Question 1

How are cockroaches controlled?

Accepted Answer

We use a professional **bait gel**, applied in tiny drops in cracks and crevices. Cockroaches eat the gel and die. The method targets the entire cycle, including nymphs (young cockroaches).

Question 2

How quickly does treatment work?

Accepted Answer

The bait gel works progressively. The population decreases gradually as more cockroaches consume the product. The timeframe depends on the size of the infestation.

Question 3

Why is professional treatment necessary?

Accepted Answer

Controlling cockroaches with consumer products (aerosol sprays) is almost impossible:
- Sprays only kill cockroaches that are visible; the rest scatter and spread further through the property
- Egg cases (oothecae) have a hard protective coating that resists common sprays
- Long-acting residual pesticides are not available to the public
- Cockroaches can survive on minimal food; starvation is not a viable strategy

Question 4

Can I deal with cockroaches myself?

Accepted Answer

Only to a limited extent. Sticky traps can temporarily reduce the population but will never eliminate all cockroaches. They hide in the narrowest crevices — behind fridges, under countertops and in floor structures. Complete eradication without professional products is virtually impossible.

Question 5

Why do aerosol sprays make things worse?

Accepted Answer

Aerosol sprays drive cockroaches deeper into the property — spreading them to areas they hadn't reached before. This makes the infestation worse rather than better.
