Bed bugs are small, flat insects that feed exclusively on blood and hide in tight crevices during the day. They reproduce quickly once introduced to a home, with females laying several eggs per week that hatch in warm indoor conditions common across California. Their flattened bodies allow them to slip into mattress seams, baseboards, and electrical outlets where they remain undetected until numbers grow large enough to cause noticeable issues.
An infestation often starts when a single fertilized female arrives on clothing, luggage, or used furniture. In multi-family buildings the bugs then move through wall voids, plumbing chases, and shared hallways, allowing one untreated unit to re-seed neighbors. Homeowners typically first notice itchy welts on skin after sleeping or small dark spots on sheets from digested blood. Early signs are easy to miss because the insects avoid light and only emerge when hosts are still.

DIY sprays and over-the-counter foggers rarely reach all harborages and leave eggs untouched, allowing rapid rebound. In California multi-family housing the problem compounds because bugs readily cross into adjacent units; treating only the reported apartment lets survivors return through the same pathways. Operators must coordinate access across units and use methods that penetrate deep into cracks rather than surface treatments alone.
Effective work requires locating all active sites through thorough inspection, then applying heat or targeted materials that reach every life stage. Follow-up visits confirm elimination because eggs can hatch days later. Single-unit efforts almost always fail when surrounding apartments remain untreated, which is why operators insist on building-wide access in attached housing common throughout the state.
Technician insight
In Los Alamitos the thing that catches most people out with Bed Bug Treatment is how fast bugs move through the older multi-family buildings with shared plumbing runs; treating just the reported unit lets them re-enter from the neighbor the same week.
Multi-Unit Spread in Los Alamitos
A homeowner reported bites along one wall of a 1970s apartment. The operator found live bugs in the headboard and traced activity through a plumbing chase into the adjacent unit. Coordinated treatment of both apartments plus encasements stopped the movement. No further signs appeared after the follow-up inspection.
