This is a constant problem with apartment buildings and condominiums.
Turn your heat way down in the winter, use borax and something that no one ever thinks of is DEET.
It repels all insects including roaches and those god awful Japanese stink bugs.

You can get DEET in a variety of forms it's not terribly cheap but it lasts about 8 - 12 days before breaking down
Carcinogenicity:

Mice and rabbits exposed dermally to 0.02 mL of 10, 50 and 100% concentrations of DEET twice a week for 160 weeks had no significant differences in the number of tumors compared to controls.

Unless you are buying bulk from Vertellus Specialties Inc. ( the maker) you can't get any of those concentrations.

I tried once to make my own DEET treatment to prevent insects from entering my house. The stuff breaks down so easily it's useless as an additive to paint. But the compound in a powder or spray will persist for a week or two. So it's definitely useful.
